LMT MARS-H 7.62 PISTON, MLKMWS16PS-MARS

[Easy]

First post.
Just purchased a new LMT MARS-H 7.62 PISTON, MLKMWS16PS-MARS. Will be scoping within a couple weeks. No need for a can (for now).
I'll be shooting out to 400 yards (max); coyotes, large racoons, & the like. I'll try different ammo manufactures/ grain weights, but I'm learning that 168 grain may be the rifle's preference. Looks like 175 gr. may be an option too.
I would appreciate feedback from someone that has this exact rifle and can comment on ammo preference.

Thank you.

Very familiar with the rifle, and test fire and have a personal rifle in gas configuration. You are in the right area with 168 gr or a little higher, like 175 gr. We work with a number of military rifles, and you probably know this, but here is a good article on the M118 and M118LR rounds: https://snipercentral.com/history-m118-ammunition/
