I use the Remington 150 bullets and H335. Lyman aperture sights on a Win. 94.
Shoots about 2 1/2-3 inches at a hundred.
In the past, I've also had excellent results with H322 and IMR 4064.
In 170 grain bullets, my best results were with the Hornadys and IMR 4064.
H322 and 170 cast linotype bullets at about 1500-1700 FPS make great plinkling loads in the .30-30.
If you think a mighty military force is expensive, wait 'til you see what a weak one costs.
