MPA rifle chamber throat

[Jwhite225]

I have a question about MPA built rifles. Some of them have a label on the barrel that shows that it has a chamber throat for a specific bullet like the Hornady 140g A-Max/ELD. Would be harmful to use other weights and types of bullets or will it just be less accurate?

No.

Accuracy could be better with other bullets.

jump will be different for other bullets at factory ammo lengths

Like steel head said, no harm. With zero direct knowledge of the MPA chamber, but lots of experience with 6.5 bullets, the Amax/ELD will require more throat than say a berger 140 hybrid. So your eld chamber should accommodate everything.

The hornaday throat will be longer than the Berger throat, usually it’s like a .140 vs .190 throat.
