Is my SIG 220 the only one that slugs large?

[got_lead?]

Hello all:

Quick question for the .45 ACP shooters. I have a SIG 220 that slugs at .4525, is that unusual?

Not that it's a huge problem, but my other six .45 Auto's all pretty much measure .451"

Thanks

.45 ACPs are one of the more consistent chamberings, most running at .451 to .4515. The good news is that .4525 is only about .0005 to .001 larger than normal, so you shouldn't
have too much trouble getting boolits large enough. You probably want to try a .453 diam
or .454 in that one, assuming it will chamber OK.
