[QUOTE="MontanaMarine, post: 23830, member: 268"] Thanks for the info Darryl, I've been shooting 190gr SMK moly in my 30-06 at 2903 fps with 63gr RL-22 in Norma brass. I get pretty consistent .5 moa accuracy. My barrel is 26" #7 Douglas 1-10 twist. I've been contemplating trying the 220 or even the 240s. I've heard they do pretty well at 1-10 twist, despite the 1-9 recommendation from Sierra on the 240s. Guessing I could achieve 2650-2700 with the 220s, and 2500-2550 with the 240s. Probably using around 61-63gr of RL-25. If i can shoot 240s accurately at 2550 fps, it should hit at 1300 yards with about the same velocity as your Tomahawk at 1800. And with a mechanical accuracy of .5moa, I think that gives it potential to that distance. I need to nose around at Weapons Training Battalion and see about getting on the 1000 yd range on the weekend. I guess that is the only way I will really know. Do you think I would be wasting my time with the 220-240 gr matchkings? MM [ 11-21-2002: Message edited by: MontanaMarine ] [/QUOTE]
