I use it for these reasons. Keep in mind i'm a hunter, and don't spend much time at the range. Once I have a load worked out. I don't change it.

No crud ring. That's a huge advantage to me for hunting.

No lube needed on BP threads.

More accurate than T7

Doesn't attract any moisture. Which makes the powder good to the last load in the bottle. No worries hunting in the rain either.

The most consistent powder I can use in a ML.

Recoil seems less that T7.

For me, the price is cheaper than T7. $27 delivered from Carlos. It cost me $24.95 plus tax for T7 and $12 for gas to drive to the gun shop.

For me, It beats T7 in every way. All the other subs and BP aren't even in the running.
