Gunner, couple of oddball parallels that perhaps illustrate the benefit of tin in the mix. About 20 years back I was on a quest to make a 77/44 shoot well, and along the way picked up a copy of Paul Matthew's "The Paper Jacket". Well, you know where that led.
The bullets are 300 grains, pure lead.
8 shots, 100 yards with a red dot sight. THEN I adjusted for zero. The ammo had been loaded in 2002.
Splat Factor: 10
Retained weight ~294 grains
I've shot pigs and deer with it, they don't take a first step after the pull of the trigger. None of the shots have exited so it's not a five-fer load, but it damn sure ends the parade. I have a couple hundred loaded, just in case.
The go to bullets for Thumper along with some Sneezer fodder:
My .45-70 load with neighbors, second from the right. The .44 is 3d from the right. Big one on the right is my truck gun load.
