Seems like a lot of headaches and work. I have 3 Savage’s I compete with. A 110 elite precision 6.5cm a model 12 BR and a model 12f class both in 6.5-284 Norma. All 3 shoot und 3/8” at 100 and .5 at 200 and 1” at 300. Yes some flyers from time to time. My brass prep is straightforward; clean, inspect and check clcase length within 2.160-2.170 (trim to 2.163 when required) size on Whidden FL bushing click adjustable with .091 bushing and .003-.004” shoulder set back with Lapua brass. Seat with a Redding comp die. I confirmed that my fired brass has outside neck .095 on all 3 chambers and loaded has .292 And I check concentricity of loaded rounds. All under .001” using Redding slant gauge. Load on a Lyman brass smith 8 turret press. (Some day I will get an area 419 turret press)
I was having similar issues and found the Whidden die to be the ultimate fix. My front rest below offered significant improvements over the Sinclair heaven varmint with windage top
I shoot off of a Farley gen 2 coaxial rest, 3” Edgewood bag and protektor bumble bee or flat DR bag (1.125 spacing for factory f class stock. 7oz trigger on all 3. Vortex golden eagle on BR and Nightforce Competition on f class. Yes the rest made a significant difference. But overall accuracy diff was from shoulder setback and neck size
My elite 6.5cm also shoots awesome when using Warne bipod and rear squeeze bag
I have found that savages do not like to be close to the lands. I use the COL listed in the hornady manual 2.880” which I recall to be 2.216 CBTO. i seat bullet and get the COL and then measure with comparator to get CBTO. I was told by savage to not push to the lands. Using ELDM 140g and 147g with either I4350 6.5cm H4350, I4350 or H4831SC 6.5-284 Norma
Personally you’re overthinking it. Consistency with reloads and practice. I also shoot every shot over a chrono every time I’m at the practice range. And have established loads with <7fps SD. SD will destroy groups
