That is a good looking bullet. I am using the NEI #82 and the NEI #76 as my heavy bullets for the Ruger Blackhawk, both are gas check bullets. My Blackhawk cylinder measures a rough 1.7450” long overall.
My #82 bullet weighs a nominal 122-grains ready to seat. The #82 bullet is .709” long and I use a COAL of 1.5650”. Cast from my soft mix the #82 bullet weighs 130-grains lubed, checked and ready to seat.
The #76 bullet is more of a traditional SWC bullet and is .783” long without the gas check. I use a COAL of 1.580”. This bullet weighs a nominal 125-grains and 138-grains lubed and checked, ready to seat.
I am sizing both bullets in a .313” sizer; my cylinder throats measure a little over .312” using a ball gage.
I am able to push the gas check bullets well above 1,300 fps in the 5” Blackhawk but have been thinking about a heavy plain base bullet for the heavy frame 327 Federal revolvers. 1,200 fps is a good velocity for heavy bodied raccoon and porcupine as when shooting up into trees I want the bullet to remain in the body but penetrate a shoulder if I can work the angle.
