Peter, I really need to come out one day and check out the Impact. On second thought, maybe I shouldn't. LOL

Guarantee you’ll want one after you shoot mine. Mine has been highly modified by myself and the last thing it’s waiting on is it’s new 25” TJ’s barrel to finish everything up. Peter
Michael ... indeed you get more poppet lift and a tad more dwell when the poppet gets off the seat easier ... you did TWO things in achieving that, Peek and the reduced diameter / area of the poppet itself.
Mike. I am not too clear on The barrels twist rate you did the report on. I know it's not 1-14...so is it 1-17.7 or 1-18? You mention MP mold that has a driving band at .254...that's the exact mold I have for my Huben .25 cal. but it's not performing good right now as dropped cast. Do I need to size down to .250?
Those should be fine in a 14" twist.... and TJ's has a 0.250" groove 0.243" land (ACP) barrel with that twist rate.... Does he use the same profile and LOA for both the .22 and .25 cal bullets, and just interpolate (spiral) it out to the larger diameter?.... I notice in the Spec. he mentions .243 - 6mm as well, which leads me to think that is what be may be doing.... Bob

What I should have said is NO "It Will Never Shoot Well"! Garbage mold. Sell it to me. P-L-E-A-S!!! Still out of Stock there. GRRRR!!!
