I shot 40 rounds through my 375 H&H today, recoil was not a factor, but my 375 is definitely too heavy. I did notice that if I didn't hold the forearm tightly with downward pressure from the becnh, the recoil off of the sandbags would change the point of impact. It seemed like the barrel was moving before the bullet left it. I've never noticed this with my faster shooting, lighter recoiling 270. Once I kept downward pressure on the barrel by holding the forearm tightly, it sighted in and behaved like my 270 does (without doing any of that). I was shooting 250g Swift A-Frames at 2760 fps (my elk load).
