re: Teach me about WSM's

They claimed more efficiency when they first came out, but there was a guy who wrote an article in G&A back then who was very skeptical. There is the advantage of the short action rifle, but they still have 24 inch barrels, so the gun is not that short. If you shorten the barrel more than that, you lose the benefit of the extra powder. They are good cartridges that deliver a lot of energy.
