The rem700 with a Wyatts extended box mag or a savage will accept a 2.995" oal and feed from the mag. The problem with 185-210grn pills is that a Saami spec 308win chamber needs about .060-.075" more throat to keep the bullets out of the powder space. The 185 hybrid can hit 2600fps from a 20" barrel with CFE223 and good match primers but case life will suffer. 2800fps is easy with a 26" barrel and RE17, RE15, AR comp, 2000MR, CFE223, W760 with mag primers, etc... With the proper throat length the 208 amax or 210 berger can be pushed to 2700fps with a heavy charge of RE17 and Fed210Ms in a 26" barrel but the 308 was never really intended to shoot lead over 175grns, but anything is worth a try.
