OK that all didn't come out. Anyway the old guy had a wildcat based on the 284 Winchester case. Cut off the shoulder sized it and was loading 45acp 230 grain round nosed bullets. Basic firearm was a Ar 15 with heavy barrel and muzzle break. He cut the carry handle off and installed a Weaver picatinny rail and has a scope mounted. Always thought the 230 grain RN was a poor choice for a bullet. the gun was literally drenched in oil. 250 grain would have been better. Can anyone remember what they called that cartridge??. Thanks,Frank
