theyre targeting them at the high volume shooting calibers.

im sure given time they'll get more mandrils and offer a few more options. if i were to speculate 308 and/or 6.5CM will be next

I just picked up a Bear Creek Arsenal 18" side-charging 450BM upper. Put a competition brake on, cleaned the bore, and headed to a close 50-yard indoor range. Shot 20-rounds of Hornady Black and 5-rounds of Barnes Vor-TX. It would stack the Hornady Blacks, with 6 shots into a 1" square at 50-yards. It sprayed 5 shots of the Barnes into a 6" square. Definitely did NOT like that round. Zero FTF or FTE and fed fine out of both Duramag and ACS mags. I did run a scope down the barrel and what I saw reminded me of looking at a Savage barrel. Savage has taught me not predict accuracy by the way a barrel looks though, and this one shot really well with the Hornady Black ammo. I know QA/QC has been an issue with BCA, but it appears I got a good one, at least as far as I can say after 25 rounds. I will likely just stick with Hornady Black as I'br put down plenty of deer with FTX muzzle loader bullets. I have no trouble recommending BCA uppers based again on limited experience
I really am digging the side charge too.

Purchased a BCA 16" side charger about a year ago, accuracy is good for what it is, feeding problems and such had me taking it to my Gunsmith, he declared it badly over gassed with my Primal 46. Solution was a reducer insert for the gas tube. Need to get it back to the range for more testing. The suppressor makes a major difference in recoil.
