45ACP Blazer Brass Small Primer Pockets-What Primer to Use?

[gerrym526]

Did my usual range scrounging for brass and came home with a load of 45ACP. In sorting through the cases, there were quite a few Blazer cases with small primer pockets.
I'm accustomed to loading 45ACP with Large Pistol Primers (use CCI 300), but can't find data in my reloading manuals that specifies what small primer to use.
I have CCI 500 for 9mm-would that be the right primer? Or something else?

Or, should I just throw away the Blazer cases and get on with reloading my normal way? If I have to buy a primer I don't currently have in my reloading materials inventory it doesn't seem worth the additional cost.

Thanks for the help.
Gerry

Any small pistol primer is acceptable. Don't overthink this.

The factory loaded these with standard CCI small pistol primers.

Any small pistol primer. Don't throw them away... some loonies actually prefer them and will trade you LPP brass for them.

Yep.

I prefer to have both. This way if primers get hard to find I can use whichever I find (if I ever run out)

You already have SPP that will work very well, your CCI-500 primers. I also use them with no problems. I can't shoot the difference between accuracy of the SPP and LPP brass, I see no difference at all.

I save the SP brass and use them when the likelihood of recovery is low.

I have tried both and prefer to keep it simple and only work with large pistol primers where traditional. However, if you use a max load for a small primer back it off a bit before you use the same load with a large primer. The large primers always seem a bit hotter. Obvious I know, but it pays to always start low and work up any load with any change in any component.

I keep them all and will reload them all. I have used CCI, Winchester and S&B in them with both large and small primer models and can't tell any difference.

If you don't want the small primer cases send them to me. I'll pay your shipping costs.

I belong to the incredible Sacramento Gun Club. The RSOs sweep the brass into separate piles for those of us that reload! Other wise I would help you out!

I wonder is the SPP will exhibit lower ES in velocity from more consistent ignition, like with many rifles.

There's an interesting story behind the development of the .45 ACP using the small pistol primer, mainly it seems centered around efforts to reduce lead exposure from using the LPP that the cartridge was originally developed with. Prior to googling this all up for a read I knew there had to be a reason, either economic or other, for manufacturers to go this route, and sure enough there is.

The spp brass saves me at least seven minutes by not needing to change my primer feed when going from 9mm to 45acp.

Stash the small primer brass for a rainy day.

I use CCI 400s on SPP 45 brass. Never had an issue. But any small pistol primer will work fine.

+1 on what @cheygriz said.
A CCI 500 works just fine and I've not seen any statistically significant variations on chrono data. While it's a PIA to sort large and small primer cases, for my progressive press it's easier to just run one or the other depending on what primer setup I currently have. I've not yet graduated to the separate presses for large and small primers.
I am also starting to venture in to the .45 revolver arena and reducing the DA trigger pull. I've heard that the small primers can be an advantage in that you can get reliable ignition at a lower poundage, but I've not proven that to myself, yet.

A while back I did my own comparison. Bought 100 small primed 45 ACP brass of two different head stamps, and used 100 of my large primed cases same two headstamps. Long story short, not enough difference to bother. I do keep the SP separate from the LP both empties and loaded (identical loads just different primers)...

 

[Walkalong]

I have so many LP .45 ACP cases I leave the SP ones at the range for someone else.

 

[illinoisburt]

Any small primer works. Since I don't usually load any other SPP rounds, just use standard winchester small rifle primers instead. Same physical size, no noticable difference shooting since I don't run max loads and have standard hammer springs on my pistols.

I'm one of those loonies. That's because people give me SPP brass for free whereas I would have to buy LPP brass. Plus, every other pistol cartridge that I load uses SPP, so it just makes life easier to stay with only having to buy SPP.

I use regular (not magnum) primers in my SPP 45 ACP and have not had any problems.

 

[Erief0g]

I load both. Negligible difference.

If coming off 9mm tool head go with spp. If coming off 44 mag tool head load the lpp. You get the idea.

I'll be making some chrono strings on them in the next few months but time seems limited due to heavy 9mm trigger time

Use the data listed in reloading manuals for large pistol primer 45 acp to load the small pistol primer 45 acp
cases . Pressure will be ever so slightly less ...ergo , no problem .

Always something new to look out for .
