I have been thinking of switching over to the 22-250 for my walking predator varmint gun. This would take everything from crows to cougar. What are some of the advantages and disadvantages of the 22-250. I dont do a lot of fast hot volume shooting. On a busy day I might shoot only three to five rounds. I know most 22-250 are a one in fourteen twist. Whats the heaviest bullet that can be stabalized in this round.
