How come the Hornady 8th edition manual shows 12.9 gr of Bluedot as a max load for the 155 gr XTP and the Nosler manual shows a max load of 11.2 gr for their 150 gr bullet? That seems like quite a spread. This weekend I shot a bunch of the 150 gr Noslers loaded at 11.2 and they shot good but seemed a little light. I recently purchased a 22lb Wolff spring so I popped it in to try it. Would not eject the brass. Loaded some 165 gr Underwood ammo I had and they flew 10 feet away. I'm shooting a 6.6 threaded LW barrel with their comp. It would probably cycle if I removed the comp but didn't try that, just put the stock spring back in. Bottom line, can I use 155 XTP Hornady manual as my guide with the 150 Noslers? Would 12.9 gr of Bluedot behind the Nosler 150 be safe? Why does Nosler data seem so weak?
