I ran the 310 Woodleigh in my 35 WAI at 2400fps with R15. Shot a hog at 30 steps, 40 cal entrance hole, 75 caliber out, soup in between, no blood shot meat! I killed a wad of PG with the 250X originally @2600 then went to the 200X @ 2970fps. That was with a 22" barrel too. But the most "useful" bullet I used was the Barnes 200X and then the 200TTSX (latter was never bloodied) I had the 200x going 2970fps. For grins I tested it sighted +3" @ 100 gave me -3" at 300! I killed zebra at 250 and Black Wildebeest at 347yds. I always hunted with it with a +2"@100, just held on the back of the Black Wildebeast. I still feel that for the majority, a 300WM is a better long range elk rifle. It hits hard, and is flat shooting.
