No. The pawn shop from where Hinckley bought his (”Devastator”) bullets was from a pawn shop called Rocky’s pawn shop.
Hi. Did some looking and found the following from an NY Times story dated April 1, 1981 by Charles Mohr.
ATF traced the purchase of two Rohm RG 14 revolvers sold to Charles Hinckley on Oct 13, 1980 at Randy ‘s Pawn Shop owned by Isaac Goldstein. They did the trace in 16 minutes.
