I have a Ruger No.l chambered in 7x57 coming in, and would like to recieve info concerning 175 gr Hornady RN bullets.
What powder are you using? Speeds? Etc.
Also, what is generally the most accurate bullet your gun likes?
I'm mostly interested in the 150 to 175 gr range.

I've never owned a No.l before, but did handle one many years ago, and have a fondness for the iron-sighted version with the quarter rib, barrel band swivel, Alex Henry forend, etc, of which I ordered.
To me, this is a very classic rifle, and the 7 Mauser is a classic cartridge, so I chose this one, and put the 338-08 (and 376 Steyr)on hold due to no stainless Mauser actions available yet. I think I made a worthwhile purchase. ~~~Suluuq

RG,
I believe you made a worthwhile purchase too. I have a 7x57 in a No.1 RSI (mannlicher stocked version) and use it here for everything up to moose. I haven't shot any 175's from it, and don't have a chrony, but have shot quite a few 150's and 160's from it. My handloads come straight from the manuals, guess I'm not too creative, and the loads are pretty boring but they are accurate as I am, trajectory is flat enough for the way I hunt and never been lacking for power. Lately been shooting some Brenneke TIG factory loads and highly recommend you try some of them. My rifle loves them and Brenneke post their recipe on their website. Works well on Deer, Sheep, Goats and Caribou. I've got a 338 in a No.1 S that goes after moose.

I have a "Liberty" Model 1A in 7X57 purchased in 1976. I use mainly Nosler Partiton bullets in it, in all weights up to 175-grains. This rifle will deliver over 2650 FPS with Nosler 175 or Sierra 175-grain PSPBT bullets, with very accepatble pressures using either RE 22 or Norma MRP in Remington cases with Fed. 219 primers. But, mine has a very long throat, which almost amounsts to a freebore situtation, and I don't know if Ruger is still throating their 7X57's this long. I have never used the Hornady roundnose bullets in it, I believe the round nose is a handicap for any shooting beyond 200 yards.... It is also a very accurate rifle.

Thanks for the responses. Although I'd like to try 175 gr RN's, my 'chosen' bullets will be the Grand Slams and Partitions, for most of my hunting of caribou and black bear.
The RN just seems like a classic bullet for a classic cartridge in a classic rifle.
I have several load manuals to choose from, but will need to purchase the suitable powders required, as my meager selection doesn't have them. ~~~Suluuq

Rusty, the 7X57 works best, when using 175-grain bullets, with a powder of a burning rate approximately the same as H4831, but of smaller grain size and greater density. This is because you can't get enough H4831 into this small case to get optimum velocities. Two smaller-grain, denser powder of burning rate like H4831 are Norma MRP and Alliant Re 22. There may also be a Vitavuori powder that meets this requirement, but I don't know which one it is. I think you'll be amazed at what the 7X57mm will do in an action as strong as the No. 1!

Well, I got my No.1 a few days ago, and this is a very nice looking rifle! I'm already wishing for another one.
I've yet to purchase loading dies, brass and bullets, but I'm in no hurry, because I don't have any suitable powder in stock yet. A local dealer sells ammo, so I'm likely to purchase from him before too long. Thanks for the info. ~~~Suluuq

Let us know how it works for you-particularly on the bigger critters up there!

Question... will the Hornady 175 gr RN, crimped in the cannelure, chamber in the No.1? I noticed two 175 gr designs, with their cannelures at different locations. (This might seem to be a silly question, but I once read Ruger went to a shorter throat, albiet in a different cartridge, so it's confusing, also due to the differing cannelures on the Hornady bullets.) Thanks. ~~~Suluuq

Ruger may have changed their 7X57 throating. It will chamber OK in mine! (Made in '76).

Thanks for the response. i figured it would be cheaper to ask, then to purchase a bullet I can't shoot. Well, I'll buy a box of 175 RN with the other's, and find out.

Also, has anyone got any expereice with the Hicks Accurizer? This one attaches to the hanger tip, and allows for a screw to put pressure up on the barrel. I seen it in Brownell's, and it seems like a good thing, considering the No.1 has accuracy problems with some rifles, and a simular thing is welded on the tip to help (an artical by Jon Sundra mentioned this weld-on screw attachement, that it helps some). ~~~Suluuq

Great gun, great caliber. Have fun!

Rusty,
I highly recommend you shoot your rifle with different loads before fussing around with any accuracy improving things. Every single No. 1 I've had (including the 7x57 RSI) have shot very well without doing anything to them. I've heard that some don't, but I've never seen one of those.

Yukon jack... Yes, it was my intention to shoot the rifle, and develope loads first, but I like to obtain pertaining info ahead of time, it makes it easier down the road. Thanks. ~~~Suluuq

Indeed it does Rusty. Good luck with yours, I hope it works well for you. If you have problems with those 175's, try those Brenneke 160's. They shoot like a gangbusters out of my RSI.

Rusty...

Please keep us posted. I am considering the same rifle and have also been concerned about the current throating. A local shop has one of these on the shelf and I've been absolutely drooling over it, so can imagine how you feel.

When loading for a No.1, I totally ignore crimping grooves, if any! I just drop a bullet into the barrel, let it slide forward as far as it will go, then drop an empty, trimmed, resized case behind it. Slide the case in as far as it will go, until it touches the bullet base. Then use a caliper to measure how far the case head protrudes from the breech end of the barrel. Add 2 or 3mm to this measurement. If a boat-tail, add the length of the bottal as well. This is your initial bullet seating depth. (Be sure to remove the test bullet from the barrel after this procedure!!) Good luck!!

I called Ruger today and asked about the throating on the 7 X 57 1a. The gal I talked with, who seemed to be interested in filing her nails at the moment, said that there were no changes to the throating or other specs.

I have one of the earlier Ruger #1A rifles in 7x57, and it is a keeper. I have not yet gotten around to trying the 175 gr. Hornady RN's in it yet, although I do have a goodly supply. Limited testing wirh Sierra 170 gr. RN's shows a great deal of promise though. Problem is, you'll really have to hunt around to find any. Sierra dropped them from their line about two years ago. A powder that has shown real promise in the 7x57 cartridge is W-760, although I haven't tried it with the 170/175 gr. bullets yet. I have three 7x57 rifles, and one, a Winchester Model 70 push feed shot a three shot group from the bench with the 170 gr. Sierra that was smaller than a dime. velocity was 2325 FPS. I know I can load it hotter than that, but that is the velocity the round built it's reputation on. FWIW, the Mod. 70 would not group at all with the Hornady 175 gr. Spire points. It was more like a shotgun pattern. Maybe the #1 and custom Mauser will like it. I thought that if it shot well, that it might be a good load for elk. One thing is for sure. That 175 gr. RN at about 2500 FPS should plow though an elk like an express train. The reason a 7x57 works so well, and has trhe penetration it has is because of the slower velocities that it produces. I forget if it was Finn Aagaard or John Jobeson that said that about it's low velocity and great penetration, but it is true. If you get the idea that I am a big fan of the 7x57, you're absolutely right.

Suluuq,

Nice rifle in a nice calibre with a nice bullet. I have a mauser 98 which I use the 154gr Hornady RN in at 2,650fps.

I have only recovered one and that a quartering shot at 20m range! Retention was approx 65% from memory and an excellent mushroom. The 175gr should do even better.

Thanks for the continued responses, I do appreciate them.
I've yet to shoot this rifle, just too busy to find time. I do pick it up on occasion, and admire it some. I can't help it, I love it! Shooting it will indeed be a pleasure, I'm sure. ~~~Suluuq
