Snipershark you build whatever your little heart desires. As Jim said Barrel and stock or if you can open your stock up enough just the barrel and tools.

Robinhood maybe he wants his next hog to have a bigger hole on both sides so it can drain better. Thats why i have a 338fed and a 338-06. I like big holes and there is no such thing as overkill. Excess force maybe but overkill never.
