Thought it might be worth a new thread. Pulling back from a higher-pressure 425 grain load for the 45-70 GG, just wondering what you guys might think of the following. I have a new 425 Grain mold coming from Tom at Accurate (his 46-425Q - https://www.accuratemolds.com/bullet...bullet=46-425Q), but before getting another one (his 46-405M - https://www.accuratemolds.com/bullet...bullet=46-405M), wondered if I might get your thoughts.
Reduced loads, both using 1:40. Both, Starline brass. Both, WLR primers. Both, meplat .33. Both, northwoods deer round.
425 grain
Same mold as above so it's gas checked, but I'd shoot it without the gas checks, unless that's ill advised in terms of accuracy. Input welcome). Between 25.6 and 28.5 grains Accurate 5400, for an estimated 1200-1350 FPS/14,500 - 16,200 psi.
New mold, 405 Grain.
Non-GC'ed. 24.5 - 27.0 gr 5400 for an estimated 1225 - 1390 fps/14,500 - 16,200 psi.
Still looking around for good low velocity powders, between what I'm learning here and what's available (or will be available at some point). Just as a starting point, here and elsewhere read good things about the 5400. Whatever the powder, a similar load in the trapdoor range as a milder use of my GG for deer.
