Hmmmmmmmmmmm stalking huh? ok then weight will make a difference , your 338 should not scope you if the scope is set up right but in any case you do not want more than a 16 inch barrel you can kill a hog sized target to 450 no problem . keep the accessories to a minimum use a carbon fiber hand guard and I would use a carbine stock makes it alot easier to adjust for clothing or a pack or whatever, put a ACC brakeout on the end and get to killin hogs this is no rocket science shoot 168 barnes TTSX and you are good to go you could build the whole thing for under 2 grand, it will look kinda like this and it will do this... all day long.
