I think you meant to say accuracy is NOT related to barrel length to any appreciable degree.... If using iron sights, a longer barrel gives a longer sighting radius which adds to more accurate AIMING, but barrel length, more than the last inch being straight near the muzzle contributes virtually nothing to accuracy....

Yes missed the "not" :roll: :lol:

X2 on the sight radius being increased and increasing aiming ability, but even with the "the best aiming on earth" it still doesn't affect accuracy in any definitive way. I was extremely surprised when I originally found out how short the TX's barrel is, but its performance and accuracy have obviously spoken for itself many times, worldwide...

if you test it with a chrony you should notice a small augmentation of fps from 14" to 18" but after that your valve dosen't provide enough air to keep accelerating


hi guys.. just an update, I put a 24 inch barrel on my 1322 with ftp and its only shooting 479 at best with the crosman hollow points at 10 pumps.... gonna throw back 14 inch barrel and see it there's an improvement because I was shooting faster than that with the stock valve and piston with 14 incher... just gotta wait till sunday till I can use a chrony..

I'm getting really tired of people quoting stuff they read on the internet as gospel.... How effective a 24" barrel is at increasing the velocity is relative to how much power the gun is producing.... If you pump a 2289 three times you may not notice a difference, and in fact the 24" might be slower.... By the time you have a 13XX or 22XX shooting at PAL velocities, I can almost guarantee that the longer barrel WILL increase velocities.... By the time you get up to 700-800 fps the difference between an 18" and 24" barrel may be close to 100 fps....

I'll give you a hint.... If your gun is noisy, adding a longer barrel will increase the velocity.... The muzzle blast is proof that there is still enough residual pressure that a longer barrel will make use of it.... The noisier it is, the more advantage there will be.... My experience with the 22XX series is that velocities keep increasing with barrel length up to 24" on CO2, even with stock valve.... although on a stocker the increase from 18" to 24" is relatively small (20-30 fps)....

Hey, Bob, just wanted to get back on the Internet to respond to you :P . If your first comment was a reference to my post, I must confess that most of those comments I referred to came from this very little part of the Internet. As for the closing comment, I guess we were all assuming that no one would push these pistols to PAL levels, making them restricted weapons. So I guess you supported my point with your closing line.

I guess if you consider 20-30 fps to be "no relevant improvement", you proved your point.... :roll:

I've actually TRIED this and found that a 24" barrel does shoot faster than an 18" on a stock 22XX, on CO2, not just read about it.... YMMV, of course.... :mrgreen:

Actually, Bob, so have I. :wink: But, I say again, as I've said before, I would never even think of challenging your expertise. I just thought you were being a bit harsh in the way you presented it this time.

Peace.

Thanks guys. I think 'I'll get over it. So many dreams yet to be crushed...

So much hope I could lessen my fantasy burdens here...

So many too burdened by their own fantasies to bother crushing mine.

I appreciate the sympathy, however.
