my little 336Y, with the short 16 inch barrel will shoot 5 shot groups into an inch all afternoon. Thats using my handloads, a 170 grain Speer FP over 34.5 grains of IMR4320. I use an older Redfield 5 Star 20mm scope, a 1 X 4 Variable.
My Savage pump, a Model 170, shoots as well, with the same ammo. That rifle has another Redfield 5 Star 20mm scope, this one a 2 X 7 Variable.
I am looking forward to trying some of the new Hornady soft pointed tip ammo, to see how accurate it is. That should extend the range of the 30-30 quite a bit for deer hunting.
