I have really been stuck in the zone of getting a old military gun to play with. Another idea I had after coming across some great buys on Remington Rolling blocks that look in great condition but with odd calibers would be to convert one. Does any one here use one of the old Remingtons and how much will they stand up too ?

While the idea is cool, and I wouldn't mind having an RB in some cartridge like the 9.3, I'm not sure the action would stand up to the strain, even if made from the best of modern materials. Then again, I could be all wet.
It'll be interesting to see what others say, but I don't think any of the original actions are up to it.

I have a Lone Star 45-70 and they are beautifully made.Those are made in 30-40 Krag for example which is loaded to about 40,000,pressure and I don't think Lone Star would recommend higher than that.According to the NRA 'Gunsmithing Guide' a #1 Smokeless RB action can be chambered in such cartridges as 250 Savage, 7x57, 6.5Mannlicher. So the 9.3x62 might be pushing it for an old action.

It looks like the biggest ones are 45-70. I did find one in a origional chambering of 7x57 so that seems like fun in a origional caliber that was popular on the dark continent. I don't know why but theese always conjur up images for me of ....Dr. Livingston I presume .

I have a No. 5 repro. on order at Lone Star, and he and I are tossing back and forth possible chamberings.



First off, I'm pretty sure he doesn't offer the extractor for the rimless cartridges on his reproductions. Second, he has set a pressure limit of 44,000 psi (piezo) for them, and I'd like to stay a bit below that. Oddly, he's not too worried about case diameter at his pressure limit; I wonder, though.



Phil Sharpe wrote he thought the RB good for more pressure than usually granted, this based on some proof tests he did on an original 7mm. I still prefer to keep the breech thrust down, if for no other reason than gas handling is not up to modern standards.



I'm not sure what he's willing to do with a re-worked military action. The 9.3x57 might do from a 7mm. Give him a call; I've enjoyed talking with him.

Chuckwagon. Be advised that the original 7mm rolling blocks apparently used different headspace dimensions. ket waters brings this out in his load data for the 7x57. He stated that he read it somewhere. I found his source ina sidebar from an American Rifleman magazine printed sometime in the late 1940's, IIRC. The reason Remington did this was unclear, but it's something you have to look out for.

Have been told the 7mm was done this way, due to the habit of the troops not cleaning the weapon, most of the south anerican models seemd to be this way, have not seen one of the French 8mm lebel models they did just before the war, I have had 3 or 4 rollers and the largest chambering I had was 45-120, and it required some work on the hammer to feed the long round over the top of it

"asdf" beat me to the 9.3 x 57. It is probably as hot as you want to go. When Rbs are shot with too much pressure the rim will become angled to the centerline of the case. This is from the breech block rolling back just enough to allow the case rim to stretch more on the top than the bottom. When bad enough you can roll a fired case on the table and see the wobble. This didn't direcly answer your question but if you go with the 9.3 x 62 you can avoid overloads by checking this on your cases.
