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? Wanna kill these ads? We can help!
