[QUOTE="backwoods83, post: 1003788, member: 29890"] The above statement is spot on, the only true ways to gauge pressure in a WSM especially when using winchester brass is to measure the case head expansion or a strain gauge if you have deeper pockets than most. We have ran our 31" test barrel in 300wsm up to 3070fps with 230 grain berger hybrids, I won't get into details about how thats possible but I will say the OAL exceeds 3.2", but 2780fps is doable with 230 hybrids in a standard chambered 26" barrel and 190 vlds can go 2960fps so you are far from pressure. Just resize the brass with a slight (.002") shoulder bump and try it over again. You may want to give Imr4350 a try as well. [/QUOTE]
