[QUOTE="Idaho Trecker, post: 1487699, member: 67706"] This is with the adg brass. I'm thinking when I ran my first pressure tests with the adg it was on their first full load firing after a fireform shot that they weren't fully formed yet. The first go around gave me 2901 fps with a .2 grain less charge than the shots the other night that averaged 2997 fps and pressure was good. I haven't revisited 26 since but expect different results than from my first pressure test. I'm happy with 3000 fps and good pressure. I have noticed the barrel stays physically cooler with 23 than 26 which I'm sure would equate to more throat erosion but I'm not a scientist lol I've had good luck with 26 and temp stability but I've read some dont like it as much as 23 or 16. I'll stick with 23 for this rifle. [/QUOTE]
