MPA BA Chassis magazine issues

[dbow]

I am having issues with an MPA long action chassis dropping the mag under recoil when rounds are in the mag. When it’s empty it stays latched just fine.

Rifle is a 300prc, using CIP+ mags. Mag latch is adjusted to have the mag just below the bolt. Not sure what to try to keep the mag securely latched.

Any advice would be much appreciated.

If you insert the magazine and then pull down on it does it come out? It sounds like the mag isn't latching in completely.

It is latching when inserted. I can hear a positive click from the latch when inserting the mag. I can’t pull the mag out without releasing the mag latch

Any chance the mag catch is hitting something under recoil?

You mean is the release hitting something under recoil?
If so, no that’s not happening. I’m shooting prone on a mat with a bipod and a rear bag. Nothing else up by the mag area.
