Ok, so Ive got the bug to build a 7mm for noting more than shooting steel plates at 250 - 1000 yds here at a central oh range. I've got the candidates narrowed down to 2 rounds right now. 7-08 & AI and the 284 win. I know the .284 is a hammer at the 1000 yd game but the little 7-08, esp the 08 AI intrigues me. Does anyone have some real life trigger time with the 7-08 AI round in particular? Both have their merits & Ive read up on the 7mm's on accurate shooter but the 7-08 info is fairly limited. Any and all info on the subject is welcome. I'd like to shoot the 162 amax and berger 168/175/180s out of my unfinished # 29.5 inch barrel. Would a 28 inch finished tube be perfect for squeezin out the max velocity in the standard 7-08?
