.22 Ultra Se Single Shot

[witty 7]

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

Must say that's some really consistent shots there power wise, those little ultras are cracking!

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
