Remington 6 mm made in 70's has a ring around the inside the barrell about 1.5 inches from end.Could you cut barrell off without hurting accuracy? Thanks.

Yep, but you'd have to recrown(Brownell's sells the tools) and be sure the resulting OAL of the rifle stays legal(most likely be ok). Don't use a hack saw. It's best done in a lathe.

Unless you have the right tools, best let a gunsmith do it.

Midway's owner has a clip where he uses a guide to make an even cut with a hack saw and a recrowning tool to finish it off. Looked pretty easy, I don't know if it is that easy cause I've never done it. I suppose cutting it this way may not give as precise a crown and could effect accuracy if you are looking for sub moa gun, then again I think it could work just fine. Here's the link, he tells you the tools you'll need of course.

I've done it with a hack-saw and re-crowned. It takes a good eye, a steady hand, and some skill with a file, but it can be done.

You don't suppose all those Kentucky rifle makers 200 years ago used lathes do you?

Lathes have been around almost as long as water wheels to turn 'em.

Larry doesn't exactly tell you everything..... The method he shows will work but it's not the best.
If you don't require a front sight skip the dovetail jig and save money. What you can't skip would be a facing cutter (squares the end of the barrel to the bore) the crown cutter (obvious) and the associated bore guides.
If you buy everything needed (for a single caliber) you'll be about 90 to 115.00 deep in tools. If you're only doing one barrel it will probably be cheaper to have a smith do it for you. If you might do other barrels later then you may come out okay on equipment. Other calibers will require additional bore guides but the cutters will cross over okay.

Thanks for the replys.

Remember that the last thing the bullet touches on the way out of barrel is the crown and rifling there. If the crown is crooked or rifleing is dinged then accuracy is shot.
Let a good gunsmith do it, that way is cheaper, faster, if he is good you'll won't be able to tel without measuring.

Or split the difference. Cut the barrel and square it as best you can using a hacksaw(24 tpi blade) files and a machinist's square. Then take it to a gunsmith to have it recrowned. You can recrown it yourself with a round headed brass screw and grinding compound in a variable speed drill. I use a round white grinding stone kept wet with honing oil. Finish with a good cold blue. It ain't that hard to do. (ETA; this is for hunting rifle accuracy,if you are shooting for groups go the gunsmith route.)

Do you have to cut it back? If the bulge isn't hurting accuracy I'd leave it alone. Just be sure to let everyone you see know that it was already there when you got the gun. ;)

If you've noticed an accuracy problem I suggest trimming it back and letting a gunsmith face and crown the muzzle.
