What ammo for in MP5-type guns? JHP's?

I didn't buy my MKE cause it's a practical HD weapon. I bought it cause its cool and wanted one ever since I saw Die Hard.

That's what made me buy my first MP5.

Recently ran some Fiocchi 147 gr fmj (the new style with little flat meplat) and PPU 158 gr fmj from the AP5P.

No problems. About 1000 fps for the 147, 950 fps from the 158 gr. The 147 gr had less recoil.

Also tried the Hornady Critical Duty 135 gr standard pressure. Velocity was around 1100 fps but several malfunctions with it.

All MKE mags. Accuracy excellent with all. (Holosun 503)

I'm going to run more Golden Sabers and XTP's through it. I only ran 20-30 of each before and it worked fine but I need to run more before I'd trust the gun for an HD / travel role.

Edited to ad: Tried more 124 gr XTP's. Nope. FT feed in the middle of the magazine. My AP5P won't feed JHP, at least with MKE mags.

Just wanted to update.

My AP5P, after more breaking in, is feeding JHP's just fine with HK mags. I believe the mags were the difference. The MKE mags feed ball 100%.
