Holland QD style brake, you don't have ports on the bottom so your dust print is less. You'll still have some blow back, but not near as much with a radial brake for prone shooting.

Brakes do their best work with big hitters 300WM, 30-06, 338 and so on. When you hear 60%+ reduction in felt kick they are usually talking about the heavy hitters. With a 22-250 you might be 10-20% less than the stated 60% reduction for your 200-300$ investment. (As a generalization, I know I'll have hate mail for this)
