Overview
Overview
The.30-06 JDJ is an improved form of the.30-06 Springfield cartridge designed for use in the Thompson Center Arms Encore platform. The body taper of the parent cartridge has been almost entirely eliminated in the JDJ design. The shoulder has also been blown forward considerably, with the angle sharpened to 60 degrees. These design features, reminiscent of the earlier.30 Gibbs, greatly increase the powder capacity of the cartridge over its parent. As a result, a 15" Encore pistol chambered in the.30-06 JDJ can safely equal the performance of a 24" rifle in the.30-06 Springfield. Quality Cartridge offers headstamped brass for the.30-06 JDJ, which can also be fireformed using standard.30-06 cases. SSK Industries currently offers Hornady Custom Dies for the chambering.
