I had a mould made by Hoch to cast a 350gn bullet at .4245 and I size to .424. Of course the more Pb in the mix the heavier it is and the 50/50 (ww/Pb) bullet drops at closer to 375gn. I have used from heat treated 90/10 (ww/lino) over 87gn 2209 for 2416fps (88gn 2437), straight lino over 83gn 2209 for 2300fps and exceptional accuracy and 74gn 2208 for exceptable accuracy and 2365fps.
50/50 (ww/Pb) over 63gn 2209 for 1900fps is the accuracy champ and a 50/50 (ww/Pb)over 21gn Red Dot is a great plinker. All except the plinker use cu GC while the plinker uses my own made Al gc. All load testing at 55 yds with aperture sights. A 70/30 mix of ww/lino at about 15-16 BHN would make a good alloy for the heavier boddied animals but the 50/50 (63gn 2209) at 1900 would still make a good 100-150 yds killer and even my 50/50 bullet plinker load at 1500fps has bought a number of goats to the deck.
