Thread: Powder for 6.5 06 and 140gr projectile

I'll run the same cases for a few reloads and see how many I'm getting before the primers fall out then if nesseccary back off a bit, maybe take it to 57.2/3

Jeez there is some shite on the net re this round, I wouldn't like to go much further but some claim well in to the 3-3100 for this powder out of shorter barrels, gotta be a load of crap.

Greetings Again Jakewire,
A load of crap, good description. The 6.5-06 is a long time wildcat that was popular in Australia and little if any of the data was pressure tested prior to the 1990's. Barrel interior dimensions are all over the map and the 140 grain projectiles are cranky with regards to pressure due to their length. Velocities of much over 3,000 fps simply can not be reached at sane pressures. You seem to have a good handle on this. 52 grains of AR2213SC produced 2,780 fps with a 22 inch barrel for me but only 2,630 fps in a 25 inch barrel for you and needed 2 more grains of powder to catch up. There is a system for estimating possible velocity for wildcat cases developed by John Barsness. Using this working up from the .260 Rem and down from the .264 Win Mag suggests a possible velocity of 2,950 fps for the 140 grain in the 6.5-06 for the softer projectiles. It will be less with the Nosler AB's and much less with the Barnes. looks like you are just about there. Hunting in 4 weeks?
Regards Grandpamac.
