On my 2289g I have seen 605fps w/ 14.3gr pellet @ 18-20 pumps (can't recall). That was right under 12FPE which was impressive. However, I decided that the 2289g (especially with a silencer) is too long to be a bugout gun. I am now more focused on what I can get our of 1377 and 1322 with stock barrel length.

I just got 579fps/10.64fpe on a stock 10.1" barrel at 15 pumps...posting in pump up the jam thread with chrono

What pellet?

I think I saw well over 500 w/ my stock 1322 and 14.3gr pellet with a few over pumps...can't recall but it was no more than 15. BUT definitely wasn't 579fps...maybe 530 or so.
