Powder choice vs Barrel life

[Mulligan]

Is there an appreciable difference in barrel life in a Dasher or BRA between using a faster powder (H4895) and a slower powder (H4350/rl16)?

In other works, should I expect 1000 rounds of barrel life from a faster powder and 2000 from a slower powder? Does powder choice really make a significant difference?

Assuming velocities are about the same, and using the same heavy (105 class) bullets.

Barrel life in this instance, will be defined as holding the x-ring (1/2 MOA) in F-class (MR & LR).

Anyone?

I've shot a fair amount of RL16, RL15 and Varget. I can't say I've noticed any difference. RL16 is too bulky for the BRA.

In regards to the BRA and 4895 I can tell you my barrell has 1000 rnds on it for .008” of throat wear or lands moved forward.008”.. Maybe someone has a comparison for another powder with similar round count on barrell?

My 6SLR "moves" the lands around 0.002" every 100 shots with VV N160 and Molyd 105gr HVLD's

42.9gr N160 pushing a 105gr Hunting VLD @ 3150fps

There is a much longer and better article here on barrel life and how powder affects it. Also it has a much more up to date barrel life calculator on it that you can download. The only on Accurateshooter is very very old.
