Title: 45-70 loads
Post by: BrandonWatts on November 18, 2020, 07:02:19 AM: I recently received a Thompson center encore frame rifle, I ended up ordering a 45-70 barrel for it. I have always loved the 45-70. I also ordered brass, dies and some 325 ftx hornady bullets for it. I am just looking to see what you guys have for load data for the 45-70. I’m not really looking for low pressure loads, not to concerned with recoil of the rifle either.
So what do you guys got for the old cartridge? I have seen some load data for h335, imr3031, h4198 and imr4198. Out of those powders the only one I have is h335.but could get my hands on other powders if I need to.
Thanks

When I was researching I also found:
The Hornady factory FTX load is supposed to be 49.5gr of H4198, but I cannot confirm.

IMR I have two loads written down, 47.5 and 46.7, but have not tried them.

Reloader 7 I found a starting load of 43.2 and a max of 51.5. Post said that 48.1gr had exactly 2000fps for XLR.
51gr was giving another poster 2070fps in a 1895GS and another 51.8gr for 2000fps (no weapon listed).

Disclamer: I cannot vouch for any load other than the 48.6 of H4198, which I have fired from a Rossi Rio Grande. I did not see any high pressure issues.

I tried some loads with 3031 and h335. I liked the H4198 much better with the 350's. super consistent powder.

Yes, I recall the loads being stout in my guide gun.
