This is my first post and if it is a duplicate I am truly sorry, I have been searching and couldn't find any thing that was related. I am about to purchase a my first bolt gun in 308 for long distance shooting and I am having difficulties making my final decision. I have cut it down to to 2 choices the Remington sps varmint and the sps tactical, have heard that the stock sucks on both so I will be replacing them pretty much as soon as I buy the rifle. Excluding the stock the only stock, the only difference is the barrel length(varmint-26 inch tac-20 inch). I will mainly be shooting 600-800 yards. I know that the 308 has a 30-50fps gain per inch depending on the ammo, I also know that a shorter barrel is more rigid so I am at a stand still. At a distance of 600-800 yards will the drop in velocity be a big factor? I am also not against the idea of buying the varmint and then cutting and re-crowning the barrel to a different length. Any insight that you have would be greatly appreciated especially if you own either rifle.
