Super Vel founder Lee Jurras, with Mag-na-Port's Barbara & Larry Kelly, early instigators of the big push to legitimize handgun hunting
David, with Warren Center and Ken French of Thompson/Center Arms, in Rochester, New Hampshire. At hand, the about-to-be-released Contender chambered for 7mm TCU (Thompson/Center Ugalde----"u--gaul-dee"). Ten inch tapered bull barrel. Upon release, T/C also introduced the Super 14----14" bull barrel to conform to IHMSA 15" limit for IHMSA Unlimited category.
7mm TCU tore a hole through Production competition in its inaugural year. Allen Kirchner downs a record 79x80 to become 1980 Production Champion. Kirchner's unorthodox freestyle position may never have taken a name but it, with 7 TCU in hand, brought home the bacon.
The three sevens: 7mm TCU, 7mm Remington BR, 7mm International (a.k.a. 7mm IHMSA).
* 7mm TCU----.223 necked up to .284. Fireforming blows shoulder out to 38-degrees. Easiest to load of all bottleneck cartridges. Mild recoil, even from 10" production barrel. unlike many wildcats, match accuracy from fireforming loads.
* 7mm Rem BR----basically a 7mm/.308x1-1/2" with small rifle primer pocket. One of Rem Bench Rest cartridges developed by Bench Rest Hall of Fame's Jim Stekl. Remington introduced XP-100 in 7mm BR winter 1979-'80 after Stekl and Bradshaw collaborated on final dimensions to meet silhouette requirements. Remington took forever to produce brass and load ammunition.
* 7mm IHMSA, 7mm International----Elgin Gates necked .308 Savage to 7mm and set back shoulder, with 38-degree shoulder angle. As 7mm BR brass required special forming dies and took beaucoup time to form from .308 brass, Gates and others reamed XP-100 7mm BR's to 7mm IHMSA. A BR chamber reamed to 7mm IHMSA leaves a ring on the fired case. A special ream die cleans the chamber for the "7mm Int-X." Richard Beebe at Redding makes correct sizing dies for straighter chamber.
Cherryl Hird nails husband-wife championship with T/C Contender 7mm TCU at IHMSA 1980 Internationals, as husband Skip spots.
Elgin Gates rechambered this XP-100 7mm Rem BR to 7mm IHMSA for Bradshaw, a short throat specified. Hornady .284 175 grain Spire Point over 30.8/H 4895 in Federal IHMSA brass, with Fed 210 Match primer, bullet seated to touch rifling, chronos 2050 fps. this pistol and load won the infamous Florida Sun Shoot sudden death shootoff, with three dead center heart shots on plaster ET dolls set on the ram rail. Prior to match, last three shots taken in Vermont printed 5/8-inch on cardboard chicken at 200 meters.
