Last week I bought some .45 ammo and accidentally picked up a box of Remington 185 grain MC Flat Nose. I have several .45 semi-autos and I'm certain it will shoot in one of them. I have two pistols that have never been fired. a Les Baer 5" and a Kimber Ultra Carry 3".
Would it be detrimental to break-in either of these pistols with this flat nose stuff.
Opinions appreciated. I was thinking of breaking in both of my pistols with 230 grain ball.
