CCMDOC,

Excellent report and well done all around. From Decision to purchase to downing an elephant and everything in between;)
It looks to me like you had a loaded some GS FN Solids? I also have a 577 but I haven't been happy with woodleigh solids performance... So I've ordered GS 640gr FN. If you have used them or worked up loads using them in your 577 I'd really appreciate it.
Regards
Leon
