I am looking for load data for a old wildcat. 22-243 Middelstead. I found it at a gunsmith deceased auction about 20 years ago. I bought it just for the large ring action but now I have a need for a fast 22 that will shoot a heavy bullet to buck high winds. The cases fireformed great with half a case of 380 and light bullets. Since then every load I have tried blowes out the primers. I have tried reduced loads for 22-250 and 220 swift as starting points with no succes with 70 gr Speer
