I have seen adds for large and small pistol primers, is there any different between the two except the primer size?
I have also see supplies listed as 45 auto. I assume this is the same as the 45 acp. just dropped the colt pistol from the name. Am I correct? |

Large and Small are personal preference. Someone had done testing, and found no significant difference in loadings of the different primer sizes.
Many prefer Large Primer, simple because thats that .45 is "suppose" to be. I use both, without problem. 45 Auto and ACP are the same thing. |

The thing with the small pistol-primer 45 brass is: a lot of that stuff has crimped-in primers. Meaning you gotta cut or ream that crimp out before you can reload it. There might be crimped-in large primer too - but I've never run a cross it. What brand of .45 SP brass are you loading with primer crimp? I just loaded 500 rounds of Federal 45 brass with SP, and I didn't find a single piece with crimp. Maybe Blazer? Some of the other brands? |

I use Berrys. Tens of thousands of them. In fact, I just loaded a thousand. I like Winchester 231. It meters perfectly and accurately with the tiny grains. I also use large primers mainly due to the 5 gallon bucket of free range brass that I accumulated before small primer .45 existed.
I was fine with the Dillon Crimp die until I got a Sig GSR. I had to go to a Lee FCD for just that pistol. Gun is long gone, but still use the crimp die with no issues. Recent data on Berry's website says you do not have to reduce loads and FMJ loads are fine. Verify this for yourself, but I remember reading that. FWIW, I have always used the FMJ loads with berrys.  
45 (.452) 230gr RN - 500ct
gun ammunition This is our #1 selling .45 caliber bullet. Our bullets are 100% copper plated and restruck in a carbide final size die for a uniform bullet. Our .45 caliber bullets are .452” diameter and with the benefit of the softer copper plating they should prove to provide you with improved accuracy. Our bullets can be loaded with any published load data for any 230gr bullet, any of the loading manuals or the powder manufacturers website should have that data for you. We recommend a COL of 1.250" These bullets are guaranteed to handle velocities up to 1250 feet per second. http://www.berrysmfg.com/product-i14521-c17-g8-b0-p0-45_452_230gr_RN___500ct.aspx |

The real issue with the small vs. large primer cases is that it makes it necessary to sort them and process them separately . Invariably some of the other type gets mixed in and jambs things up . It isn't a huge issue but a certified pain in the ass.
I have been bending over and picking up brass for years . I have given quite a bit away over the years but still have plenty and it isn't like it hardly ever wears out . I choose to just not mess with small primer 45acp brass . Not sure how much of the new brass comes through with the small primers |

Not sure how much of the new brass comes through with the small primers It might just be the environmentally friendly bullet loads, at least that is what it started out to be. Some rounds also have huge primer holes, but that doesn't mean someone didn't open them up for rubber bullets or some specialty load................ |

I believe you are correct, that the small primer movement started with the whole 'clean' primers. I think, however, that I read an article stating Federal saved like .0001 cents (or some ridiculously small number) by going to small pistol. Of course over millions of rounds it adds up. But who knows if it's true. |

I know for sure I do not have any bullseye.
The problem is my state has a ridiculous low amount of pwder you can have in storage. I am at that limit now and won't be able to get any new powder until I use a lot of what I have on hand. I don't want to have any more powder then I can legealy have

I ran a test using CCI primers, Xtreme 230gr HP bullets, and I think Silhouette powder.
Same powder charge, 50 rounds each of SPP, LPP, and SPP Magnum primers. The SPP Magnum came in about 50fps faster than the LPP, the LPP about 50fps faster than the SPP. I believe the performance difference between primer size in 45ACP will depend very much on the powder and bullet weight being used. Some powders will show no difference, others will have measureable difference. Would be good to run this same test again, but with several different powders. Might try to do it some time this summer, will be sure to report results. |

The case determines the primer size needed, not personal preference. There are .45 ACP cases that use small primers in the market. Most of us cull those out to keep them out of the processing line and mixing with conventional large primer cases. While we're discussing this, I'll note that large pistol primers and large rifle primers have different dimension and rifle primers cannot be used in pistol cases. |

I will be loading for 1911a1 from Springfield armory. I am thinking about using 230 gr rn and hp from berries bullets What powderd work for this? I know I have red dot and blue dot on hand and maybe a few others. I use Bullseye for everything, but that's me. I was sent a good number of small primered brass by a member here, and I did load testing with a couple of weights and types of bullets using small and large, and large magnum. The small primers I have are magnum, and I had some old ammo loaded with standard CCI LP, and I have switched to Winchester magnum LP. I tested 200gr LSWC with all three, and a 230gr Xtreme double plated hollow point. I do not remember exact velocities, but, both small and large magnums were within 10fps of each other , and the non magnum was about 40-70fps slower with the same charge than either. I actually loaded all of it with 5.0gr of Bullseye, which is the top end for that lead load, sort of hot, and normal upper end for the Xtreme, and I wouldn't go higher than 5.4gr on it, 5.2 was my go to, but I backed it down so I could load several types and still get good performance. The only problem I have with the small primer stuff, is I no longer load for anything else that is SP pistol, so having a lot of that brass is just a waste. Now, if I or my son get another 9mm or something, or my best bud shoots all the ammo I loaded for the M&P my son sold him, or he gets back into shooting a lot again, I have the dies and some primers, and with my LP brass being so old, it wouldn't hurt to switch over to SP for all of it. |
