[QUOTE="Deviant, post: 1568554, member: 106404"] I had a 7mm WSM built 6 years ago with a 23" 9 twist Kreiger barrel. I could not find brass so I bought 160 rounds of HSM ammo and shot it to get brass and break it in. I am just now after 6 years starting to develop a load for it using 143 Hammer Hunters. I found a good velocity node at 3215 fps using 67.3 - 67.7 grains of 4831sc. I am .020 off the lands but my groups are around 1.5 MOA. Does seating depth have much effect on these? I was planning to do the Berger seating depth test next but maybe I need to switch powders? I know these are great bullets from what I have read here so I am just looking for advice from some of you who have loaded for these as this is my first time. The gun shoots around 1 MOA with HSM factory 168 berger loads. [/QUOTE]
