Hello folks!

I will be reloading for the .45 ACP cartridge using Unique powder. Of the ones listed here at this website - http://store.midatlanticbullets.com/38caliber105grainflatpoint-100countmatchgrade-1-1-1-10.aspx , should I purchase the .451 or .452 bullet.

Thanks for your help.

Usually, you would use .451" jacketed bullets and .452" lead bullets in the .45 Auto.
But I'm sure all the "slug your barrel" guys will be along soon to tell you to do something you really don't need to do.

Well don't come whinin to me if you get leading in your barrel...

Sluggin it will tell you EXACTLY what size to order.

You always wanna order .001 - .0015 over your barrel size.

why not? that's what there made for , And maybe we should ask what gun we are talking about , I hear 45acp, and I think 1911 or Tommy Gun,

Arch is on spot on what he has posted, If you get any leading your pressures don't match your alloy.

The website lists bullet for ACP & Colt. OP order COLT bullets to use in a .45 ACP cartridge. Poor choice of bullet even for the 45 Colt. Bearing surface is short & bullet length may not produce best accuracy in a 1911 barrel twist. IMO. Standard lead diameter is .452"

It is listed under both their .45 ACP & .45 Colt bullets. It has a crimp groove for .45 Colt, which may or may not interfere with the case mouth placement if loaded for .45 ACP. It is too light IMO for .45 Colt, but usable in .45 ACP, weight wise.

If I wanted to shoot 185 Gr in .45 ACP I would probably choose a RN or SWC. I shoot both the 185 Gr HBRN and SWC from Berrys. No lead that light.

I would lean towards their 200 Gr TrFP (http://store.midatlanticbullets.com/45calautoflatpoint.aspx) or SWC (http://store.midatlanticbullets.com/45calautoswc.aspx).

The 185 Gr RFP dual design bullet may work just fine though.

Its 180 grain & to me the crimp groove = Colt Bullet. http://i338.photobucket.com/albums/n420/joe1944usa/th_CastBullets_20090207_005.jpg (http://s338.beta.photobucket.com/user/joe1944usa/media/CastBullets_20090207_005.jpg.html) No crimp grooves. :)

My Saeco 4 cavity .45 ACP mold is for 200 Gr SWC, but I like the look of the Saeco 185 Gr SWC. :)
