Reloaders O.A.L.

For experienced reloaders out there (Ponch, Lonely Raven, and some other good looking reloaders out there). What is an acceptable overall length for a .45acp? I use lead swc 200gr. I've been following other people's advice on O.A.L. at 1.250. My question is what is an acceptable O.A.L. to you being over or under the 1.250? 1.246, 1.247, 1.252 or does it really matter? I'm using these on 1911s. Colt Gold Cup, Ed Brown Kobra and Kimber for a run and gun competition. I just wawnt to know if I really need to stick to 1.250 O.A.L. T I A.

Acceptable is anything OVER and allows for reliable feeding and fitting into the magazine. Anything UNDER and you increase pressure beyound teh safe limits of the cartridge case and that could cause a blow out.

You realy gotta go way lower to make a diffrence but to much and you wil have problems. Safe on the low end would be as low as 1.245

I'll look up some of my data later. I'm headed out to do some leaf blowing right now.

Think of it like compresion in an engine. Low compresion engines are genraly less violent and produce less horse power than a high compression engine. Get to much compression or to much boost and what happens!!!

Oh ya... there are some cartridges that need to be loaded low or have a heavy charge of powder to make safe but the .45 isnt one of them.

People who load for .357 mag and want light loads have to watch out. It's not important in your case buy very related.

This... don't go crazy over. but some over and feeds good, you are set. I would reccomend not going under at all. no reason to really.

Thank you very much guys. I forgot to mention that I'm using Bullseye powder at 4.7gr. I will be switching to Titegroup powder when the Bullseye run out. The ones I have that are over the 1.250 o.a.l. were mostly 1.252 and some were up to 1.255. The ones that are under the o.a.l. mark were mostly 1.246. I put aside anything under 1.246 (1.240 - 1.245) for plinking/range ammo but what Ponch said makes sense. I put them aside for now.
