Saw your thread on the 350. I get .5 or better with the 350. I load for a friend who was ringing steel 6" steel at 300 with his. Your load came up with 43,800 psi in GRT so it should have been safe. I agree that you were in the lands. A lot of good info in the thread but I'll add a few things.
1. Case length is absolutely critical to accuracy because the case headspaces on the mouth.
2. Use a Lee factory crimp die and apply a firm but consistent crimp on top of the PDR band. Much better with the slow burning powders. (better ignition)
3.While Lil-gun gives good speeds, it didnt give best accuracy in my friends Savage. It gave .5-.6". 2400 powder shot under .037" and 11FS powder shot almost as good. Another friend who reloads himself uses Lil-gun and best he can get is .7" out of his winchester rifle.
I tested with H-110, 11FS, 5744, Lil-gun, 4100, and 2400.
The 350 in a savage is capable of amazing accuracy as you've seen. Keep at it
