Noticed that there are a few videos of people modifying their Remington 700 by getting it "Bedded". Does anyone know if the Remington 700 really necessary to get it bedded for accuracy purposes?
Nope. Bedding, generally speaking, is a way to improve accuracy. But honestly, unless you are shooting prairie dogs at 1000 yards, bedding a hunting rifle is a waste of $$$. You aren't interested in punching tiny groups at long distances, you're interested in placing one meaningful hole at close-to-moderate distances.
You may want to seriously consider a synthetic stock, though. As much of a fan as I am of wood stocks, the humidity and rain encountered when hunting can easily warp a wooden stock. You might start the hunt with a perfectly sighted rifle, and by the time you get a bead on your pig, have a rifle that shoots 6" to the left.
Unless you do get an old milsup battle rifle. The stocks on those are so impregnated with oil, I bet they would survive a year under water!
