I've loaded those kind of bullets for kids to shoot in 30/30s...

I've used Unique, Blue Dot, SR 4759...and several others...

SR 4759 was the most accurate...

8 to 10 grains of Unique, turned the 30/30 into a recoiling monster similar to a giant spitball gun... with the recoil of Grandpa spitting while chewing his chewing tobacco...

the kids sure loved shooting them and loved shooting a lever action, just like cowboys on TV...
