i am quite partial to 22-250's, not to mention the 700 style action. i'd go with one if you can. this one i built in january already has a 600 round count and i just shot 1/2 moa 5 shot groups at 100 yards. i also put together a 4.75 inch 3 shot group at 800.
i shoot 33.3 grain rl15 with 70 grn berger vld's. i can shoot up to 75grn but the 70's do just fine.
at 585 yards i can hit a 8x8 inch plate all day.
i have a few lame vids on youtube of me shooting it. i just need to know how to edit video, or have someone go with me, so i'm not so winded trying to set up so quickly and take shots while winded, to keep the vids from being too long.
btw the light is 650 lumens and its bright. i can easily id at 200 yards with no moonlight. the mount i just whipped up out of aluminum and covered it with shrink tube.
