The reason I mention this is that your gun (I believe) also has a 1 in 10 twist rate. This is not ideal for 150 grain 308 (milsurp and so on) but is absolutely perfect for Federal Gold Medal Match 168 grain Boat Tail Hollow Point. That specific ammo in my 308 performs best.
The reasons are many. (by memory) First, it's metal jacket is thin and soft, the Sierra bullets are very well made, with extremely small deviation between bullets. The microscopic hollow point is not for expansion, but for aerodynamics. The area behind the hollow point is empty, biasing the weight of the lead back aft on the bullet a bit. Leading to better flight characteristics over long distances. The boat tail is another aerodynamic feature. The brass, powder and primer are match grade stuff.
I'm not going to make the claim that this is the ammo your gun will like best. But I will say it's very likely to be a good choice for long range target.
The farthest I've shot my 308 was 600 yards (in reality, I can't see small targets that far away) and I was able to hit an old car hood propped against a tree with ease. Given time, I can get all of my rounds on to a the paper target at that distance.
I know there are people that claim they can hit a quarter at 1000 yards. I don't listen to them. I've been shooting rifles for 40 years and know the reality of the situation. It takes skill, practice, understanding the daily conditions, and the right equipment. Even then, it takes time to work your way into accuracy. Trust me, hitting a car hood, first try, at 600 yards ain't bad at all.
Your gun will do this with ease. It's very likely to be sub MOA accurate.
Thank you for your insight, I'll try and source that ammo, I don't recall seeing it but they can probably bring it in.
