I just thought N135 would be less temp sensitive than this. I did make a note that my dope changed at 300 today vs 78°. 78° had 1.9 MRAD and today I had to dial up to 2.1 to get the same impact. Maybe a combination of lower temp and the break combined? Either way, I'll change back to the A2 and run some M855 through it. If it's my loads on the weaker side, I'm kinda bummed. This lighter load produced the best group and best SD all the way up to 2600 FPS.</blockquote>
