witty 7 Posted June 16, 2013 Report Share Posted June 16, 2013 hello all, got my first pcp yesterday a single shot bsa ultra .22 new version comes with a bolt rather than the mmc.... read so many different reports on shot count, fill presure etc so i did a chorno test with aa 16 grn pellet could any of you guys let me know if they look good, bad, average think i have seen somewere that bsa have shortend the air cylinder ? from recomended 200 bar fill (used hills pump) shot fps 1..........560 2..........560 3..........561 4..........560 5..........557 6..........561 7..........562 8..........562 9..........561 10........562 11........565 12........561 13........560 14........558 15........558 16........560 17.......556 then drops 2 fps (abouts) for the next 10 shots... check presure down to 90 bar so about 27 shots ??????? also when i fit silencer and chrono it fps drops 552/ 555 is this right ???? would filling to 210 bar give me a few more 11+ ft/lb shots or is overfilling not advised any advice very welcome thanks Mark Quote Link to post

Mawders 595 Posted June 17, 2013 Report Share Posted June 17, 2013 Must say that's some really consistent shots there power wise, those little ultras are cracking! Quote Link to post
witty 7 Posted June 18, 2013 Author Report Share Posted June 18, 2013 morning thanks guys thought i got a lemon from shop..... i think this new bolt version may be different from mmc version air tank look bit shorter maybe inch and half and seems shoot fine from full ?? rather than 190 fill . did a shot count last night from 200 bar fill (hills pump) only at 10 yards got 30 before poi was dropping checked and it was down to 85 bar (last shot 8.4 lbft) so maybe 25 is magic number which is fine if it sounds about right to you guys with the silencer fitted should it drop in power slightly as it controls the air behind the pelet ????? sorry for all questions new to the pcp side thanks Mark Quote Link to post
