Loads for 390 Grain Gas Check 458 for 45-70
Hello Folks:
Just wondering if anyone has done work ups on a 390 grain Gas check bullet for 45-70.
Just recieved 200 from the bullet barn and want to work up for a Marlin Guide gun in 45-70.
I can start low with 405 grain numbers as the design is close, but just wondering if anyone has done this for this weight?
