My buddie built a 45 cal smokeless for me just before hunting season this year.
Haven't had much time to put many rounds down range but what I have has been very good.
Did take a doe with it at 300yds.With a heart shot.
Was hunting my box stand on a power line and had my ear plugs in because of the break.It is pretty loud
First day at the range with it took a couple shots to get it dialed in at 100 yds.
Guessed at how many clicks to go for 300 yds, wasn't to far off.
