Re: sierra load data
I have found sierra's loading data to be very conservative also. However I do use there data alot to get a safe starting point and work my way up to the max my chamber will allow.

Currently IMR 4320 is my load for that bullet. I'm using Hornady match cases and Winchester LR Magnum primers.
