75gr A-Max Powder Recommendation

[WDB_AR10]

I'm about to work up a load for my 16" barrel 1-8" twist AR using 75gr Hornady A-Max, and was wondering what powder people have had the best results with for that combination or one similar to it. I've heard Varget is a good one but burns slower, I have access to H4895 and H322 and have heard some good things about both. Any advice is appreciated, this is my first time.

I would think that a 75 Amax is going to be a bit long to load at mag length in a AR

If your trying the 75 gr A-Max in an AR-15, please realize that Hornady's recommended OAL for the 75 A-Max is 2.380". Bullet set back, at mag length (Max OAL length is 2.260" for AR-15 mags), can be a major concern since the ojive of the A-Max is inside the mouth of the case.

They can be single loaded in an AR, but that's not what an AR is designed for.

If you can find it, 2000MR will push a 75gr bullet pretty fast, and it meters nicely for progressive presses.

As said, the 75gr A-Max in an AR is a single-load proposition.

That said: Varget, RL15, 8208XBR, H335, 2000MR, etc etc.

Thanks for the feedback. I'm finding more and more sources that say not to load the A-Max to mag length for multiple reasons... I may decide to go with SMK 77gr instead.

This is a much better option when you're limited by mag length. The Hornady 75gr BTHP Match works well, too.
