Well, I took that piece of junk to the range yesterday with some development loads using 168g A-MAX bullets and H4350, BL(C)-2, Varget and Benchmark powder. There was one loaded cartridge at each powder charge and charges varied by 0.5g one to the next.
H4350 was up first, 10 loaded rounds. All 10 went into one ragged hole an inch wide. BL(C)-2 was next, 8 loaded rounds. They also went into an inch, but I think there was 2 holes. (The target is at home, I'm not.) I left the Varget and Benchmark for another day as I had what I needed for the short term.
The H4350 loads will get used as the basis for developing hunting loads with individually weighed powder charges. The BL(C)-2, which meters very well, will be used for target loads. In the near term I hope to build a bunch and go to Whittington Center and work on the 500-meter rams. (The Remington .308 Win will be used for the same purpose.)
The long throat didn't seem to hurt accuracy to any great degree. Its another keeper.
