Rifle is Tikka T3x with 20" 1/10tw barrel.
I live in NC(<1000yds and 200-400ft elevation) and work in CO, but want to start taking mile shots with my rifle. I currently just shoot 180gr-200gr factory ammo but would like to start reloading with heavier ammo(looking at 208gr and/or 225gr ELD, 3.2" coal if needed). If I have my chamber set up for the 225gr, would this basically hinder my ability to run lighter factory ammo(which is where all of my brass comes from)? Any recommendations for other bullets?
Also, using the Berger calculator, it recommends 9twist for the heavier stuff in NC but is perfectly fine with 10twist in CO, would there be any noticeable issues with going to 9twist in the future(like noticeable drift, etc)?
I know there's a lot of compromises, but basically just wondering if my rifle set up for ELR can still fire factory ammo somewhat accurately at lower elevations.
