[QUOTE="Wyosam, post: 2173006, member: 113713"] Played with a Bunch of powder in 7-08ai and 280ai 7-08ai 18” McGowan 1:8.5 Fireformed 1x Lapua. 130AH- Loaded to 2.815 (max mag length in Model 7) This rifle doesn’t seem to love this bullet, I’m going to try the 119AH and the 120HH 47 Gr Varget ~3040. Very low ES, but wont group under 1.5” 44.1 H4895 3000, Single digit ES, right around 1” (I’m calling this my winner right, will play with crimp to see if it settles down) Benchmark- ~3050 Also with low ES. Showed promise, but I’m out of this powder. I tried slowing them down, and running them up a little higher (pretty much all of them pressured out around 3075-3100), Tried a couple different primers, both MLR and LR. Can’t seem to tighten them up much. Rifle shoots 130 MK around 5/8”-3/4” (My minimal work up fireforming load). Tikka 280ai 22” Carbon Six featherweight, 1:8. Nosler brass- some new, some 1x All loaded to 3.30, My max mag length. This one was a little finicky, too. Anyone finding the AH a little tougher to tune than the HH? 140AH- Never did get this one to settle down. RL16- Got crunchy around 3255. This ladder shot a 4” group, with no two close together. H100V- Maxed out around 3320, again scattered all over the place. H4350- Topped out around 3220, accuracy slightly better, but not worth pursuing. N555- right around 3200. This was the closest I got, still well over an inch. I shot some 168 noslers to verify the rifle was still shooting occasionally during all this- still cloverleafs. 155AH RL16- ~3100 low es, around 1.5” N555- Got around 3170, never saw pressure but was very compressed. Around 3100 shot a little over 1” H100V- 3100ish, again in a shotgun pattern. I know a lot of people are having great luck with this powder, but my rifle is not a fan. Decided to try a slower powder just to see what these did, since they seemed to shoot better at the lower end of the above ladders anyway. RL23- Started mid 50s, ladder suddenly tightened up about 2900, and then started stacking them tight up until I ran out of room. Only 2985, but shoots cloverleafs with single digit ES. It will be interesting to revisit some of these when this barrel speeds up. I‘ve not played much with the AH until now, too many other projects. Compared to the HH, they sure seem to be more finicky. I guess I got spoiled with just shooting a 3-4 grain pressure test into an inch pretty consistently. Of course these are both also new barrels, so who knows. [/QUOTE]
