155 gr Gold Dots AA#7 results a little slow!
I loaded some Speer GD 155gr over AA#7 this weekend and was a little disappointed with the velocity. COA 1.255", 80deg, Win LG primer (non-mag)
Lone Wolfe 5.15" Tactical barrel
These charges were weighed by hand individually so not thru a powder measure. What i cant understand is how the velocity is essentially unchanged from 12.3 to 12.7gr. Accurate lists 12.7gr at 1379ft/sec. I had to go to 12.9gr and my average still is not 1379ft/sec. Also, there were no pressure signs at all with any of the above loads.
I checked chrono with other ammo and factory ammo and it was spot on.
