1910 rolling block strength

madeintheshadeguns

Hi, this is my first time using this forum, and I am not sure if this is where to ask, or if I am rehashing an existing question? I have a remington rolling block carbine model 1910 in 7mm mauser. It has been altered ( forend shortened ) and the barrel is not servicable. I have allot of experiance rebarreling mauser actions, and have rebarreled a few other type of weapons.My concern is not in knowing how to rebarrel, but if the action would be able to handle the 375 winchester cartridge. The data I have shows the 375 win at about the 48,000 to 50,000 cup range. What is the accepted pressure range for rebarreling this rolling block? Any help would be greatly appreciated.[:)]

The one I had even though in excellent original condition, had to much spring in the action. All the 7 X 57 loads I shot in it including my light handloads had incipient failure, (stretch marks) just forward of the cannelure.

Unless the action your going to rebarrel will lock up a lot tighter then mine did, you will only get one shot from each brass case. No way was I going to reload any of those case with stretch marks.

I had previously had a very bad experience with one of the World War I French Rolling Blocks chambered for the 8mm Lebel cartridge. I was firing some guys reload when a case head let go and I got a bunch of hot gas in my face.

Ugh, too much.
How about a traditional .38-55 at 30,000?
Remington (and Lone Star) made them in .30-40 Krag at 40,000 but I don't know how well that would work in a well worn specimen.

I have seen pictures of demolished Rolling Blocks. Rufe was lucky, the design does not handle gas very well. One source said an overloaded Trapdoor was less likely to actually hurt you, even though the Rolling Block is much stronger... until it isn't strong enough.

I would use a .38-55 reamer to make a .38-55 rifle.
The .375 Win is somewhat larger in diameter. Considering that the bullet is smaller, that means the brass is specified thicker. No physical reason not to cut a .375 Win chamber and load it light. But what happens when you trade it off?

Eastbank has a point. I think Remington chambered some Rolling Blocks in .30-30 so it would be an authentic configuration and that would sure simplify the choice and availability of barrel and ammunition.

thank you for the information and input. I was thinking the 375 win would probably be too hot for this action. The 38-55 would be a logical option considering it is so much similar to the 375 win in dimensions, but not loaded as hot. Next question I would have then is could a 375 win chamber reamer be used to chamber a 38-55?? any thoughts? Thank you!![:)]

Thank you hawk for the input. I will aquire a 38-55 reamer. I really apreciate you taking the time to answer my questions.

another two shells maybe to consider a 32-40 or 30-30 winchester. eastbank.

+1 on the .32-40, low pressure,very light recoil, extremely accurate.

when you rebuild your r.b. make sure the 2 main 'pins' are a tight fit. it is easy to make new ones
