Barrell Shortening

[hughesey1552 0]

Hi , I am thinking or shortening my barrell on my s200. With the silencer on now the barell is 24" long to the start of the breech and I Think i could take off around 2.5" maybe 3" but I would have to take the silencer off so be sure. While shortening i can also thread the end so it can take a better silencer without an adapter.

 

What i want to know is wil this affect the accuracy or the gun?

 

Also does is the barrell of a gun concentric to the O/D?

 

Cheers, Hughesey

Come on someone must know something about it. If i can find out a bit more info im gunna try and do it at work tomorrow.

if you are talking about taking the cut at the muzzle end then yes it can affect the accuracy as you will cut the choke off the barrel end.if you are going to cut it do it at the breech,but cutting it either way will reduce the power of the gun.

If its the crown you mean by choke, I will be able to recrown it at work. I didnt know that it would reduce the power of the gun though. How much will it reduce it by??

the crown is different from the choke mate.the choke is where the inner bore of the barrel reduces slightly near the muzzle end.

power loss varies but i would guess if you cut 3 inches off then maybe you'll lose around 1ftlb.thats ok if you know how to tweak the power back up to allow for the drop,while still keeping it under the legal limit.

if you do this you'll also get less shots per charge,needing more air per shot.

Hmmm I hadnt read anything about the choke, when id been looking on the internet. How would a gunsmith do this as they cany possibly make the recut barrell smaller at the end could they.

the answer is obvious buddy,cut it at the other (breech) end.

it'll then need to be re machined to fit.

ahhh i see lol. Is the barell threaded at the breech end so fit into the action then? If so it wouldnt take to long to do. Does the bore and o/d of the barrell run true to each other (concentric)?

sos.... big-word boy.. it narrows towards the end its not concentric,if you want a shorter barrel buy one.or a different gun.... barrel tech is an exact science. Don't f**k with the barrel man? Download deer hunter game if yr bored..How's yr knee lad?

The knee is fine, im walking and hopping about agin, been back at work for a week now, and glad to be there. It cant be that hard to do though really can it? If a gun smith can do it on a lathe im pretty sure i will be able to aswell (not being big headed). Hows finding permssion going? Im going to pop down to farnworth golf club on saturday I think and ask about shooting on there (if they have a rabbit problem of course).

Well on with letters sent six will send six more when i get stamps got 2 replies will get in touch with me when they have some rabbits....mmmm?and about yr barrel there is a optimum lenght for accuracy you would be gutted if you knackerd yr barrel ,an expensive experiment.

[hughesey1552 0]

I was kinda hoping that someone on here would know that kind of info as i know there are some fountains of wisdom on here lol. Hmmm sounds like they arent that interested? I was mooching around in atherton with ma mate the otherday and saw a few big rabbits in a field so im going to ask the farmer at weekend so hopefully that will go well. My tutor told me that there a sht load of squirells liing in the mini woods behind the wokshops at college, its a pity they always seem to pick a safe place to live :realmad:
