Built it for longevity with a solid pump cup piston with felt wiper and brass valve.
Does 490 as is. If I push the pellet forward in to mimic a long bolt probe it does this at 10 pumps. 14 inch barrel cut down to 12 and recrowned
. I can get 1 ragged 5 shot group two handed at 10 yards.
I can pump for more fps but that's the role of other builds.
Long bolt probe going in tonight.
