1" group at 30 yards ?

[cosmic]

Just wondering about my evanix hunt master pistol.. I received a .22 and a custom .25 conversion for it.. The .22 shoot about 3/4" at 30 yards.. The .25 shoots 1-3/4" at the same.. Is that good for the 10" barrels.. I have only 2500 left in my nitro tank and was wondering if it would improve with a higher psi...
                                       Thanks

What pellets are you using ?

Tried a few but in the .25 the polymag, eunjin 35.8 gr, and the H&N silverpoints seem the best.. In the .22 the newboy hollow points and polymags along with the ultramags seem the best.. I wonder if the fill pressure has a greater effect with the others I have tried.. I have shot in the .22 Crossman destroyer, premier beeman crowmagnum,eunjin 28.5 gr, .. In .25  jsb jumbo exact kings 25.39, beeman Kodiak match 31.02gr, H&Nbaracuda 31.02..Maybe a higher pressure would tighten them up.
  Some of these seem loose in the mags..

doesnt sound too bad but id think it would be a little bit better then that.  I havent had that much trigger time but my prod will do dime sized groups at 25 yards, so thats prob 3/4 inch?

What's the conversion like? Drilled out magazines and new barrel? What kind of fpe are you getting?

I believe a drilled out mag and it seems one hole is a bit deeper than the rest.. Not sure if the barrel is new or a modified one from another gun..  Fps at 2500 psi 800's, 2200psi upper 6 to 700 fps.. I do believe when I first had it at around 2850 psi it was running in the mid to upper 900's.. Should have tested it then..
