338 lm berger 300 otm

Berger has some data around for that. Charges lower than typical, but they listed a short oal iirc... last rifle i had those in needed about 3.9 inches oal on the cartridge to be near lands.

They shot very well single loaded but poorly at that rifles short mag length. I did get pressure signs earlier than typical as well with them vs 300smk etc.

Just something to look out for if your rifle is like mine was.

I believe berger said about 85.0g as the max charge for 300 otm fwiw.
