Its right there with R15 and Varget, 4064, 2520, N140. I have some but have not found time to test it yet.

Thanks for the report. What is the barrel length on your shootin iron? Im looking to try it in a 6BR 30" barrel and a 30 Palma 308. Glad you got such good results, the only bad part is thats there is nothing left to blame its all on you now if you miss..... Ha.

Romulus said:That is some impressive load data. May have to get a keg now although I'm on an XBR kick at the moment. If you've used 8208 for similar loads what are you thoughts? I've found the 168-170 range to be its upper limit in my combos.
Do you have any case fill % numbers? I have 0 experience with RWS.
tclaunch said:I would put the burn rate closer to the 4895 variants than either RL15 or Varget. It is some very impressinve powder. Great going Alliant!!
jscandale said:I'll have to try it. I remember reading about it when it came out. I have been using RL15 for a long time, but I will be working on a new wildcat this week that this might just be a perfect fit for.

From what I've seen on Alliant's website, ARComp is faster than RL15, while PP2000MR is a tad slower. Since RL15 is one of the best numbers I've yet tried in the RAT, I'm thinking 2000MR could be a bit better yet.
I'm looking forward to more reports from shooters who're trying both these new numbers from Alliant....
flatlander said:Tank, What I've seen with most of the newer ball powders from RamShot & others is that they're not nearly as temp sensitive as most of the older, surplus ball powders like BL-C2, H335, AA2520, etc. Yeah, they're not as temp stable as Hodgdon's Extreme series of single base extruded powders, but there's been a lot of improvement over the years since the 1940s when ball powders were first developed.
And it's not just ball powders that are temp sensitive - any of the double-based powders - like Alliant's Reloder & Viht's N500 series - are more sensititve to temp changes than most of the single based extruded numbers. Obviously, there's a lot of shooters who're willing to deal with this factor - otherwise, we wouldn't be blessed with the wide selection of newer double-based propellants that are available today.
