Probably not. A quick look at "Load from A Disk" shows even with the mildest loads, you'd be over standard .45-70 pressures. Perhaps with BP it might be ok???? Hubert | |||

450 #2 is about the same pressure as the45/70 max load, but the bolt thrust would be higher.. bs.. it's a 7# gun.. not even a recoil junky will hot rod it much jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I think that this was discussed in great length before. I will recap it as I remember it. This little idea struck me as a fun project also. I think the the general feeling was that it was safely possible as this action is used for a 30-06 chambering also. However the weight of the rifle seemed to make most say that it was not worth it unless you just liked painfull recoil. The main problem that I see with this project is getting one of these rifles to begin with. | |||

I beleive that PWN375 of this forum coverted his 45/70 Pedersoli hammer double rifle into a 450#2 NE. It seemed to shoot well and required no re-regulation. He did describe the recoil of the light rifle as "Brisk"! Rusty We Band of Brothers! DRSS, NRA & SCI Life Member "I am rejoiced at my fate.

As long as your ammo doesn't develop over 28K PSI! My feeling is that the "action" would not be the problem, but rather the thickness of the barrel walls. There's a lot more meat in a .30/'06 barrel of the same O.D. as their .45/70 tubes. In addition, the big fat case head of the .45/70 places the stress on a much larger area.

For the price I would just use one in 45-70 as it is. The gun does not have ejectors and it's going to kick like heck even in 45-70. I see it as a real fun gun that might need a better pad and trigger work. Join the NRA | |||

Here's the calculation for thrust against the face comparing the 45/70 to the 30.06. 45-70 (.608 Rim) .302*.302*3.14159*28,000psi = 8,022 Lbs force of thrust 30.06 (.473 Rim) .2365*.2365*3.14159*60,000psi = 10,542 Lbs force of thrust You should be able to load the 45-70 to 36,000+psi to get the same thrust as the 30.06 on the breechface.

Yes! BUT my concern is not the thrust on the breech face so much as the thickness (and composition of the steel) in the chamber walls - the question is, "is the chamber strong enough for that pressure level using a case of the diameter of the .45/70??

is it a better idea to make the 30-06 one into a 375 or 411 hawk??? 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S. (Founder) | |||

I was in Walmart yesterday and saw some Sparton single shot shotguns. It may not be too long before the double rifles come out. My biggest concern after owning a Baikal stagecoach gun is the triggers, They were so bad it took all the fun out of playing with it. Literally a 1/2" of creep in the back trigger! I plan on looking at a 45/70 when they hit the store shelves, But I wouldn't order one sight unseen.

What would it take to make a .30-06 baikal into a hawk .375?? Is it just a matter of reaming out the bores like a .338 or would it require much more serious machining??  Please edjamakate me!I picked up the baikal .30-06 cheap and don't plan on changing it anytime soon but I kinda like the idea of a .375 built on .30-06 brass! H.

The biggest disadvanatge to rechambering either the 06 or 45-70 is the thickness of the barrels. The 06 might have enough wall thickness left to be rebored up to .338 but the 45-70, forget it. I measured the wall thickness at the muzzle and it was approximately .045! After 2 shots from each barrel it was to hot to hold.

It would be very simple to rechamber to the 45-120 (aka 45-3 1/4). You can headspace on the rim recess, and dies are reasonable priced. Rich I am building a SS in this cartridge | |||

the gun is too light for using 450 NE loads ... even for ME.... gentlemen, I've had the 45/70 .. its too light to do this with opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Thats what I thought as well. It led me to thinking (dangerous idea, I know!) that the ought-six bored out, using the ought-six brass would be a much better idea. I twoul leave all the barrel thickness around the brass intact. H. Cole Stage III, FRGS ISC(PJ), USN (Ret) "You do not have a right to an opinion.
