Hello im ed from holland and new to this forum. I ve owned many airguns and now own an impact x in .25. The reason i bought it......i love a bit of tinkering and this gun lets me do it all without opening it up.
i ve got both the 600 and 700 mm barrel. And am bussy testing both. Its still to early so have any definetive results but so far i ve been having mixed results. Right now i been using the 600 mm because the 700 gives me to much speed with the 700 mm barrel. Of course i could tune it down but im getting incredible consistent shot strings on the current setting. Max spead of 5 feet per second. With the 600 mm barrel its now spitting a 25 grain pellet at 920 fps..... looking at my groups i think its to high
t
this is at 110 yards 100 meter.
S
same distance.....i get 2 or 3 that land just perfect and then 2 or 3 that land 1.5 inch away.....dont yet know why.
it is however very consistent. I plan to shoot 34 grain out of the 700 mm barrel. I have already tried the 700 mm barrel at 850 fps.....with about the same results as above. Wich i dont get because it should be the right speed. Hammer is on 3 and valve at 3.4 ish. For the 25 grain pellets.
So what i plan to do now is try all speeds from 780 to 950 fps for both 25 and 34 grain pellets in both barrels and then tune the gun for the prefdered speed with as little reg pressure as possible......this might not be a great plan since everybody seems to crank it up to 140 150 bar....but so far i seem to get very high speeds at the current settings. The 25 grain does 950 out of the 700 mm. Wich suggest to me the reg can go lower....might be wrong we ll see. I plan to post my results in this topic....there are may options though.....could get a low speed with high reg pressure 2...... cant wait to do more testing....keep yall posted
