Different Brands of brass and accuracy?

[ArkansasFatboy]

Guys I am new to this and was wondering if there was any brass that was better than others and if you have mixed headstamps should you only load lots of one kind of brass. For my .45acp I have not worried about headstamps because what I am reloading is just for plinking. But I have read that for accuracy that different cases will perform differently.I recently bought some once fired .44mag brass from my local range and after sorting I have 5 differnt headstamps (winchester, pmc, starline, remington, federal, cbc, and had one oddball case marked nny) which of these is the best or is there a best most of what I have are winchester and then starline.
Any info is greatly appreciated

All brass will work fine in all your firearms except A-merc. Pure junk!!!

With precision rifle loads it DOES matter what brand of case to keep the loads consistant. We are talking sub .5MOA type shooting.

With pistol loads, if you can notice any difference in accuracy with mixed cases you are a whale of a better shot than me.

I know it is contrary to a lot of opinions, but I took a bunch of mixed brass in 9mm and loaded it all with the same recipe. When I chronoed a mixed bag of many different types of brass vs. when I sorted them out into like kinds I saw significant differences in SD's and velocities. On the targets it was obvious out of my 210-5 that the brass mattered.

My experience is that with accurate guns, mixed brass is a bad idea and I now sort them out at either load time, or during the box up phase.

My suggestion is easy. Do the same experiment and see if it matters in YOUR gun. It did in MY guns, but as you can see it may not in all cases.

Good luck.

Going from rifle loads to pistol loads I treated them the same early on. I sorted my 9mm by brand and even trimmed it. Couldn't tell any difference so now everything just gets mixed up and no more trimming.

I keep brass sorted for rifles. I know that makes a difference.

For pistols I have shot mixed 45ACP brass for a long time.
But, now I have reason to some madness. I sort the WW and Fed for use in the 625, and all other head stamps except AMERC, gets sorted for use out of USP's. I then load in lots of WW / Fed for production runs.

For 9mm well that is bit of different deal, I sort that out so far. It goes through a pair of glocks.

Now, shooting Sig 210 well I bet anything that can be done to max out accuracy is okay by me!

I used to like 357 mag Starline brass, as it was good and hearty same for 44 mag.

Yes, What Peter M. Eick said.

And what RecoilBob said.

If you and your firearm are up to the task, then yes, pure accracy can only be attained by having all components the same in a reloaded batch.

That said, there is a twist. I don't mix headstamps in a loaded lot unless they're just intended to be plinkers.

I have found that Win, and PMC are the most accurate through my Kimber and Colt 1911's. Same with my Ruger .44mags. -And any .357mags I've owned. (I think the DW15-2VH is accurate enough to tell). My rifles see a steady diet of Remington, Win and uh um... Federal brass. The magnum gets the Rem and Win with the Win being the most recorded in my book for the smallest groups fired.
