Sent a few downrange today.
PPU 150gr were doing 2608 fps in the 16.5" Bergara, same ammo did 2734 fps from the 24" Brno. Not a lot of difference for a third less barrel length!
8 grains of Trailboss had Robert's 151gr cast bullets doing 1089 fps, about the same as 7.5 grains does in the Brno. Different twist rates (1:8 twist vs 1:12) may be the difference. 8.5 grains gave a mix of sub and supersonic.
The PPU 180gr factory ammo did 2393 fps.
