.223, CBs and assorted powders

These targets were shot with cast boolits WITHOUT gas checks.
I'd like to thank X101Airborne for providing the boolits for these tests.

Nice work.

Jim, is that a Lightweight, or a regular barreled rifle?

have you done anything to it, like they suggest on GBO? ie/O-ring?

I have one Lightweight, and I'm going to play with it this spring. one of the things I'll try also, is an Oring on the barrel, to tune it like a .22

I LOVE single shots

You're going to have to educate me on the O ring thing, I'm not familiar with that.

You're going to have to educate me on the O ring thing, I'm not familiar with that.
With the forearm off, observe the stud mounted in a dovetail on the barrel. Go to your local hardware/plumbers supply store and get a rubber o-ring 1/8 thick or slightly smaller that will snuggly fit over the the barrel stud . Reattach fore-end and you
have just floated your fore-end and just about can guarantee much better accuracy.

[Jim]

Interesting! Thank you, I'll look into that!

I just discovered that 11.2 gr of 5744 gets me a group under .9" at 40 yards with iron sights on a T/C carbine. I can't ask for better with my old eyes.
