[QUOTE="benchracer, post: 1329594, member: 22069"] This is my first experience with a wildcat cartridge of any kind, so there has already been something of a learning curve for me. Loading for the Sherman wildcats is not difficult, but it is different. I will detail what I have learned as this thread progresses. In the interest of exploring the capabilities of the 338 Sherman, I intend to do a lot of load work with this rifle. Rich Sherman designed this cartridge around 250 grain bullets, specifically, the Berger 250 Elite Hunter. I will be using Hornady 250 HPBT's to fire form my initial batch of brass, to be followed by testing with Berger 250 EH and Cutting Edge 252 MTH's. I will also be testing Cutting Edge MTH's in 225 and 200 grain weights, along with Hornady 225 and 200 SST's. I currently have 50 rounds each of PRVI and NORMA brass loaded with fire forming loads. I also plan to fire form and test RWS brass at a later time. During the planning phase for this build, Rich and I had discussed use of RL-26 with the 250's. However, the initial results with Rich's 338 were not what we had hoped for. He had much better luck with RL-17 and Hybrid 100V. After discussing the matter, it seemed likely that the disappointing initial results with RL-26 may be caused by an ignition problem. With that in mind, I will give RL-26 another go, using different brands of mag primers, in hopes of getting the results we were hoping for. Otherwise, RL-17 and Hybrid 100 V will be tested with the full spectrum of the bullets listed above. I will report back as I have results... [/QUOTE]
