If I turn a 22 RF barrel holding the barrel with a collet and the chamber in a live center, will it wreck the edge of the chamber? The object is to modify a barrel to fit a 513T, which is pinned as opposed to threaded. I haven't turned a barrel before, would rather I didn't cause problems. TomP Our country, right or wrong.

Make a piece of brass to cover the center. | |||

What he said; don't put the center directly onto either the chamber or muzzle unless you want to clean them up later. | |||

Thanks, I will make one with angles to fit the center. The barrel tenon is 1". Would there be any benefit over a brass center, to make a round cup that fit snug over the end of the tenon, with a center cut? TomP Our country, right or wrong.

Just more work for no benefit. I use sheet brass and make the center punch through it. Or you can get fancy and machine a bore fitting plug (or in your case, a chamber fitting plug) with a center recess in it. | |||

I had started a bore-fitting plug, but it sounds like the path of wisdom is the brass sheet. Thank you. TomP Our country, right or wrong. When right, to be kept right, when wrong to be put right. Carl Schurz (1829 - 1906) | |||

Collet? is this a straight taper barrel years ago I started cutting a center in the primer pocket of the appropriate case. Works great so long is chamber is not sloppy. Never tried it on a rimfire. Wally Waggoner Rifles | |||

It isn't straight, it's a 40X rimfire barrel. I think the collet grips it enough to turn the rest of it straight if the cuts are light. I had thought about putting a fired case in the chamber to cushion the edge of the chamber but am concerned that it might get stuck. TomP Our country, right or wrong.

Make a brass pin that fits the chamber tight and center drill it for your center. I do this to true outside of barrel ends before setting them up to chamber them. | |||
