Here is a new one on me and I have zero idea how to proceed. I shoot and reload for my 6.5CM with Hornady brass. A coworker bought a few bags of Starline SRP at a garage sale over the weekend and sold them to me for a song . Here is my dilemma , all of my data is based on Hornady brass and large rifle primers. Do I drop the charge weight a grain or more and move on or start a new work up? All my previous data is mid line and below max , but I have never used the 6.5CM SRP brass. Thoughts and advice would be most appreciated.
