It may have the same burn rate on the books but it certainly does not perform the same in my rifle for the same weight charge.
I get 2980fps with 760 and the 129 interlock with half a grain less than the 2940ish I got with the same projectile and 2209
Case life is also already better.

Haven't changed primer or seating depth so it must be a how. Not a how fast it burns thing.
The 123 Amax has an even bigger speed gain using 760 over 2209.

Accuracy with both powders is roughly the same.
