Personally; I don't think that the 230Gr Ball ammo would be the best choice...
A 200gr Lead SWC that deforms and loses kinetic energy when it strikes the ground under the bike might be a little bit safer... :thumbup:
...Unless you use Speer's 200 gr "flying ashtray"! :bowdown:
John,
Would you want to try using tracer rounds in that Garand for opening up those eight holes??
