If you had a choice of a 3006 & a 300 wby and wanted to convert one to a 300 H&H, which would be a simpler conversion - which would you choose?

All things being even, in other words the rifles would be 2 wby vanguards, or two remingtons, or two CZs, etc.

I am just curious about which caliber is the better starting point.

Model suggestions are certainly welcome here since I don't have a rifle to convert as of yet.

I've heard the the 3006 is the best but isn't the 300 wby based on the 300 H&H? and if so wouldn't it feed better right off the bat?

So many questions and hoping for a few opinions - Thanks.

Quick answer is
with the wby you have the right bolt face but you would have to set the bbl back a good bit.
the 06 you would need to open the bolt face but the chambering would not require as much set back. there are other considerations but this is a starting point both rifles would probably need a little tweaking to function and feed.
Hope ths quick assesment helps a litle.

Riodot-

I'm with you. I think converting a .300 Wby to a 300 H&H would be much easier and simpler given that the case length for both rounds 2.85 inches. Thus, getting an action already opened up to accept a case that long would seem to be more than half the battle. With an '06 length action, you would have to open the action up and most likely open the bolt face to accept a cartridge with .532 case head as opposed to .473.

First off -- I don't fully get the question. Why the reference to two rifles - vanguards, remingtons, CZs?

Anyway, with the Vanguard or the Remington, you have to start with a rifle already having the correct boltface, which means a magnum. I don't think it's practical to open these bolts to a magnum from .473. And if it's already barreled in 300 Weatherby, then you'll need to start over with a new barrel blank. I doubt the factory barrel with the Weatherby chamber could be set back enough to clean up with a 300 H&H reamer. Either the Rem or the Vanguard action would be long enough with no modifications.

I think the CZ magazine is long enough to take the 300 H&H, so it may be possible to rechamber the factory 30-06 CZ barrel to 300 H&H, and open the bolt face, and mess with the feeding a little, and have it.

The fine details about the CZ would have to be checked by someone who knows more than I do though.

When converting, are you you planning on saving the barrel? With the .300WBY that's a NO-GO. The chamber will not clean up. If you're planning on a new barrel it's a no brainer, go with the one chambered for the weatherby and just get it rebarreled.

I wouldn't do the CZ because you'll have to step into the huge (heavy) magnum action to make it fit.

I wouldn't use a Howa or a Remington because there is nothing classic about either one and the .300WBY outperforms the old H&H so what's gained?

I did it with a Winchester M70 Classic. I went from a 7mm Mag to a .300 H&H. It wasn't a big deal. Another option and I think a VERY cool one would be a Ruger #1. I would pick a .30-06 in the little light weight model with open sights and have the barrel rechambered.

Hello!!! If you have a 300 weatherby --- you can shoot a 300 H + H in it without any conversion. You will just make 300 weatherby cases out of the 300 H + H cases.

Yea, but does that have anything to do with what the guy asked?

Then I just have to find a way to change them back.

Sorry if that was unclear - was just asking if you found two of the same model rifles, one in 3006 & one in 300 Wby, which would be the better choice to start from for a conversion.

I didn't want to get into the brand in 3006 would be better than that model in 300 wby, etc.

I appreciate your info!

That is a plan with real merit!!!

Thanks

In a bolt action, I would think that converting a 300 H&H would be the easiest route. Your bolt face, magazine box and follower would be the correct sizes and the feeding geometry would probably be close enough that it wouldn't take a major overhaul to make it feed properly.

You can probably find a pre64 mod 70 in 300 h&h; thought I saw one on Griffin & Howes website. Also remington made a limited edition in 300 h&h, used to see them at gun shows fairly regularly

Ok I'll have a go at this.

Assuming that you want to end up with a .300 H&H. I'd start with a .30/06.

You'd need to open the bolt face and extractor, rechamber the existing barrell and then lengthen the magazine box, possibly modify the magazine platform and rework the magazine rails so that it would feed.

If you started with a .300 Wby you'd have to rebarell it, the extractor would be fine, the platform should be fine but the magazine rails at the shoulder might already be too wide to feed properly.

I've done .30/06 to .300 Wby and the work is the same.

Remember free advice is generally worth everything you gave for it.

The easiest conversion to 300 H&H is to buy the parts I have and have a gunsmith assemble it.

I have a Charles Daly action, with magnum bolt face, FN factory magazine for 300 H&H, Douglas #3 .308 chrome moly barrel, etc. I have enough parts for a complete assembly, including safety, trigger, stock, leupold bases, etc. It depends on what you want. I have a stainless .308 barrel also. I could sell just the action, or the complete assembly kit. If interested PM me and we can discuss, and I can think about what I would sell it for, after you express interest.

I guess I'll have to chime in on this one as well. I've been pondering the same thing I think. I'm looking to get into a 300 H&H that won't cost a guy an arm and a leg, just something to take out and punch paper and would like it to be in 300 H&H just because. After read several similar threads and considering the work needed I've come to ponder this question. Isn't the fastest cheapest way to move into a 300 H&H from something "fairly readily available" to start with a 375 H&H and just rebarrel or am I missing something??

Tom,
Of course you are right - but ---. I have looked at many 375s with that notion, and all had some issue that made it just not as practical as it seems. Most were too nice and also too expensive to just buy and rebarrel. I missed a great deal on a Winchester Mod 70 classic once. Then there's the other end, say the Savage, which could be rebarreled easily, and I think any of their magnum actions is long enough.

Again, the Remington magnum action is long enough, and so is the Weatherby/Howa. The push feed winchester action is long enough with some modifications.

Heck, there's a CZ action in classified right now that would make a great 300 H&H, but it's better suited to the big bore stuff. I think the magazine is big enough to hold six or maybe seven cartridges in 300 H&H - I dunno for sure. The final result may be heavy, but a guy could ask McMillan to make a light version of their stock for it to compensate a little.

Anyway, if a guy is determined enough, a solution can be found. However, I sometimes stop and think about what the 300 H&H will do that the 30-06 won't do - maybe 100 fps - maybe a little more? And there are a whole multitude of issues resolved by just shooting a rifle chambered in 30-06.

I have all the parts to assemble a 300 H&H, in a pretty classic setup - mauser action, factory magazine, etc., but most likely I'll never finish it. Right now it's about number four on my list, and it keeps getting ratcheted down as my interests change.

Right now I'm interested in planning my next hunting trip, more than accumulating more rifles.

Obviously, the '06 would be a mere rechambering job, with a bolt-face alteration job and action rails being opened slightly, perhaps.

But to change a .300 Weatherby, I suspect you'd have to get a new barrel, at the very least! (Unless your .300 WBY has a full-diameter bull barrel so the Weatherby chamber can be cut off completely before rethreading!

In addition, if a magazine box and receiver rails are of the proper width to feed a .300 WM, they may be too wide to retain .300 H&H cartridges in the magazine when you open the bolt.

I too like the Ruger No. 1 idea best, starting with one in .30/'06 - preferably a 1B....

While we are at it, I have a similar project getitng underway in the fall. I have a M70 in 30 06 to be sent to Dennis Olson for conversion to 375 H&H. I noticed the current rifle has a cheesy plastic-feeling magazine. Since the rifle will be a 3+1 configuration, does the gunmaker do anything other than use a factory box?

Also, isn't it my understanding that most top flight gunsmiths prefer to start off with the 473 bolt face so they can covnert it their way?

I bought one of those used, in mint condition 2 years ago. It is a great shooting rifle. If you can find one I think you would really like it.

The .300H&H was the 1983 edition of the Remington M-700 Classic.
