I have a Marlin XT-22, I love the gun but I don't like the 22" barrel. I would like to shorten it to around 18". My question is what is the best way to do this? I saw a recent thread where a hacksaw was used. I do have access to a lathe and someone who can run it better than I. Also is 18" a good length for a .22 barrel? Thanks in advance.
 
Re: Barrel shortening question.

Think of it this way. The US Army fires 224 dia, 62gr bullet over 3000 ft per second through a 14.5 inch barrel with a 1:7 twist, at targets to and beyond 300 meters. But it does depend on your twist rate. Imho, I think you will be ok with 18". If your not sure check the provided link from shilen barrels look at 224 dia. Hope this helps

Good luck

good... make sure you dont have a burr at the end of the rifleing when done...

18 is fine, under 800y.... you will lose about 200fps off your 22" going to 18"

Um no, He's talking about a 22 long rifle. Standard velocity ammo burns all of it's powder with in 14"-15". You will see no velocity loss going to 18" from 22".

Perhaps you were thinking centerfire?

... thought 223... it still will lose some, but not anything that will hurt a 22lr...
 
Re: Barrel shortening question.

Yes lol it is a 22 long rifle, I have emailed my friend with the lathe and hope we can get it finished quickly! I guess the big deal is to make sure there are no burrs in the rifling and a clean crown? Correct? Thanks guys!
 
Re: Barrel shortening question.

Hacksaw will work, but you'd need to make sure the cut is squared off when you're done. Then you need to put on a crown (a little harder to do by hand). Matter of fact, I read about students at a precision long range class using a sawzall and a hand crowning tool to shorten their barrels.
 
Re: Barrel shortening question.

think lathe is the best way to do it. hacksaw and lapping compound i suppose would work but that seems so...crude.

take the barrel to 16 inches. anything without 'hyper' in the name has burned all the powder anyways.
