I'm posting this for your safety, I didn't check the link but if you plan on reloading these be careful. They were never made to be fired at normal velocities like a full-sized 50BMG.

You'll have to down load them and probably use a case filler to take up the extra space inside the case. Try starting around 175grs and go up from there. 190grs should be used as the max loading, any more and they could be dangerous.

Keep an eye on them for signs of over pressure as you increase the charge. They're pretty awesome to see fly down range and them smoke when they impact on the target.

Anyway, have fun and be safe.

Cream of wheat, cotton balls, cotton flannel that's what you'll find posted pretty much anywhere you look on the internet.

No need to spend a bunch of money buying it from one of the big named stores on line.
