So I went to the range today and tested a few rounds out. All seemed to be fairly low pressure compared to the 3" turkey loads in terms of recoil and report. Those gas seals picked up about 100 fps without modifying charge weight at all.
35.0 grains
300 MP.
Chronograph didn't read but powder didn't burn completely and report and recoil weren't all that impressive.
The bullet skipped up the hill about 200 yards and was found lodged in the snow and ice after about 4 skips. Velocity couldn't have been more than 550 fps.
30.0 grains
Alliant Blue Dot
950fps.
Report and recoil were definitely "shotgun-like" and the bullet could be heard audibly passing through the air and the impact with the target board sounded like hitting two wooden baseball bats together.
20.0 grains
Unique
865 fps.
Similar to above but with less recoil.
