shootist 43,
I have not shot the 120 gn barnes in 6.5.
I have had experience with the 120 gn sierra using 2209, primarily on feral goats in 6.5x55 and 6.5/06,
as well as the 100gn sierra hp on goats in 6.5/06.
in 6.5/06 2213 was used (not 2213sc) which had a burn rate like IMR 4831, a bit faster than h4831.
I cannot remember any loads, but do remember that the 06 case did not deliver the speeds hoped.
the 100 gn sierra was surprisingly harder than expected.
both bullets shot faster and flatter than 140s, and the game was light bodied, more suited to open mountainous terrain.
experience with barnes in 7mm led to my comment re the 120 gn 6.5 bullet.
suspicion is that it will penetrate better than privy, but offer less shock effect.
