The 7WSM is an excellent cartridge. I am not really spun up on the ADI powders, although they are supposed to be derivatives of Hodgdons powders. The 160gr Accubond is a great powder and you should be able to get 3K out of your rifle without an issue. I am a fan of a good muzzlebrake. They reduce recoil, assist in making better shots and let you get back on target pretty quickly. I know they aren't for everyone, but look at the KDF, HART, and some others. I wouldn't mess with Magna porting, just my opinion, but a good brake is a very useful shooting tool. If you are already wearing ear pro, you are ahead of the game. Good luck, throw some pictures up if you can. Scotty
