300 gr. ammo. The range was at the local Army base and was open to public on Sundays. Shooting positions were under a covered area and the blast would shake the concrete floor a few stalls around...especially the guy next to me trying to sight in his .22 rifle!
Wish I could find some video of that! The RO was okay with me shooting it even though .45-70 in rifles was not allowed.
Somebody ratted on the RO and my BFR got the boot!
