quick question your 43.6 load shows an ES of 82 fps is this correct? 83fps will show up on the target.
No the 2,503 was actually 2,583 which equal 23ES. And I know how to hold a heavy bullet rifle. Been shooting 208's for over a year and a half. But have never grouped 3 that nice and then have 2 fall out like that before. And on 2 consecutive loads.
I am not disputing your ability to hold a rifle but you are not alone when it comes to grouping 215's, speaking with other top tier shooters they have commented they can get 5 - 7 - 10 shot to group together only have 1-2 vertically out of the group.
My load work up had similar results as you, off of a bench during seating depth testing i could get 3 shots to shoot flat repeatably. going prone and getting setup behind the rifle the load that shot so flat off the bench would group two tight and then shoot the 3rd into the next county. fidgeting with hips, shoulders, grip, cheek all influence my recoil and shot location. if you know the gun shoots and the ammo is good that leaves only one other variable.

Welcome to the world of managing recoil of the 215... consistency wins out. The same recoil pulse with the same crosshair movement will show up as tight vertical. crosshairs moving straight up and down and the next shot moving to the left will show vertical. Or in my case really locking down on a shot will send a flyer (8 ring) high
??? Would you please explain better? Thanks
When you shoot a string each shot should break like the last. Your crosshairs should move in the same direction and cadence every time. Lighter bullets seem to be more forgiving with recoil and small variations are not as apparent...the gun moves less and with higher velocities has less dwell time in the barrel which resulting in less disturbance of your sight picture and consistency shot to shot.
when shooting any weight bullet your rifle system should be set up so that the cross hairs stay on your target ideally the reticle should stay within the black circles. (this is easier with lighter bullets)
When shooting the 215's you have more recoil slower speeds, longer dwell time in the barrel and the entire system wants to push you around. controlling the reticle takes more concentration and effort. When you shot and the crosshairs move in the same direction and cadence even with the 215's your grouping tightens up and you can rely on your shot location to be true of your wind call. If your crosshairs move in the same direction for the entire string (regardless of the direction) you can be assured that your grouping will be tight and your wind calls will be consistent.
the problem is the 215's are not forgiving, a small change in your position will show up in your recoil sight picture
I will give you an example i shot an 800m match 900 yards last weekend with the 215's scored a 74 8v (149 8x) 14 shots had the same recoil sight picture 6 to 12 straight up and down for that one shot the crosshairs broke left. My aim was the same i thought my shoulder, cheek, hips, and NPA were the same but the recoil told me something was different. that one shot was a solid 9.
on a separate relays during that string i would consciously move my shoulder into the rifle each time i would do that the rifle's recoil would change and I would lose the shot.
