yep...still have a few from when H and Co were CO based.
used them on 6.5 and 30 BRX and 375BR uppers.
hadnt run bullets that heavy yet , mostly Speer TNTs .

I built a few for guys to do subsonic work with , 180 Bergers at 1050 fps , quiet as a mouse through a 30cal can.


tell be about that 30BRX what performance do you get from a 150gr?
