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.
