Cutting Barrels, Tips and Rules

Dears,

i don’t know if we have talked about this, i just wondering to know more about this, how someone can cut the barrels ? what is the tips and rules to be considered for cut off the barrels?

or, it is simple, we can just cut the barrel from which point that we like/want?

in fact i like to read some info about the barrel types and rifling as well…. lets share all info that you guys have,,,

thanks for the reply

What’s the typical choke down and choke length for a PCP barrel? Are they the same for all calibers or does it vary?

DT

YES, and they also need less energy/air to push pellets out ……. much more efficiently.
So with the same FPE out but gaining a higher shot count will be an added luxury with the choke-less.

But the negative would be a very temperamental barrel that likes a certain pellet batch/lot with a speed dialed in for each …………

……. without no pain, you have no added gain.

Guys….

So..all of us heard that chocked barrels are the best….but i had conversation the TJ barrels with Ernest …he told me that TJ Barrels are not chocked but they are very accurate. ..

I don’t believe they are any rules to cutting/mod a barrel, the front or the back end.

IIRC there was someone that cut a small % portion or length off of the choke/front end to send JSB Kings at 1025 fps and retained a very good stable flight accuracy ?

Like numb nuts said, choked barrels need to be shortened from the breech end.. between cutting threads new transfer ports chambers /pellet leads, crowns and internal breech o ring grooves it can be quite involved. A mill and a lathe is required to do a good job of it.

Nonsense ! A real man does it with a hacksaw, Dremel and some fancy filing. What do they teach you over there ?? 🙄

😯 I thought that post was going to end badly!

Freemanshooting on youtube has a video where he re-crowns the Cricket barrel, maybe that video has some tips? At least about crowns

Wing, I see you got Ville’s name right………………………..numb nuts. :rofl:

Just make sure you cut it/ re-machine it from the breech end or you´ll be sorry … The muzzle end is choked and if you chop the choke away you´ll have a barrel that is only good as a paper weight.

I think a gunsmith or talented maschinist with a lathe will be able to do it.
Measure multiple times where you want to cut. Cut the barrel on the lathe, cut a crown, maschine nessasary thread or part for shroud.
Although I have never done it before, it doesn’t sound too complicated. What cutting implements and speeds should be used on the lathe I have no idea :3:
