#Tc hawken 320 grain maxi ball full#
I also found that over time, if decent accuracy was to be maintained, a FULL cleaning program was needed. I found accuracy to be OK out to about 100 yds. I found that even the pure lead Maxi would fully penetrate most anything walking. I used near pure lead and charges of about 90 gr FFg in the 1:48 TC 50 cal. They (TC) always recommended very soft alloy for the Maxi to help ensure that obturation. Inertial obturation of the bands into the lands at powder ignition would give enough engagement into the rifling to rotate/stabilize the bullet. It could be started with finger pressure to that top band then started with a starter then rammed the rest of the way with the long rod. It is designed to be right at bore size on the bottom drive bands and be slightly larger than bore on the thinner top band. The theory by TC when it was developed was to provide a heavy conical for hunting using fairly heavy charges. The bullet by the way is devastating on deer. It does work as I've recovered many and saw the proof. When the powder burns and the pressure hits the bullet it tries to move it and what the bullet does is try to stay stationary and the pressure compresses it, obturating it to the bore/groove.
This makes it fairly easy to seat atop the powder. Starting from the base the first two are bore size and the one near the nose is almost groove size. The Maxi-Ball has three large bearing bands. More so than a wooden ramrod, given the large bearing surface vs. If I'm right, it would seem to either be greatly undersized and ergo just rattle down the bore, or so oversized you'd need a hammer and long ram to get it down the barrel. I grasp the idea of a minie ball undersized, the skirt opens up on firing.īut how does a maxi ball work? If I'm wrong and it has a hollow base, great. It was my understanding that a maxi ball is like a regular bullet- flat bottom, conical shape.
