[QUOTE="MagnumManiac, post: 1162738, member: 10755"] With bullets that have a tangent ogive, I have had my best results either just touching lightly, or .010"-.020" away from the LANDS in my 300WM, 020" being, on average, the best compromise. My load workup is less precise than many here, I load 5 rounds starting 5% lower than max listed, all at .010" from the lands. I shoot my groups @ 200yrds then choose the tighest group out of those, load above and below that charge in .3gr increments for 3 above and 3 below. If groups tighten, I pick the best load, then I load 5 with the bullet touching and 5 @.020" away and choose whichever is the tighest. I will say, that my comp rifle barrels in 300WM are less effected to seating variation than my long range hunting rig, it is very finnicky. I used to do a ladder test, but found the components used working out seating depth was about the same as above, anyway. Cheers. gun) [/QUOTE]
