[QUOTE="MagnumManiac, post: 2106304, member: 10755"] With a mag box length of 3.7” and only the heal of the boat tail below the neck/shoulder juncture, I am at 3.610” with 210 ABLR, 3.635” with 210 Berger in one rifle and .010” different in another two rifles. All are high end Rem 700’s, Sendero, LR and 5R custom shop. This allows around 100fps gain over the same bullets in a 3.400” mag box. So, yes, longer seating allows higher velocity before reaching max pressure. Cheers. [/QUOTE]
