[QUOTE="CogburnR, post: 1241608, member: 29174"] There are some books that have that max, Bob Hagel's is one and possibly an early Speer. Original H4831 may have been a bit slower than current production.55g is probably closer to reality now. I had a RL22 load that was close to 3000fps with the 150NPT. 4000MR is supposed to be good also. Keep in mind most factory 130g ammo doesn't break 3000fps. As far as your velocity it could be that your chronograph was reading low, the rifle could have a slow barrel, etc. 130fps low isn't that big of a deal. [/QUOTE]
