Title: AT44-10 accuracy
Post by: Stefan on November 27, 2011, 02:58:07 PM

After tinkering with it - re crowning the barrel, replacing the o rings on it, adjusting the trigger to 1 lbs pull, and finding out which pellets she likes the most, these are the first results.

great work Stephan. Maybe I'll try re-crowning the barrel on my little demon-seed Pneuma. Either that or sell it to raise funds for an old FX2000.

Stefan, what yardage were those groups shot at and what pellet (speed also if you have it)?  Also, what do you think made the biggest improvement to your rifle from your mods?

Thanks Darryl. If you know a gunsmith with proper tools needed, do the re-crowning, I think it will help a lot.

Groups are at 36 and 57 yards, measured with rangefinder, with 11 degrees incline.

I don't know which one of the mods helped the most. Light trigger itself is a great improvement. The old crown wasn't bad, but I like the new one more :D. Having a custom hammer spring (same strength, but less coils), deburring the tube and polishing the hammer itself, that probably isn't it.
JSB heavies - 18.1 grain are the pellets. Speeds - around 890-900 fps.
