So the 7-300WSM I have been fooling around with is nearing completion and I keep adding to the project and to the cost. I am having the muzzle threaded and a cap made with the idea of eventually getting a suppressor to play with on this and a couple of other guns. Given that the threading is going to be done anyway, I am thinking about adding a muzzle brake to the mix. This will not likely be used when hunting with the gun but would be helpful during load development and when wearing hearing protection is no detriment. The question is which brake and how likely is a brake to change the load the barrel likes? I would like not to get into a situation where I need two vastly different loads for with or without the brake. A simple change in zero point is not a big deal. The brake needs to be of the "untimed" variety because it is going on a Savage action and it just does not matter enough for me to ship the gun off to have it installed, I am just going to get it fitted when the barrel is chambered. Suggestions/comments?
