I think everyone focus's on .22,not the expanded width after impact...You show me penetration for your .50 round ball into ballistic gel that exceeds 16"...Show me....

This is 5 Federal Fusions(.223) shot into ballistic gel and penetrated 15" with an expansion to .54 caliber.The .458(out of a 450 Marlin) 400 grain Swift A-frame only penetrated 17".

Show me some data on muzzleloader penetration depth with a .490 ish round ball.
