[QUOTE="Firpo, post: 4157116, member: 45550"] Can’t say that I’ve developed any wildcat rounds however I have reverse engineered two different cartridges. The process starts with a chamber casting and slugging the bore. From there I go through my COTW book looking for likely parent cases. Next it’s off to CH4D for custom dies, then once I have a case made it’s time for measuring the case volume and running load calculations with potential powder/projectile combinations. About all this does is gives me a good educated guess on potential candidates. After that it’s time for real-world testing. Once I start zeroing in on a good candidate I have custom bullet molds cut…usually from Accurate Mold. These are for an 8mm German combo gun made in 1891 using a 9.3X72r as a parent case. That’s a 30-06 on the bottom for reference. [ATTACH type="full" alt="IMG_6600.jpeg"]427700[/ATTACH] And this is for a Holland & Holland 32 Cal 1907 Rook Rifle using a 32-20 for the parent case. Don’t have a pic of one loaded but here’s the case (right) next to a 32-20. That’s one weird shoulder. [ATTACH type="full" alt="IMG_0012.jpeg"]427701[/ATTACH] [/QUOTE]
