I just got a Rossi Lever action in 45lc. I also just got in to cowboy action shooting. I really like the carbine but most of the stages require 10 rounds in the magazine, the carbine only holds 8 rounds. My question is: Can one, safely, modify the magazine of this particular carbine to hold two more rounds? Or should I just scrap it and save up to by a rifle that will hold 10 in the magazine?
