Karl-Erik45-70 velocities
Hi!
I wonder what velocity you can get from a 45-70 built on a Ruger no1 with 350 grains and 400 grains bullets?
I have seem that they load that caliber in Ruger no1 to 2100 to 2200 fps.
Best regards
Kalle

David AthertonI can only answer for the loadings on a Marlin. This of course has a limited pressure of 40000 psi. I can get 2190fps out of a 350gr. Hornady jfp over H4198. I shoot a 405gr. JSP rem. at 1940 with of Rel. 7. Rugers tolerate another 10000psi of pressure which translates into a few more grains of powder

meteThe #1 is of course capable of very high pressures . The limiting factor is the case . The 45-70 case is much thinner than the 458 case. The other problem is the bullets ,they are usually designed for the typical 45-70 velocities. The 350 Hornady driven at 1800-2000 would be very potent on swedish moose, I wouldn't drive it any faster.

4X4SNEAKMy Hornady 3rd edition lists 2300fps with IMR 3031(59.6) and their 350. They list 1800fps with their 500 and IMR 3031(53.1).
Steve, hows the weather up at the old Glasgow AFB?
