Casting and gas checks down under.
Afternoon all, I was just wodering if any one has had any experience with hard cast loads (gas checked) in either 7mm or 257. most of our reloading components come from the US and supplies are drying up a little so i thought i might give the lead a go. As I have always used jacketed projectiles, I am not sure what kind of performance is possible with cast stuff. Is it easy to make your own gas checks? any feed back is appreciated.

I stopped using gas checks years ago.
I keep my velocities under 1800FPS and put a dab of lithium grease on the base of each bullet before seating it in the case. Have never had a leading problem.
