Are shilens worth the extra money over a McGowen? Also, are the shilen select match barrels worth the extra $100 over their standard grade match barrels? I'm looking to have a bull barrel made in 270 for a long range/tactical build, that serves for medium-game hunting and varmint hunting.

prices (all pre-fitted to my specs)

McGowen Chrome-Moly - $270 + S&H
McGowen stainless - $299 + S&H

Shilen Chrome-Moly "match grade" - $345 + S&H
Shilen Stainless "match grade" - $374 + S&H
Shilen Stainless "select match" - $449 + S&H
