....may test out some 45acp with unique eventually.
It works in .45.
Just like everything else, results are all application based.
Tried it way back, heres what I found-
.45 acp is one of those odd cartridges that will work with anything. You could take an equal mix of sun-dried dog swirls from out in the yard, grind up some match heads with it ( Ohio blue tips work best) and launch a 230 gr head with enough oomph to cycle. Its one of my favoriteistist rounds to shoot in large quantities. Nothin says "wrong house" like 230 grains of hatred. I'll be buried with my .45.
Unique is one of those.....................unique........powders that have a broad application range. I think it goes from .25 acp all the way up to shotgun loads. I'm pretty sure theres some cast rifle loads out there too. Had really good luck with it in .44 spl and mag, but thats not this.
Heres what I ran into with .45 acp and unique.
It works fairly well with 230 gr heads. It works with 200's, but it was blah (for a lack of a better description)
It works with 250/ 255's but I had a bigger s.d./ f.p.s. spread and I was trying to hit a consistent p.f.
Played around with charge weights and o.a.l's and noticed it smoked a lot compared to other powders. What I pulled for parameters at the time was out of a Hornady manual, and I tried it in both jacketed 230's and cast 230's and 200's. Soot was another more noticeable by-product.
Probably not a huge deal or maybe more manageable if its slow/ slower fire type shooting.
Not ideal for rapid or speed shooting. Has a lot to do with barrel length and burn rate.
More noticable inside than outside. If you're going to try and run a 5/ 7/ 8/ 10 shot string, you'll notice you're shooting through a cloud. Not the best for an indoor plate or bowling pin match.
I'm not trying to talk you out of it, just passing along a heads up of what I've run into with it.
I hope your results are better than mine.
