RE: T/C Hawkens
The standard 50 cal maxiballs weigh 370, but there are other weithts. My brother used to shoot the 460 gr maxiballs. They were awesome on deer. The maxihunters also come in several weights, but generally weighless than maxiballs.
Maxihunters never shot well for me. Tried about 10, and recast the other 10 into maxiballs. The front or top band on these bullets, that is supposed to engrave into the rifling, is much smaller than the top band on the maxiballs. Maxihunters may even be a bit smaller diameter, seemed that way to me at least.
I have never seen a T/C Hawken or Renegade that wouldNOT shoot a maxiball over 80 - 100 gr powder very well.
