MarkS, good to see another fan of Benchmark. I'm really looking forward to trying it with the 90 gr Varmageddons when they finally hit the shelves.
12.5" BHW 264 LBC
107 gr SMK, GM205M
29.0 gr Benchmark (Hodgdon max) CM drop (no double weighing) 2440 with 5 shot SD of 7.
28.9 gr XBR (Hodgdon max is 29.8) 2473 with SD of 15. Notable ejector marks and the last time I'm ever going to bother with XBR in a Grendel case. I haven't ever gotten close to max with 3 barrels from 3 different manufacturers (BHW, JP, Satern)
