300 Blackout

[igot105]

Has anyone tried loading 300 Blackout rounds using the Xtreme 30 caliber 110 grain round nose plated bullet? I tried xtreme's 150 grain 308 flat nose bullet but had difficulty with feeding issues (even testing with several different magazines). If using the Xtreme 110 grain bullet to load 300 Blackout rounds, what charge are you using if using H110 powder? Thanks

Yes I have. If you have a M-4 feed ramp anything but pointed bullets will have trouble.
I hear you can file down the sharp edges or just use a printed fmj

I haven't tried those but I did try .30 carbine bullets, wouldn't feed properly...

I have, it got stuck every other round. Pain in the ***.

I have had a similar problem with supersonic rounds through a magpul mag. Sub sonics work fine. My impression is that this is a col / oal issue with the magpuls. Running through a metal stoner mag the problem appears to have disappeared. Trying to take some time to test this further today.

I run the Speer 125gr TNT with no issues. I have also run the Hornady Vmax 110 with some minor issues.

Follow up. Can't in good conscious fault the magpuls. Must be col issue.

If you are looking for inexpensive bullets I've had good luck with 135gr or 16gr 30-30 coated bullets. The chamber fine and shoot good.
