130 Hybrid Not Feeding In Mega Maten 6.5 Creedmoor

[DRAM40A1]

After finishing up load work on the 140 AMAX, I turned my attention to the 130 Hybrid. I started them out .020 off the lands at 2.822
With a ten round KAC, a 20 round KAC they jammed at the end of the barrel before entering the chamber. I seated them .040 deeper to fit in a Magpul PMag and get the same results. Any advise as to what is causing this issue?
I’ve pretty much given up on the Bergers and just about ready to move on to 139 Scenars....

Try flaring the front half of the feed lips on mag *slightly* upwards (last 1/2" or so flared upwards maybe 1/32-1/16" of an inch.). It should allow the case to rock upwards just a bit earlier and avoid hitting edge of chamber.

Some have enlarged the feeding cone when they've had similar issues but easier to try a mag fix than machining new feed cone.

Can you try a different mag? PMAG? Or will you have OAL issues?

I used 10 and 20 round Knights Armament mags. Plus I seated them deeper to try the PMAG. I’m wondering if I should try .010 off the lands and seat them a little longer. I guess it wouldn’t hurt to try.

BTW, all of my mags feed 140 AMAX, 140 ELDM, and 139 Scenars with zero failures.

I don’t know why I though longer would help. LOL
I’m going to try and adjust the feed lips on one of the mags.

Issue is the Ogive shape vs ogive to tip length. The 130s are very flat,skinny from ogive to tip and relatively long (140ELDs etc are more like a short half football shape vs 130s are more long triangle shaped).

The ogive on the 130s doesn't contact the feed ramp enough to to push the nose up into chamber.

Modifying mag slightly should help though; get the bullets to ride a bit more nose upward in the magazine and it should solve issue.
