Gentlemen, I have been toying with the idea of making up a rifle in 9.3 x 375 Ruger. I have a FN Supreme action that has the bolt opened up to Mag cartridges. Is the diameter of the case head on the 375 Ruger the same as the magnum dimensions? Has anyone here tried this combination? Just seems to me to be a pretty "snuffy" 9.3. Thank you, Hoot | ||

The .375 Ruger case head is the same as the .300 win mag ....it just lacks the belt. Many rifles have been built on this case.....It's probably a very commonly wildcatted case today..... I have a .416 Ruger reamer and I'll bet there's a .xxx ruger anything you want out there somewhere.....even a .395 Ruger reamer... I must say however that necking it down .009" isn't exactly much of a difference.....why not .358 Ruger? /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

Vapodog, I realize that one can do anything with any cartridge but what I was thinking of trying to increase the velocity of a 9.3 x 62. I have one of these on the same action with a 26 inch Lothar Walther Barrel. I get about 2400 to 2450 with the load that I am using. It is a load a little on the warm side. However, there are no high pressure signs and bolt lift is easy. I was thinking that if one could get a 9.3 bullet up to 2600 to 2650 it would be a better long range cartridge. I would think that a .358 Ruger would be pretty much the same as a .358 Norma. I thought that I would ask some of the guys here if my desires are realistic and their satisfaction with the cartridge before I invested in a reamer and barrel. How does your 416 Ruger perform? Does it exceed the 416 Rem? Thanks, Hoot | |||

Why not go for a 9,3X64 Brenneke? It will deliver what you need.. | |||

Buffalo, I was wanting a cartridge that would fit in a standard length FN Supreme that was originally a 300 Win Mag Rifle. Would a 9.3 x 64 Brenneke fit in the above action? Thanks Hoot | |||

Hoot, I like the 9,3 calibers having two 9,3x62s and a 9,3x74R ... but I gotta ask ... why bother to build an oddball 9,3 when the performance of a .375 Ruger is just fine and it makes the DG minimums in all of Africa?

Fit yes. Function I doubt it. The 9.3x64 head is only .496" vs .532" for the 300wmag. With that action if you really need a 9.3 then a wildcat on a short magnum case or the 375Ruger case. But like others have said other than saying 9.3 it wouldn't do anything the 375Ruger wouldn't. As usual just my $.02 Paul K | |||

I just wonder what you would get for vel. shooting 320 Woodleigh PP out of the .375 Ruger case ie. 9,3-.375 Ruger--sounds like it would be a hoot for sure  am getting 2216fps with the 320's out of my VZ24 9,3x62 so far with 56grns. of RL15. just do it Hoot. | |||

the 9,3 sisk would blow them all away... far be it from me to naysay a wildcat, but are you SURE you want to spend $600 for dies and reamers, and then another 1000 for the proper gunsmithing (assuming you aren't doing it yourself) for -.009 from the stock ruger? opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I committed to building a 9.3x338 just before the anouncment of the 375 Ruger. I had already bought the reamer and ordered the dies from Redding, so I went ahead with the project on a Ruger action. I have not been dissappointed, but I don't know if I would do it again since things have changed with the intro of the 375 Ruger. It's a very good wildcat, and using the 375 ruger case as the basis is a good choice too, and will have a little more capacity than the 338 case. Of course the 375 Ruger is more practical. I tested one load using 250 gr ballistic tips, and got a little over 2800 fps with RL 15 powder. I can load it down a bit too if I want a mild load approximating the 9.3x62. OK, yes I know it duplicates the 9.3x64. Case capacity of the 9.3x338 is within .5 gr of water of the x64 case. But I think the value of being able to use an action that feeds the cartridge, with no modifications, is so important that I would still choose a wildcat 9.3x338 or 9.3x375 Ruger over the 9.3x64. They are all wildcats to me, since ammo for the x64 is so scarce. In fact I had a 9.3x64 pre-fit barrel from Pac-Nor, and a Mark X Mauser action to fit it on, which I sold and the guy still complains about it not feeding right after having it assembled by a qualified gunsmith. And it holds three down, the same as my Ruger with the magnum brass. The dies & reamer are about the same cost for either of them. Incidentally, the cost for the dies and reamer is close to $300, not $600. My 9.3x338, which I call .366 Alaskan, feeds super slick in an unmodified Ruger receiver. It seems to be very easy to develop loads for, but I have not yet had the time to really work with it. RL 15 seems to be the powder of choice though. Good luck on your project. My reamer has been used only one time. It is possible for you to talk me into loaning it to you for nothing but the shipping cost, to a qualified gunsmith who can use it properly to finish a chamber for you. I suspect it can cut many chambers before showing wear, if the bulk of the cutting is done with another reamer first. PM me if interested, and we can discuss details, and ideas.

Hoot, The 9,3x64 will fit in a standard action. I had one on a standard action and rechamber it to 376 steyr. Mike Legistine actu quod scripsi? Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||

Hoot, I don't mean to start an argument here, but the above info is a bit misleading, or perhaps incomplete. Sure the 9.3x64 will fit in a standard action, but in your initial post, you said your bolt has been opened to take a magnum cartridge, which means it's now too big for the 9.3x64 case head. You can open up a standard boltface (.473) to accept the 9.3x64, but as far as I know it's impractical to reduce the bolt face of a magnum (.532) to fit the x64. Although the 9.3x64 is a great cartridge, the actions I tried it in would take only three cartridges in the magazine. I'm sure there are some that will accept more. The brass, dies, and reamer are expensive for it, just like for a wildcat. Factory ammo is practically nonexistant in the USA. Also every action I tried the cartridge in, and the 376 Steyr too, had feeding issues with the feed rails, aside from the bolt face issue. I know it's a fact that many, many rifles have been so chambered, and the feeding issues resolved, but I'm just saying that in the actions I tried, including several Rugers, and Mausers there were issues to be resolved. On the 9.3x338 though, there were no feeding issues at all, starting with a magnum bolt face. My action is completely untouched, as it was when it left the factory. I like that very much, and on the other hand it irritates me greatly when I have a rifle that has feeding glitches. I have had mixed results from that, and frankly more often than not I never did resolve the problem, or had a gunsmith make it worse, and eventually just got rid of the rifle. Nowadays, if an action doesn't feed right with a given cartridge, I don't mess with it, and find another combo. I'm simply saying that if you choose to go with the 9.3x64, make it feed properly before going any further with the project. As for Mike "rechambering" his 9.3x64 to 376 Steyr, I'm sure he meant that he rebarreled it, since the bore diameter is different, and the x64 is longer than the 376 anyway.

Yep! The 9.3x64 is essentially a beltless H&H round. I.E.: .507 for the x64 & .511 for the case above the belt on the H&H. You won't get anymore mag capacity by using the x64 cases instead of the H&H or the Ruger cases. The differance is too small to accomodate another case! The case head of the x64 is rebated, @ .495. A bolt opened for the H&H and Ruger is going to be too big for reliable feeding using a x64. I used a Brno 600, it had a bolt opened for the .473 cases. | |||

Gentlemen. Thank you for taking the time to answer my post. As I said from the beginning, I was toying with the idea about necking down a 375 Ruger to 9.3 caliber. It seems that since the 375 Ruger came out there has been a lot of necking up and down of the case. I was interested in talking with someone who has done it so I could get all the "look out for" and what the performance of the cartridge was. I know that there are factory cartridges that would seemingly cover my desires as to performance. Albeit, these are European cartridges and brass can be an issue and for the most part the dies are just about as expensive as a wildcat. I have also in the recent past, looked into a 9.3 on a 338 case and 358 Norma case. Then the Ruger came out and I thought that this might be what I was looking for. One thing that I did not consider is the availability of 375 Ruger brass. It's scarcer than 9.3 x 64. I don't know of a source of brass for the Ruger other than buying loaded cartridges. If any of you know of a source, I would appreciate knowing. I have more than enough rifles to cover every small game, big game, dangerous game and target situation that I would ever find myself in. But,building rifles is my hobby and business now that I am retired. Life is not just about what you need, it is in large part, what you want. I sincerely appreciate and thank each and every one of you who took the time to answer my post. I will use the information provided in making my choice. Again, my sincere thanks, Hoot | |||

Obviously, they gunsmith were not qualified. The '64 have no frills, it is just as easy to make feed as the .338 Win mag. The '64 is a super cartridge - super-duper - but holds only 87 grains of water, compared to the .375 H&H's 96 gow, about the same difference as on the .300 WinMag and .300 Wea'by, to put it in perspective.

Solving feeding issues is apparantly something this gunsmith was not best at, but the other work I've seen from him was good. When I refer to proper feeding, I'm talking about a full magazine, all cartridges pushed into the chamber, and ejected, with no glitches. The problem with feeding is that from a customer's perspective you can't tell in advance whether the gunsmith can solve it or not. It's easy to critize after the fact. You have to take your chances, and most times it's after you get the thing home, and at the range that you notice the small but irritating glitches. So then you have to decide whether to live with it or send it back or send it to another gunsmith. Generally gunsmiths don't like following another smith's job. And what's the chances of improvment with the same smith the second time around? Anyway, it's not just black and white. Some of the most irritating rifles I have owned would feed just barely good enough to cause me to be indecisive about leaving well enough alone, sending it back to the smith, or selling it. Therefore, such a rifle would generally not be the one to go to when deciding what to take hunting. The 9.3x64 is definately not as easy to get to feed as the 338WM. The reason for this is that I choose an action already set up by the factory for the 338 magnum or similar cartridge. That way the bolt face, magazine width, follower, etc. is already done. It can't get any easier than that. It's easy to tell if the action will feed that way, without spending any more money on it. If starting with a standard action, say for a 30-06, the conversion may be just about the same whether going to the 9.3x64 or the 338, but again I would't convert a standard action to a magnum. I would just get a magnum action to start with.

I have two 9.3x64's, one built on a CZ550 action and the other on a pre64 M70. Both feed smooth as glass and I do not recall the maker having any difficultly. The Winchester was originally a .30/06 that Danny Pedersen rebored/rechambered. | |||

Now that you mention it, I do remember trying some dummy 9.3x64 rounds in a CZ 550 that was chambered in 9.3x62. As I remember, it fed them good. Naturally there was a hang up with the extractor and bolt face, but it looked like an easy conversion to me - just rechamber, and open the bolt face and extractor. If I wanted a 9.3x64, my first choice would be to get a factory CZ 550 in 9.3x62, and get a gunsmith to convert it. I doubt that it could get simpler than that conversion. I also tried the same dummy rounds in several Mauser actions I have, military and commercial, and I tried some dummy 376 Steyr rounds too. It looked like those actions could obviously be made to feed, but with a lot more work than the CZ. As I remember, I tried a Ruger 30-06 action with the dummy rounds, and there were some issues beyond the bolt face and extractor to be resolved, which meant to be avoided to me.

i don't see the point. I love my 9.3X62, but if I wanted more velocity or power I would go to one of the standard .375's (probably a H&H, but would consider the Ruger). 375 bullets are easier to find, and you have more choices. | |||

A friend and I were recently discussing this and he mentioned that in his opinion if something more than the 9.3x62 is needed, then probably a guy should step up to a 416. I tend to agree with that view as well. I really like my wildcat, but I had it made just for the heck of it, not because I needed it. I really think the 9.3x62 is perfect and enough in that class, and the extra speed adds little, except entertainment to me.

I agree with Kbluewy. The 9.3X62 seems a perfect balance of power, rifle weight, and recoil. | |||

Hoot, i had something like that a few years ago. I used a 375 Dakota case necked down to 9.3 It really liked a heavy dose of RL19 and a 250 NorthFork.
