Home Forums Hunting & Shooting Express Rifles and Big Bores Only 458 x 1.8" for Michigan deer hunting in Zone 3

I use them in my Ruger No. 1 .45-70. I use standard RCBS dies & seat bullets out to same OAL as 400 gr. factory load. I've used 400 gr & 350 gr Speer bullets. Seating the bullets out you have virtually the same powder capacity so I would think any book charges could be used. For my purposes, deer at 100 yds max, I don't have need to hot rod it so I use a mid range charge of 3130. Using it in a single shot I don't worry about a crimp, so not sure how well they'd hold up in a tube magazine. Being the same OAL they should feed okay.
