I am currently working with the Berger 185 in a 20 inch barrel 308 put together with parts I had laying around. This barrel has an extremely long throat. I have decided to seat the bullets into the lands and so far shot the 175, 185 and 190 Berger bullets with it. I started with my accuracy load of 45g Varget and the 175 bullet. Then 43g Varget and the 185 and 195. All went into the same hole, a .8 group for 13 rounds. I have upped the ante with the 185 and in half grain increments gone up to 45g Varget. These 5 shot went into a .5 group without any pressure signs so now have loaded 5 rounds from 45g Varget to 47g. Need to get to the range to shoot these and see when I start getting pressure signs. All shots were at 100y. I chono'd the initial (43g) shots and got 2571 with the 175's (45g), 2437 with the 185's and 2422 with the 195's. It is interesting to note that all the bullets would have gone into the same hole at 100y had I shot them all at the same time.
