Default Small Primer Cased .45 ACP

I was setting up my brand new Dillon RL-550B this week-end and started working through my backlog of .45 ACP empty cases. My empty brass is a mix of my own prior re-loads (mixed manufacturers) and range pick-ups.

I found about a half dozen .45 ACP cases with small sized primers. They were marked "WIN NT". I culled and discarded the rest of them.

I had heard of small primer .45 ACP, but had never see them before. What is the intended purpose/benefit of this case variation?

I ran into a bunch of these. That is a winchester Non-Toxic load (WIN NT).

They are a small pistol primer pocket. You can reload them me I just toss them over my shoulder into the trash pile. It is not worth the hassle of separating them and changing the priming system out on your shiny new dillon.

You will need to cull them and trash them or keep them separate from the others and load them when you change out your dillon priming system.

The Speer non-toxic frangible 45 also has the small primers. I get these by the thousand so I hang on to them. With the current primer situation, I find it easier to get small pistol primers than large. The small primed brass enables me to keep shooting when primer supplies get low.

It seems to me the only Non-toxic ammo made for handguns is in 9mm, 40 and 45. They can make one kind/ size of primer and use it in all three. The Speer non-toxic .223 brass is very easy to reload. Easy to re-size. Pressures may be lower than standard ammo. I believe they make non-toxic .308 also. It would be interesting to see if they use small primers for those.
In life, strive to take the high road....It offers a better field of fire.
