Ken: I'm completely stoked on the performance of my Pac-Nor SS Super Match 11 twist, 3-groove poly barrel. I built that rifle primarily to shoot the 39gr SBK and the Nosler 40gr BT (will try the 40gr V-Max eventually, have 600 on hand). To that end, it loves both the intended bullets, but in honesty, I have not tried any 32's in it, as I've got two other 204's with 12 twist barrels for that weight bullet. So I cannot comment on the performance of that barrel shooting the lighter bullets; sorry.
Would I do it the same again? In a heartbeat, "yes". Accuracy is outstanding, and the long range performance of the heavier bullets is well known. I'm also glad I had my reamer ground to my specifications, as now I have the beauty of a tight neck chamber with no neck turning, and the brass from this chamber should last far longer than brass fired in any SAMMI factory chamber. Sort of the best of all worlds. Order that P/N barrel with confidence for your Brno, you won't be disappointed.
Which one did you go for? I'm ready to order now for my BRNO 601. Thanking you, Ken.
