While H4895 is usable it certainly isn't an optimum powder for the 300 WSM with a 165 gr Ballistic tip, on the other hand H4895 is an ideal powder for the 308 Win with a 150 gr Barnes TSX.. Frequently when a powder is used that isn't a good match for the caliber and bullet weight low velocity isn't all that unusual. William
