RL338: thanks for that link. I don't have any Norma 204 but it's very close to H4350 which is the powder the 175GTA liked. Maybe I will start with H4350.
Question for everyone; I've gotten real good loads with 180g Accubond and 175G Terminal Ascent in my 300WSM. I picked up a couple of boxes of Norma Bondstrike 180G and would like to work up a load for it. BTW: My Browning shot the Factory 180G Bondstrike pretty good but I thought I would try...
Joe, Good luck with the ladder test. I've ran the most tests with magpro so will be interested in hearing how the other 2 powders work. Long live the 270WSM.
It's not just me then. Well, the best group could be covered up with a dime and measured 0.162. One big ragged hole and 3 other 3 shot groups under 0.70 so it likes this powder and bullet.

Love my 270 WSM. Worked up a good load with 150g Hornady InterBonds for cow elk and thought I should try for a good 140G thin skinned load. Used Vit N560 and did a 12 shot ladder test and the whole group size was 1.326 with an average velocity of 3215fps. Next step is a few 3 shot groups to...
Finally got back to the range today with the 150G Interbonds. I worked on some 3 shot groups based on ladder test with Hunter and IMR 4831. I think I have a winner with this load of IMR 4831. Velocity was 3034 with no pressure signs. It was 50 degrees and a light breeze. I will play with...
