We fireform the 416 HSM with 65 gr of medium speed
surplus powder, with rest of case filled with farina
and grits mix, with a play dough plug in the neck.
It is loud, so we shoot it into big container through a barrel size
size hole, so the sound is muffled, so it doesn't deafen us..
It is great getting more companies making 416 caliber bullets,
long target and bore rider bullets. Ed..
