45 ACP Primers
The Old Salt
Member Posts: 94 ✭✭
I have been re-loading for years, but tonight I ran across a first when I started re-loading 45 ACP for the first time. Different Mfg of cases use different primer sizes. I have Winchester cases that use Large Pistol Primers. Then I have Federal & Fiocchi cases with small primer pockets.
The question now becomes, what primer to use? Small Pistol? Small Rifle? Small Magmum Rifle? I understand that using the rifle and Mag rifle primers would provide a hotter ingfition, but would they require a heavier hammer fall that the Ruger SR 1911 provides? Someone out there has run across this before and worked out the answer, so please porvide. I am planning to load 230 gr cast RNs on top of 6.0 gr Unique. I am looking to achieve a IV in the range of 850 fps. Also, C.O.L.? Thought I read that someone was loading their cast RN a little longer for the Ruger to eliminate feed issues, but don't remember what he recommended for C.O.L.
Took the Ruger to the ragne last Sat. I hadn't fired a 1911 since my Navy days 40 yrs ago. Fist 5 grouped at 7 yrds was 1 1/2" with 4 in the 10 & 1 in the 9 ring. This old half blind bi-focaled guy was very happy that I could hold all the blurry sights in line that good.

It will cost you 25-40 fps which is not much.

I ran into the same thing with the primers, so I went with all small primer brass (bought on the auction side) because I already had small pistol primers for my 357. You can also use small pistol magnum primers and get your fps back up. I even traded some brass with another forum member,latge primer for small primer. Sure beat tossing them out. Happy shooting.
Has anyone tried the small rifle mag primers? Measured them with a caliper and they would fit in a small pistol primer well, but would you have sufficient hammer fall to ignite them? Would you have to adjust your loads because they were hotter?
I do not see the advantage to a small rifle magnum primer. Federal used to recommend their small rifle standard primer for .357 magnum before they came out with magnum pistol primers.
most i have seen are federal. and blazer brass loads which i believe is federal. oh as a side note toolfogie the brass did arrive. if i find more sp i'll send it your way.

It's also ballistically a bad idea. There's no free lunch in reloading. A primer that's too hot doesn't give you only more velocity. It will also give you premature bullet movement, altered powder burn and increased pressure, none of which will help accuracy or gun function. It has long been known that the mildest primer often gives the best accuracy, and the smaller the case volume the more true that becomes.
