I know this is a nosler forum, but i have all the books, in the barnes book #4, i am just wanting to know if anyone can tell me if the C.O.A.L. that is suggested for each different load and bullet is what they recommend for each of those bullets once the round is loaded, of if it is the minimum that you should load your round at, for instance i have a 7mm WSM and for the 140 grn bullets it has 3 of them and they are all different, tsx=2.750" mrx=2.830" and bnd spt=2.800", is that where i should have my loaded rounds at for each of those, or is that the minimum that they should be loaded at?

The Barnes Manual is informing you for the length to which they loaded their round. There are various reasons for choosing the particular length. The rule for monolithic bullets still holds: allow some jump to the lands. Barnes suggests 0.030 to 0.070 inches off the lands. In fact, their technicians have found that many rifles have a sweet spot with monolithic bullets at 0.100 and more off the lands. Your own rifle will tell you the OAL required for accuracy.

i am using the ttsx, so i have been just using the load data for the tsx, that says 2.750", and my magazine can easily handle 2.860" which is the sami max for the 7mm WSM, so are you saying just load them at around 2.860 and go for it, or should i try something like right in the middle of what they say and the max like maybe 2.800"
