My barrel life is looking to be a lot greater than a 6.5/284 with similar performance. In Ackley speak that is to be expected.
Mate has 2x 6.5/284s. Uses 139gr Scenars. First barrel toast quite early using 2209. Now he is using 2217 which gives as good accuracy and to date his throat advancement at the same round count is less than when he used 2209.
2217 may be too slow though for shorter barrels.

What sort of round count are we talking here, my experience being with relatively mild loads in 6.5x55 with 2209.
