I'm not convinced that seating bullets near the lands does anything good for accuracy. I've played with it a bit in the past and found that its more of a waste of good bullets and gunpowder than its worth. I Use a OAL guage to figure out what my max length is so I don't mistakenly seat bullets any closer than 0.020" to the lands, I prefer farther away if possible with jacketed bulelts.
Well, I never posted this to find the most accurate or whatever. I have been successful on doing that with quite an array of rifles as you probably have also. I rarely find a rifle with such a short throat to even worry about this. I posted this cause I am without my stoney until my buddy sends it back, and I was wanting experience with people who use the Split case method. Because the throat is so short.
And its no secret to any reloader that jamming in the rifling can cause you to show pressure signs way before reaching the velocity potential.
