    Is anyone out there reloading for a 7mm WSM with a BOSS, any details that you might have to get me going in the right direction? I’ve tried a few different things and my rifle might just be finicky but I can’t seem to get much to group very well in it. So, load data and also BOSS setting would very helpful. Don’t worry, I won’t take your load and just shoot it, I’m start at least 10% below and work up watching for pressure.
