[QUOTE="thor447, post: 3313342, member: 24867"] Quick question for you all regarding load data C.O.A.L vs. actual rifle C.O.A.L Ok, my load data from Sierra says that my total cartridge length should be 2.810" [ATTACH=full]150639[/ATTACH] I found the measurement from my closed bolt face to my lands using Oklahomabassin's method he posted earlier, as well as a second method I found online - starting at 2:07 [MEDIA=youtube]9OZ8u8e7mSc[/MEDIA]) I made my own tool instead of buying the one shown in the video. Both methods got me exactly the same measurement, and I was able to calculate my rifles max C.O.A.L with the SMK 150gr bullet at the lands at 2.2975". When the time comes (after breaking in the new rifle) I can make some rounds at this length, as well as 0.010" and 0.020" short of the lands for testing, etc. My question is that my rifle's actual C.O.A.L is quite a bit longer than the load data's value. Should I stick with the load data, or is it safe, if not advisable, to load to my rifle's actual measurement? Obviously loading to the longer C.O.A.L will change the amount of empty space inside the round, and I'm not sure how that would affect it. Knowing the distance of the bolt to the lands in my rifle (which is 2.225"), will help me when loading different projectiles in the future. Any advise would be appreciated. Thanks. And down the rabbit hole I go.... [/QUOTE]
