Little update. Honed a sizer, making ,432+. Think it will help. Tried the Unique load, no big improvement. Tried 5 each .430, .432 at 16 2400, .432 slightly better. Went to 17 2400 at .432, this target. Today I noticed oval holes, first I've noticed. Maybe need to bump charge weight more?
Still think part of it is the loose nut behind the steering wheel.

At large, whereabouts unknown.
I'm guessing that the old, old Contenders (Warren Center era) must have had better barrels. In my olde IHMSA days they were the standard for performance. Most guys shot jacketed bullets in my area, and they are more forgiving in some aspects. The BFs, Rocks, Merrills (I know they're the same), and others were just starting to get a foothold at that point (in my area). I did miserably at long range with my 30/30 Super 14, but won fairly consistently with my 357 & 30 Carbine Contenders in Field Pistol.

okay.
give it the old heave-ho and see what happens.
airc Ian uses around 19-19.5grs of 2400, I use 19.3 as a serious load in the 44.
IMO your fighting a couple of things here, one is pressure/velocity variances, the other is velocity is already on the edge.
almost the same thing but two different problems they are just overlapping.

19.2 with the Keith 240 solid and 19.6 with the 225 HP. It's about 95% of max in a Model 29. 16:1 plain base and a Federal standard LPP, any hotter primer and groups go to hell.
I can't remember exactly what upper end load I used with Brad's 287 but I think it was around 18 grains, which was about as much as I dared put in the case and the Model 29 didn't like it much. 17 should be plenty of pressure to make things work, but I agree with John that 18 should be fine. I don't think it's a load tuning problem as much as a follow-through problem and a bullet getting crooked problem....I see a consistent up and to the right stringing pattern. The bullets yawing is a sign of bad launch somewhere. Have you checked the crown?

I have a feeling your right. A self taught endeavor here. Maybe not a tight enough grip? I'm shooting with the forend on a rest grip in right hand, left cupping the base of the grip.

Rick can give way better advice than I can, but I can tell you that cupping the butt or even hanging a pinkie under it when shooting from a bench is bad form and will give you problems. You shouldn't have to give it the death-choke, either, doing that will induce wiggles. Let the gun buck, just control it the same way every time and your results will show on target. If we can tell you were right-handed from the targets.....there ya go.
That gun is not a chicken and you cannot choke it to death.
A tight grip is detrimental, does not take a tight grip, it does take a very consistent shot to shot grip and follow through.I can't see how shot to shot variation could be avoided with your left hand in the way of recoil.
Anything and I do mean anything that even slightly alters the way the gun recoils from shot to shot will severely alter shot placement, the longer the range the easier it is to see the effect of grip and follow through variations. The slower the bullet and the longer the barrel the more critical your grip and your follow through becomes because the bullet is in the barrel longer. The instant the primer fires igniting the powder the gun is under recoil, the bullet is still in the barrel but the grip and/or follow through are different for this shot from previous shots so the muzzle is in a different place on bullet exit than it was on the last shot. The bullet will go where the muzzle was on bullet exit, that may or may not be where your sights were aligned.
