I load to the length that reliably clears the mag; then check to make sure the bullet is not engaging the rifling. The issue is powder capacity. I would prefer a slower powder than 4198, such as H335 or 3031.
One thing that helps a lot is using a round nose bullet. They are shorter than the pointed ones.

WhelanLad - I just received the 2014 Woodleigh reloading manual - they describe how to establish maximum COAL in your rifle - using wood dowels or a dowel with a cleaning rod. Then they recommend .020" to .040" "clearance" or "jump" for starting - some bullets / rifles might want more or less jump. As per the post #3 above, for a hunter, whatever number you come up with MUST fit and feed from the magazine - FIRST. Once that is established, likely want to know that you are not "jamming" into your lands, at that length.
Despite what you might read on-line - is not necessary to spend $$$ to buy gizmo for establishing that length. Some fuss a lot about variation among bullet tip to ogive in a box of bullets - but then fire the things in a mass produced, store-bought rifle. Not sure that will amount to any difference that you could see on your target - whether measuring from bullet ogive or from bullet tip - if you already "backed off" .020" or so. I had previously read the same procedure - possibly in a Nosler manual, possibly in a John Barsness book or article - has been my practice for many years - fit the bullet length to feed from magazine, then ensure that the bullet is not "jammed" into the lands - and then go shoot stuff.
I do load with mostly "standard" bullet seaters - so the seating "cup" is going to contact the bullet somewhere - not necessarily on the bullet ogive - but seems once set - all the loads are going to be the same - from the cartridge face / headstamp to the bullet seater contact point. Is possible to measure some variation from rear of case head to some bullet tips - and that might make difference for bench rest competition and or custom made barrels - not sure, though, it has ever caused me to "miss" a deer that I shot at.

cheers, 2.245 or there abouts is working fine, id normally do what potash is gettin at in regards to flipping a projectile in a case n jamming it in, but im finding the LEE sizer is sizing it enough to comfortably hold .308 130ppsn projectiles???? an once fired, the .311 is so loose it doesnt work.
at the time of post i did not have or was not in position to do either checking or confirming- but quickly worked it out an continued on shooting
4198 i like its character- it is quick, but it doesnt Slam, Push or act wild- i use in few other guns and figure it is doing a real good job around 2000fps that changin to another powder isnt worth the money- an the fps is not there to worry about.
all in all. very very happy 4198 150gr 762x39
