I want to work up a ladder with AR Comp and 123 Scenars for my new JP 22er but haven't seen any published data on the World Wide Web. XBR didn't give me much velocity before the accuracy node started widening. CFE 223 gave me some results to pursue further, but man that stuff is messy to work with.
It appears like the low 28s is about as high as guys have gone, which would lead me to believe that 28.0 is around where a published max would be and the area to approach with caution, and that 26.0 would be a good starting point. I'm not chasing velocity - getting 2550 would be good enough for me (I'll of course take more without pushing the envelope). Will be using Lapua brass, GM205Ms and seating at 2.24
Also wondering if anyone's tried AR Comp with 129/130s. I have a partial box of Accubond LRs gathering some dust and figure that since Alliant says AR Comp is good for heavies in 223 and 308, the same may hold for Grendel
