Hey fellas, I've got a question or two. Figured this would be the place to go. I have two rifles I would like to adjust the triggers on. The first is a winchester model 70 in .300 wsm and the second is a Remington 721 in .25-06. Is this something that I can do myself or should I take them to a gunsmith? I can handle things mechanically,but this is unfamiliar territory. Any opinions and/or info is appreciated.
