I have a 300 win that is 26" standard TC bbl the sammi oal shows 3.340 using freds oal gauge I show that a 150gr nosler partition green ballistic tip bullet touches my lands at a oal of3.59. This is going to be the 1st time I have hand loaded any cartridges and am just trying to get some things straight before I fill the case. How far off the lands should I be for accuracy I know about starting with the sammi but it just seems like a lot of differance between that and where my barrel is I am gonna be using IMR4350 and cci250 primers any suggestions .thanks Kurt
