I would like some help and advice on a new build that I am thinking about and would prefer first hand experience if possible. I have a couple bolt action smith built rifles in 6.5mm, 7mm, 22lr and I am looking to build a Bolt Gun in 223 / 22-250 / 22 Creedmoor / 224 Valkyrie something along these lines or...? This will not be a Comp Rifle just a Fun Gun, I would like something that I can buy Brass ready to go and not have to fire form. What would you guys build to shoot 75gr - 90gr Bullets around 2,700 and Up that would have the best barrel life considering how hot it was run. I shoot a lot but not competitively so I don't want something that gets 900rds and the throat is toast. There are so many new rounds out that Im not sure where to start, really looking for help on the caliber and tying to find the best all around and yes I know that's asking a lot.
