Many years ago, LSA President Dan Zelenka introduced me to perhaps the best all-around wildcat cartridge for the Thompson\/Center Contender pistol: the 6.5 JDJ. With a 120 gr. bullet, mid-sized game don\u2019t stand a chance. Even African plains game fall to its punch. The cartridge was developed by famed gunsmith and founder of SSK Industries, J.D. Jones. The 6.5 JDJ is based on the rimmed .225 Winchester, which is necked up to 6.5 mm (.264\u201d) and fire formed to produce the finished case that has about 7% more powder capacity than the parent .225 Winchester. This increased capacity results from the 25\u00ba shoulder, which is located 1.530\u201d forward of the base in the .225 Winchester, being pushed forward to 1.630\u201d in the 6.5 JDJ at an increased 40\u00ba angle.<\/p>\n
When working with .225 Winchester cases, a single pass through the 6.5 JDJ die expands the case mouth to accept a bullet of .264\u201d diameter.\u00a0 After priming the case with a large rifle primer, a medium burn rate rifle powder like IMR-4320, IMR-4350, H-4831, or IMR-4831 can be used with a 10% reduction from the maximum charge. Typically, I use 140 gr bullets to fire form the cases, but any .264 bullet can be used. Fire forming cases is fun, and you\u2019ll likely find that the reduced charged cases are very accurate, although perhaps not a great choice for hunting given the reduced powder charge. <\/p>\n
But what does one do when there is a nationwide shortage of reloading components, there are no .225 Winchester cases to be found, and there is no production of obsolete cases on the horizon? Well, short of paying $5.25 per case to a boutique custom brass producer, one searches the amazingly useful The Handloader\u2019s Manual of Cartridge Conversions <\/em>by John J. Donnelly. According to Donnelly, .225 Winchester cases can be produced from .30-30 Winchester brass. I just happen to have a pile of once fired .30-30 brass laying around, so I headed out to the reloading shop.<\/p>\n
