I have the same rifle and have found it likes a 68/69gr bullet the most. I made a bunch of loads from 50 gr fmjhp to 75 gr bthp and the 68 gr Hdy bthp and 69 gr Sierra bthp worked the best by a pretty good margin. With those 2, shooting off a bipod I can get 1" groups at 100 yds. (Harris bipod, Bushnell 6-24 scope using a rear bag.) Anything heavier seemed to open up the grouping quite a bit (maybe unstable, not really sure). Lighter, the only thing that came close was a Hdy 52gr bthp, but it wasn't as consistent as the 68/69 gr.
Overall, a well built gun for the price. Very easy to shoot. I like the full length top rail and that the little side rails come off. The little bottom rail is handy for bipod mounting. I like the forend way better than a typical quad rail - much easier to grip and hand on to.
Cycling has been great, very smooth, no issues whatsoever though prolly 800+ rounds to date.
Ilike the QD mount point in the end plate for a QD sling or ring, nice touch. Stock is cheap-ish MOE variety, it'll get replaced with an STR/ACS soon enough (for better cheek weld). Overall I really like it and it runs very well.
