My T3 loves 43.0 gr. of Varget pushing a 140 gr. Gameking in Lapua Brass
A question about your load; have you fired it over a chronograph to see what your velocity is? My reason for asking is this. You are at book maximum as listed by Sierra using Federal brass, but you are using Lapua brass which is substantially thicker and heavier than Federal. In my experience, I have had to reduce my powder charges by one and a half to two grains in Lapua brass in order to show the same velocity (thus pressure). May just be me and my rifles, but others see these loads and assume that they are ok to use as listed. Just thought it to be a question worth asking.
