RIA 10mm won't shoot Blazer 200 grain..

I recently came into around 600 rounds of Blazer 200 grain 10mm aluminum cases ammo. My RIA 1911 will not reliably shoot them. It may shoot one or two rounds then it fails to either extract or eject.

It shoots all other 10mm just fine..

Is there an inexpensive fix to this, may be a new guide rod spring or something?

I don't even know what rating the spring on it now has, how would I know what spring to order, if this is the fix?

I shoot a lot of 10mm and have found that blazer to be really dirty ammo. The aluminum cases also seem to swell a little in the chamber. You may have already done this but clean the gun and chamber really well. Shoot some blazer and check it again for fowling. I'll bet that is part of the problem.

it's better to pay the $2 more per box of brass-case ammo, and save your brass, and reload it....

The Lee hand presses are not expensive....; reloading is therapy, saves money, and, a good time filler!

I wouldn't want to load pistol ammo in any significant quantity on a single-stage press, but 10mm is a prime candidate for reloading due to cost and variety of 10mm loads.

I thought everybody knew you only shot alum case ammo in the backyard in any weapon? It always expands and is hard to extract. You will never get consistent performance in any high pressure caliber with that stuff. You oughta try it in a 44mag! you'll end up tapping the shells out some if not most of the time.

You can't cheap out with a 10mm, that's like putting walmart gas in a ferrari.

My experience with aluminum case ammo is it will display feed issues if magazine lips have not been deburred and smoothed. And this one the top round of a full mag. I've shot 44 Mag, 357, 9mm and 45 aluminum case stuff and find it shoots fine, extracts well and has caused no malfunctions for me except as stated in the first sentence of this post. I shoot matches with it (9mm in 1911) and it hasn't malfunctioned.

Sounds like the OP's issue is more a power factor or extractor problem than an aluminum case issue. It feeds, it shoots...extraction and ejection are the issue. Mic the case rim diameter of the brass vs. aluminum cases. Inspect the extractor for tune (especially the bottom hook wall), defelction and tension. Try a lower power recoil spring (last on my list).

You might want to look up the ballistic data for that ammo. About half of "10mm Auto" is loaded identical to .40S&W.

If your gun is set up for true 10mm, it might short-stroke with the wimpy stuff.

Recently bought a couple 10mm 1911 and was searching for some break-in ammo until I can set up to reload.

It took some footwork to locate legitimate 10mm velocity target loads locally. Also was shocked to find that quite a bit of the hollow point ammo was showing some weak velocities as well.

It's like someone buying a new Dodge Challenger Hellcat but only driving around with the restricted valet key.





Ammo08, I wish I had some solutions....I had some issues with aluminum cased 9mm Blazer (never tried in 10mm)....stove piping in a CZ75. While problematic, I was able to shoot the small amount I had. Gave me some good practice with error recovery, lol. I never made any adjustments or changes to my gun....just worked through the ammo.

600 rounds is a nice chunk of ammo.....hoping you can get it to run.

I can't speak about 10mm Blazer but I bought 2 boxes of 50 a couple years back for my new 357 magnum revolver. Chrono'd 40 rounds. That stuff wasn't any hotter than a premium 38 Special +P..
And my stainless revolver was black by the time I finished the box. I still have the 2nd box, all unfired.

Don't really think aluminum case would really fit a 10mm load application very well. I did not even like aluminum 40S&W, let alone consider it for 10mm.
To be fair CCI's Blazer AL has shot fine & fed/extracted adequately in several of my 9mm, 38spcl, 44spcl & 45auto pistols/revolvers. Saved a few $ when I was unprepared with my own loads and was leaving cases on the ground.
Just don't see it as a good choice for a high PSI load like real 10mm.
