I want to enlarge the diameter of a Barnes TSX from .311 to .312".Has anyone enlarged the diameter of a jacketed bullet - or in this case a copper bullet - using liquid teflon, liquid enamel, or powder coating? I am thinking of dipping a bullet's shank into liquid paint and then baking it, or heating the bullet and dipping it in powder paint before baking it.

It's difficult to imagine a rifle barrel noticing a thou difference. A good example is many .303 Brits shoot just as well with bullets .310-.312 inch.

You could use the new Rotometals lead free bullet casting alloy. It's been fixed with the addition of .75% antimony. Instructions and link to a forum thread explaining how to use it on the Rotometals product page. If you're really interested, message me.

No, but keep in mind this is the Cast Bullet Association forum, so the answer you want may not be here.

Conventional jacketed bullets are pretty forgiving about diameter with slightly undersized bullets capable of good accuracy. Perhaps a Barnes copper bullet would work similarly. I don't know anything about painted or coated bullets and this may work in your situation, but you might try the Barnes as is for comparison.

I shot with a man in California who paper-patched jacketed bullets to fit odd-sized bores. I do not know if you can paper-patch this thin for an added .001 total diameter.
The second possibility is to bump the bullet in a .313 or .314 die to allow for springback after bumping.
If the bullet is flat-base, it should bump up .001 as the bullet hits the leade before beginning rotation. This is how I've known I had an oversize bore when experimenting with a new rifle; the rifle would shoot flat-base well, but not boattail bullets.

Is there any reason that a jacketed bullet couldn't have it's diameter enlarged by .001 or .002" by powder coating just as cast bullets are?

Jeff is right my Tikka shoots .224 bullets into under one inch groups with a barrel that slugs at .225. Just shoot it and see what happens.

Thanks for your replies. I've tested the Barnes once along with Speer .311-150sp and Hornady .312sp. The Hornady test loads grouped better. I'm guessing it's the bullet diameter. I want a decent hunting bullet load for my rifle and CA only approved copper bullets. Unfortunate because I would prefer to hunt with a bullet I cast and used to assemble my hunting cartridge myself.
