I'm not the best shot in the world but I try and I am learning.

 

I bought a box of blazer aluminum cased ammo. I couldn't group my shots at all. Switched to brass cased remington UMC and I was able to group really easily.

 

But there could have been a ton of other variables, so I'm asking you guys -

 

If you've shot aluminum ammo before, have you had trouble with accuracy? I know with pocket pistols it's a bit of a challenge but I'm wondering if the ammo also plays a part.

 

This is with my springfield XDS 45 ACP, target was 15 yards outdoors. If I could find some ammo I'd like to try it with a 9mm.

I don't have many problems grouping blazers out of my SA MC Loaded 1911, but a lot of ranges give you crap because they can't just sweep them into their bins so it's deserved.

No issues with aluminum Blazers in any department although extraction is sometimes sticky with revolvers.

I run aluminum 45s in my 1911 for competition. No problems with whatsoever. Ran aluminum 9s in my 92. Again, no problems. Only comment is feeding is a little harder as the aluminum casings are not a slick as brass. They drag against each other and the magazine feed lips more. Haven't had a FTF as I use standard weight recoil springs so not a problem for me.

Most of the aluminum cased ammo we chrono'ed has run on the lighter side, so it may make a small difference, however in most cases, it is not likely to be the ammo for the most part. Lots of other variables.

Don't think that is it. I shot some Blazer Aluminum .40 cal just an hour ago and put down some of the best groupings I have ever done.

I used some Herters aluminum this past weekend.

 

I was having accuracy issues, but I don't think it was from the aluminum, per se, but rather from the polymer coating on the bullets fouling my barrel. Once I scrubbed the barrel, I was OK again, but I wont be using this ammo for competition again.

I thought it was me as the CCIs do feel lighter. I ran a 18.5lb spring on my 1911 and my casing were just lobbing to the side. I've sinced dropped back down to my 16lb'er.

 

Didn't know Herters made aluminum too. Every time I see Herter, I think of steel and just pass on them. Only time I've messed with that brand was with steel 7.62s. Got the occasional slow burns.

Thanks for the replies... I may try another box sometime and see.

It's Cherry Ridge. You have to police your brass anyway. I think I could even get away shooting steel cased ammo there.

Aluminum cases are just dirtier i have learned from my own experiance. Accuracy i havent had an issue
