My roundball guns were two TC Renegades and a New Englander. All got FFg Goex and #11 caps. 100gr charge w a Hornady .495 ball w thick cotton patch.
New guns required at least 50 shots to stop vertical stringing. At about 100 shots there were golden.
Lost my target in a move.............had cloverleaf of 3 in the X at 100 from the bench (New Englander).
Only shot one deer with it, a decent 9 pointer on the trot at about 35 or 40 yards. Hit him where neck meets shoulder, coming in. Bullet went through both lungs and stopped in hide behind shoulder on opp side. Still have the bullet smile

Cheaper gun IMHO, liked the Renegades better.

Bought a .54 Renegade .with killer wood about 3 yrs ago from a buddy. It was like new.
Gave it to another buddy that wanted to get into MZ hunting.
Told him to try roundball in it (keep recoil down).

Still entertain ideas of a reg Hawken, my SE, a Cougar and a Supreme..........get four and hang em on the wall.
Buddy has a Cougar he doesn't use, keeps asking me what I want to trade for it.
