[QUOTE="elkaholic, post: 2326500, member: 13833"] Update on the 300 MEGA. Finally got a 300 running. Ill let the builder post most of the data so I'm not accused of exagerating😁 Very early results with WW brass and a 215 Berger running above 3000' with H1000 and no pressure signs to speak of but out of capacity. (Probably near max with WW brass though) 26" barrel. RL 26 will no doubt run above 3050 even with WW brass, and likely near 3100' with ADG. ADG head stamp coming in December. So far the 7 mm and 300 are running at or above predicted! The 338 will be least likely to make predicted, but we'll see? I knew it would be the most difficult to break 3000 with a 250. My 7 is running along shooting .2's at 3180 with 175's and going strong at 8 firings on brass🙂 [/QUOTE]
