This is a two part question. First, I'm wanting to get a 338 lapua rifle, I'm mainly a savage guy( mainly the trigger), I like the look of the 110 ba stealth (stock adjustments, middle brake ect.) But it only has a 24" barrel, all the research I've done long range shooters prefer 26-28". Debating to get the gun and put a longer better barrel on it to take it to is full potential or just use it as factory barrel and never know how much better it can be. Or get a savage model 112 magnum target, and replace the buttstock with something I like better. Part two, optics. On my savage model 12 benchrest 308 win is a nightforce nxs 12-42×56 0'd at 600 yards, I love this scope wish I could get another and put it on the 338 but it is discontinued. I like what I've seen and read on the nightforce competition 15-55×52 but do I put it on the 338 or take the nxs off the 308 and put it on the 338 and put the competition on the 308. I rarely hunt with that 308, it is usually my benchrest gun, the 338 I probably will do more hunting with. Also the 338 will be zeroed at 1000 yards probably. Thoughts?
