[QUOTE="RockyMtnMT, post: 1198524, member: 7999"] We loaded my Uncle's Browning A-bolt 22" barrel 30-06 with the 181g Hammer Hunter with 57g H4350 for a vel of 2830fps. Another 4" of barrel may give 25 fps per inch. Would get you very close to your desired vel. Generally because of the PDR design on the baring surface a bit of vel is gained due to less friction in the bore allowing a bit more powder and vel. HBN coating will take this farther yet.
