I shoot a Knight muzzleloader and just started using BH209. I want to try the TMZ's. However, I want some tips on which one to try first. I don't want to have to try both if I don't have to. They are quite pricey$$$. Which bullet is likely to give me the best accuracy out to 200 yards. A friend gave me a Barnes TEZ to try, but it seemed a bit too easy to push down my bore. My bore diameter is .5015 - .5020. I have heard that BH209 needs a fairly tight seal to be at its best. Any suggestions are appreciated. Thanks.
