I recently did an flat hop and tight bore barrel upgrade on my gun.

Hopup off and .2 gram BBs my gun was shooting an average of 404fps

Hopup on and .3 gram bbs (which is what I actually use in the field) my gun was spot tested and came in at 296.

I was stunned, should going to .3s and putting on hop cost 100 fps or do I have a leak?

Any advice would be appreciated.

(p.s the gun is def more accurate and I think shooting longer than before the mod so I may just keep it as is even though it's low fps is disturbing.)
