I've been pumping this week. No big deal. 2 mags takes me from 300 bar to 200 bar on a .22/350mm setup. About 10‐15 minutes of pumping or so for that 100 bars. OK hunting, not so much for tuning.
Happy to say took my first kill first shot this morning my first time out with the L2. It was the .22 with 350/150mm Tishina. Gray squirrel at 40 yards, headshot, 18.1 JSB, DRT.
