RE: TC Maxi hunter or Maxi ball
Hi Strutter, for what it is worth if I am killing paper (which is about all I have killed nowadays) the maxiball really is more accurate than the maxihunters. I know they load a bit harder and are weird looking but those lube bands do their job and the bullets shoot great. That being said let's look at what you are shooting them out of.
A Black Diamond has a fast twist rate so if you want to try the maxiballs go with the heavy ones not the light ones a "long" bullet will work best in your rifle. I would say the same thing if you wanted to shoot Powerbelts go with the heavy ones the 295g ones are made for the 48 twist rifles.
T/C use to make not sure if they still do a 420g .50cal maxiball that shot great in short barreled fast twist guns. Just make sure you don't go with the max powder loads because the gun can handle it but it is murder on your shoulder.
If legal where you live a 250-300g sabot should work fine in your rifle.
