UNCLEBILL, You are seeing details that half here are missing. You are shooting a single shot contender/encore type rifle. there is a huge difference in chamber operating pressures between a single shot and an AR platform. Do not use the suggestions given for AR load data in your contender. Too hot a load for it. The AR platforms tap some of the chamber pressure to operate the gas system for feeding and ejection. some gas goes out the muzzle, some goes out thru the upper receiver. With the contender it all goes out the muzzle. stick to what works for "YOUR RIFLE".
