I met an older gent at the range yesterday who professed he'd been a Weatherby guy his whole life, but has been tired of the poor accuracy from the ones he's purchaced these later years. He's has custom barrel installed on Remingtons the last couple years and said he's never going back now, period. Now, I've never owned a Weatherby so I can't say. I just never have liked their gazilion bolt lugs and looks of the rifles they offer, plus my dad has always told me they're a *** and has seen them fail to function on several occasions while hunting, and he said they were the only brand that he ever did personally see fail in all his years. He'd never own one for sure.
Set more time aside to shoot, or keep the range limited, it takes much trigger time to be certain of your drops and your abilities being repeatable.
That said, perfect practice and much of it at long range with only a 1 MAO capable, and repeatable rifle will ALWAYS blow away the tack driving .25 MOA rifle if you practice little with it at LR.
Perfect practice takes time, and ammo, and unless you're willing to nail down and guarantee yours and your rifles capabilities as you increase your range, with BRUTAL honesty, learning what all the variables are and how to correct for each of them, LR accuracy and repeatability will a hit and miss and you'll just be kidding yourself in the end.
You have come to the right place to learn more, as most ALL of these guys will NOT feed you BS or worthless drivel but rather help you learn the ins and outs of LR in leaps and bounds.
Have you considered using a doner action and rebarreling it with a custom barrel? 90% of your accuracy will come from the barrel itself so, a barrel from one of the top MFG's is biggest step in the right direction for the ultimate in accuracy you're likely to take, you pick the action....
If you're even considering spending over a grand on a scope, I'd snatch the Nightforce 5.5-22x56 with the NP-R2 illuminated ranging reticle in a heartbeat.
