I've run into an issue with some reloads for a friends rifle. I worked up a load of 26.4 gr of H335 under a 35gr Berger with a WSR primer. It shoots under an inch and is right in the middle of the book load min/max, but we are getting 30-40% split necks by the 2nd reload. These were super performance 40 gr factory's originally.
This is the first time I've loaded hornady brass. Is it really that bad or am I doing something wrong? I load several different small cartridges and have not seen this degree of splitting ever.
