[QUOTE="HARPERC, post: 629195, member: 30671"] Just to keep the discussion alive-To say he gained 200FPS due to the 26" barrel is a bit simplistic, lots of factors involved-pressure as you mentioned. If you trimmed that 26" barrel to 22" my bet is it cracks 2500fps. I pulled up loaddata.com just to peruse a variety of rifles, and keep the source neutral, they list a load with N-205 that clocks 2571with a 220 grain bullet in 22". In a 24"barrel R-22 2602. The 30-06 does not benefit a great deal from longer barrels. It's been forever since I loaded the 220's so I don't recall the loads, but 2500 FPS with 220's wasn't that tough to do in a 22" tube. The 30-06 biggest deficiency is manuals that hold pressures low in consideration of older rifles, not barrel length. [/QUOTE]
