The title says it but, hypothetically, if one had several different alloy makeups and all had virtually the same weight and bhn would/could the INTERNAL ballistics be any different? Talking all other things being equal and perfect gun and perfect shooter. I am and have neither.
Examples,
Alloy 1: Electrotype 95/2.5/2.5 BHN 11
Alloy 2: 6 pounds pure + 0.5 pounds Pewter 92.3/7.12 sn/0.46 sb/0.12 cu This is assumed obviously as pewter makeups vary. BHN 11
Alloy 3: 11 pounds pure + 1 pound tin 91.7/8.33 BHN 11
Alloy 4: 96/1 sn/3 sb BHN 11
I'm aware from testing that TERMINAL ballistics will be different. I'm only talking about the INTERNAL ballistics here.
Also, I personally doubt I'm a good enough loader or shooter to test this myself furthermore it would take way more components than I'd like to expend to make any test statistically meaningful.
Thoughts?
