The Power Pro-2000MR is interesting to me too because it's a flattened spherical powder which measures a lot more accurately than an extruded powder, and it comes closer to filling the case. Even though I throw pre-charges and trickle to my final weight I don't like the occasional crunch of extruded grains. Thanks for the info - I'll put it in my logbook.
Here's my latest 10@100yds with AR-Comp. The dot is 1". Could have been better because my eyes were fuzzing out and my aiming went crappy.

I looked briefly and couldn't determine what barrel length Speer used and I've assumed it's the standard 24" until I learn differently. I'm using a Satern 18", 1:8, 5R stainless barrel. My bolt is a Maxim. I really wish Alliant would run some Grendel load tests.
Speer used a 24" test barrel. It's on their website, but you have to dig a little.
