Re: which one? -ruger 7mag- wby 280-wby 338-378
I know Rugers aren't the top choice for precision long range rifles, because of their actions (I believe). However, once you throw some money into the gun in the barrel, action, trigger, and stock, I am sure you could have a pretty slick shooter.
Someone with more knowledge and experience will chime in I'm sure.
