Use whatever cheap ammo is closest in bullet weight to your hunting ammo.

Heavier bullets require faster rates of twist (ROT) in the barrel’s rifling to stabilize the heavier/longer projectiles. Grits can provide details of what’s needed in the 7.62 selection of bullets.

Heavier the bullet, faster the ROT should be.

Also, the rifle's gas porting is set up for mil-spec 7.62 ammo.

The heavier bullets may start beating the op-rod.

Sorta like how the garand can not handle most commercial hunting rounds due to the oprod.  So u might would be better off with the 7.62 x 51 ammo then ?  Use hunting ammo in 308 sparingly unless down around 150 grain?

My friend has an M1A he’s been shooting for 25 years with NATO 147 grain ammo and commercial .308 with 150 grain bullets. 

I do the same in my M1 Garand that I converted to .308 years ago. 

A 150 grain hunting load will take cate of anything you encounter where you live. If it doesn’t you’re doing something wrong.
