I only own a 303 and a 375 H&H and I do most of my practise with my 375. I must say it boost your confidence if you shoot better with the 375 than the 303 but then again if I ever get the bloody trigger fixed on the 303 I suppose they would be on par again.

The load I mostly use is the load that I use for plainsgame as well 270 grain hornady spitzer at 2550 fps.

I just love my "Maggie" all my friends that has shot with it before as well love it.
