Federal 45acp brass question

[trails4u]

The Winchester Non-lead stuff (Win NT headstamp) is also SPP.....just FYI. Other than that, most I have seen around here is Federal or Blazer.

I have always wondered why the .45 ACP was ever loaded with large primers in the first place? It's not like they contain a large amount of slow-burning powder.

Yeah, I have Federal 45 ACP in both large and small pistol primer. I do keep them separate, but consider it an advantage to use whichever primer I have the most. I've also got some Speer 45 ACP with the SPP. No noticeable difference when loading/shooting.

I think JMB originally designed it as spp but the lpp was more forgiving of non centered firing pins on the 1911.

This is the first LPP vs SPP thread I have seen where most of the posters didn't almost go into apoplectic fits because of SPP. I stocked up on OF SPP brass some time back. Now I have no use for the LPP priming parts for the Dillon 550B

Well, with all the concern over availability of components for reloading, when some more 45 ACP range brass became available from the LGS, I bought it. Still no spp brass, the entire bag had everything but Federal brass, maybe it's a regional thing? Anyway, I've now got about 600 pieces, and that will hold me for a while. I'm not changing primers from lpp to spp for 45acp.

Correct had something to do with military requirements and the ability to strip the guns down and rebuild with mixed parts.

I guess if I encounter more and more SPP brass down the road, I'll have a decision to make.

I believe that all manufacturers are slowly but steadily transitioning .45 ACP to small pistol primers. One day all new brass will be SPP. The only problem with it is the inconvenience of having two sizes to deal with right now, especially if you have a large supply of large primered brass already on hand. If you are starting into the world of loading .45 ACP today, it makes no sense to involve yourself with large primered cases. Ditch them and focus on the small primered stuff.

When John Browning designed the .45ACP, he developed the ammo too.
He used chopped off .30-06 brass for the cases and they had large primers.
It worked well, and .45ACP ammo as we know it went into production.

Up until now, large primers for .45ACP has been one of those things that, "We've always made them like that".

That is what I do with my 30-06 brass. Never had a gun chambered in it.

[T-Bird]

You cut off 30/06 to shoot in 45ACP? wow! sounds like a lot of work to me.

Because it is based on the 30/06 case.

T-Bird,

The reason for the existence of the SPP .45 is the lead-free priming (CleanRange, Winclean, etc...) that has been largely marketed for police training facilities.

The major demand was for .38 Special, 9mm, .40 S&W, and .45ACP. The first three of those nominally use SPP. It was simply a logistics of manufacturing decision so they'd only need to make the lead free primers in one size.

Since you're just getting into the .45ACP, it's decision making time. I have about 40 years of history - and brass - built up with the round. Because of this, I'm well-committed to the platform in LPP, and I regard SPP as the work of Satan because I now have to look out for something I never did before. You don't have that baggage.

[T-Bird]

I'm staying with Lpp for 45 acp. For me 600 pieces is enough for a while. I never shoot one gun for too long exclusively, the others get jealous. Many of them use Lpp, but I do have 4 (2 rifle,2 pistol) .357's so I'll always have Spp too.

[Walks]

I think what bothered Me the most is that they just showed up. No one knew why ?
Now I just collect them and save them for indoor range use. Load 'em, shoot 'em and leave 'em.
