I have a Sendero SF in 7 RUM. It's recoil is very fast and sharp. I have been shooting a Sendero SF in 338 RUM. It's recoil is more, but not as quick. Both of these rifles compaired to a BDL in '06 is very harsh. I have shot a stock 300 WSM SS Syn with factory ammo that would make your eyes water, worse than an old 300 Wby with the same weight bullets. So I guess all are different, but when you get into the "MAG" class, expect to get hit. I have found brakes, like OPS INC, help me fire more accurately.
Good Shooting,
