Hi ya RedRock
Saw that you're building a 260AI.... I just got one going, finally got a good scope on it, will shoot some new loads when the snow clears some.
I did some powder comparisons with std vs AI, not sure I'd do it again. I need to do a water volume comparison, but doesn't seem to me like you get that much more powder capacity. At least, like the 257, 243, etc. But, is easy on brass as long as you lube your necks for resizing.
I"ll have to try some of the big BC bullets, albeit they are a tad big for pds. Some folks claim the 95 gr VMax's are the cat's meow, so far, they are only mediocre for me.
Keep us in the info loop on how it works.
Good luck, -West
