Firming up.

I shot cast bullets out of my 22-250. I used pure linotype with gas checks. WW296 was the powder of choice. It was fun and challenging. In the end, I got a 5.5" 14 shot group at three hundred yards. Velocity was 2750.

Remington 700 VL.

It was a 300 yard prone match. Bolt was difficult to work because cases had only been neck sized. I stopped before finishing the 20 round string. Still my best cast rifle target.

That's NOT a bad group! I may be wrong but I thought WW296 was the same as H110 which is a magnum pistol powder?

I had purchased the lee hardness tester. Ended up deciding against casting for 223, for the proce Im buying jacketed bullets its simply not worth my time to cast for that caliber.

More than likely a GREAT idea. 22's are a pain to cast, powder coat and size in quantity .

In my unscientific methods of operation , AKA trial and error , I would mix the lead 50/50 with the type metal and test. This mix works well in 30 cal. rifles. 30-30 Winchester, 7.5 Swiss , 308 Win. , 30-06 and also the 303 British . Air cooled with gas check, at velocities from 1600 to 2000 fps .
Powder coating would up the fps range.
