![]() ![]() It too is based on the 6.8 SPC case, but here the case has been necked up to. It was also intended to work with subsonic and supersonic loads. 458 SOCOM, this cartridge was intended to offer broad spectrum application, but was primarily designed to deliver heavy, high-ballistic-coefficient bullets, at extended distance. 338 Spectre wildcat cartridge Richard Mannĭeveloped by Marty Ter Weeme, founder of Teppo Jutsu L.L.C., who also developed the. 22 “Prairie Dog Killer” inspired today’s 22 Nosler. 32 H&R Magnum cases lying around, or are bored beyond belief, this cartridge is a waste of time. Pushing a 20-grain bullet to about 3300 fps, ballistically it falls between the. 17-caliber and chamber a Ruger #3 single-shot rifle to fire them. He decided to neck the pistol cartridge cases down to. Pilant says it came to him in the middle of the night, but he’s not sure whether it was a dream or a nightmare. 17-32 Magnum came about because Pilant was trying to figure out what to do with more than 1,000 empty. Unlike most wildcats, which are conceived to solve some shooter’s ballistic conundrum, the. Richard MannĪvid shooter and long-time Sierra Bullets employee Carroll Pilant created this cartridge. 17-32 Magnum to use up a bunch of leftover cartridge cases. And while there’s really nothing wrong with any of them-no one really wanted them either. They didn’t take off because, well, they’re a little weird. Here are five wildcats you’ve probably never heard of, and probably never will again. This is mostly because the only person who cared about the ballistic need they addressed was the person who created them. But most wildcat cartridges never achieve any popularity. They were all created to address certain ballistic needs, and some were so successful that they ultimately became approved by the Sporting Arms and Ammunition Manufacture’s Association (SAAMI) and went on to become legends. There are a lot of famous wildcat cartridges, like as the. Slap either the creedmoor or Blackout name on it and call it a multipurpose round and it will probably sell.We may earn revenue from the products available on this page and participate in affiliate programs. I hope out of the gate they focus on good subsonic expansion with heavy bullets, maybe that will help drive better expanding low velocity bullets in several different bore sizes. I bet this is a fun project for whoever is working on it large frame AR/short action DBM mag length restrictions for OAL, low case capacity for typical bullet weights in that bore, long but slow bullets to stabilize at two different velocity thresholds, most customers probably won’t want a barrel much longer than 20”, that’s a lot of compromises to fit into one package. any supersonic advantage gained from higher SAAMI pressure will be reduced a bit from a smaller case capacity, The shorter shoulder length would help a bit with seating longer bullets at mag length which will help on both the sub and super end of the spectrum. 030 to keep bolts from chambering on a 6.5 creedmoor in an 8.6 chamber meaning even less capacity. 338 Fed/.358 win cases but the creedmoor case already has less capacity and they will probably do something legally well advised like push the shoulder back. I can see some of the argument for using a creedmoor case from being able to run at slightly higher pressures than the. Maybe some companies will make some 338 bullets better suited for this cartridge? The 230 ELD-X seems like the best to me but if I'm missing something I'd love to hear it. I'd love a 12.5" large frame that is as versatile as this cartridge seems. Very curious how fast the 230's will be pushed with this cartridge. Would love to hear more thoughts / comparisons. Heavy subs for <100 yds and supersonic capability to 200-250 yds.įor comparison, I used the 6.5 Grendel shooting a 130gr Berger at 2400 fps. The 375 Raptor seems much more like the AR10 version of the 300blk. ![]() It can obviously shoot heavy subs as well. This comparison only gets better if the 8.6 can shoot the 230's faster. Both these cartridges are within 0.5 mil to 750 yds. The only downside is obviously trajectory (13.4 mils to 1k vs. JBM says the 230 ELD-X stays supersonic to just over 1,000 at 2k elevation with a MV of 2,200 fps. To me, it almost seems like the 6.5G big brother if it can push the 230 ELD-X at a decent speed. ![]()
