Just got my 762 SDN-6 and have only shot some hand loads. The chrony registered 1050 fps with 220 grn jacketed over 10.5 grns of 4227. My question has to do with the noise level. Some of the reviews I had read talked about the action noise was the loudest sound that could be heard. I am not getting that. Distinct crack is very noticeable.

I am wondering if a slower powder, like H110 will quiet things any better.
