Just picked up a aac-sd with a aac brakeout flash hider muzzle brake combo already installed. Gun shoots great to 300yards(farthest Ive had a chance to take it out to so far)and Im about to start developing some hand loads for it. Im wondering what effects the brake/hider will/might have on the ballistics and accuracy of the round a fair amount farther down range? I plan to shoot it out to about 700-800yards, but would like to do some varmint hunting out around 500-600 so thats where accuracy will be most critical for now. The brake works great but I have no need for a flash hider if it has any negative effects on the ballistics.
