[QUOTE="cstilt, post: 535077, member: 19720"] I don't have a perfect answer for all your questions, so I can only state what I know. When I switched between different 150gr factory loads in my rifle, the BOSS setting would sometimes be very different. I'd imagine that changing anything in the load could have a large change on the accuracy. Rifles all suffer from the butterfly effect. Change one tiny thing and it can have a completely different outcome. I will tell you that my 270win is slower than it should be. I'm currently getting 2850 from 59gr of H4831 when it should be 2900s. This is because of the BOSS and false advertising. They say my rifle has a 22" barrel. That's 22" including the BOSS, just the barrel its self is 20". I'm betting yours is a bit slower than it should for the same reason. Measure it with a cleaning rod with the BOSS off and I'll bet you're 2" short of what you were thinking, I sure was. This past weekend I finally gutted the plastic bedding in mine and replaced it with Devcon. I've not shot it yet though. My thinking was plastic like things can become harder or softer if different temps, so that stuff might too. Didn't like the idea mushy stuff behind the recoil lug either. We'll find out if I did the right thing when I'm able to go to the range. On a side note, look into the Timney trigger springs on midway. I replaced mine with the 2lb spring and it feels so much better. [/QUOTE]
