small primer .45 acp

Just curious, as I've been away from the forums for quite a few years, but what is the reasoning behind using small primers in .45 acp cases?

I know the bench rest crowd found some potential differences in using a Russian case w/small primers, or, if not the actual case, the premise that there was an advantage. 

Again, just curious.

I'm sure some junior cost analyst figured out they could save .001 cents per round. A curse to mankind

A pox on the engineer who came up with the idea.  He should be flogged on a weekly basis, and then made to disassemble a Star reloader, set up for .45, with a small-primered .45 case jammed in it on an hourly basis.

Oddly enough, I prefer the Fed case with SPP. I have a 5 gallon bucket of OF Fed brass. Most folks prefer the LPP stuff. I recently traded a bunch of brass at the rate of one LPP case for three SPP.

I only load match SWC ammo in a heavily massaged older Gold Cup. Fed brass loads without drama, and the gun does not care about primer size.

That's a little lenient, IMO.

The primer pocket swage on my 1050 has saved me several squished primers and possibly a magazine explosion.
I'm much more careful now, still don't sort but I look at the cases I pick up at the range.

lead free primers are currently only produced in small size.

I think some local environmental regs caused some LE departments to request them.  They probably all converted to 9MM due to the increased cost.

I have about 1500 SPP 45ACP cases saved up in case there was another primer shortage. I don't think I'll run out of LPP this time but I'm ready if I do.

I tried clicking "like" twice. Does not have the desired effect, just cancels the original "like" vote. Grrr.

But, to rather badly para-phase the lyric; Tommy, the DD&B shooter, sure plays a mean bullseye!

I'd love to get a bunch of small primer .45.  .45acp is the only large pistol primer caliber I intend to load.  Everything else (9x19, .38 super, .38 special, etc) is small pistol primer.  I'd love to be able to convert to all small pistol so I wouldn't have to switch my primer tubes back and forth on my Dillon 550.

In a low-pressure cartridge such as the .45 ACP?  Probably the reasons stated above.
 
In a high-pressure rifle cartridge such as the .308 used of PALMA, the rounds can be loaded to a little higher pressure without the primer pockets stretching out.
