Re: Seating into the lands or not
muleyman, here's the trouble with seating bullets in contact with the lands, as I see it. You must be very careful with your method of measurement and you must make sure the bullets are not seated too long from run to run. Seating bullets in contact with the lands and Measuring COL from the bullet tip is a disaster waiting to happen.
You really need a comparator and OAL gage for repeatable results.
Besides that, if you are at or near max pressures with your load, and something changes (ie, temperature, seating depth, altitude, small powder variations, primer lot, case capacity, etc) then you run a risk of excessive pressure! Not fun.
You will find yourself safer in general by seating bullets .020-.040 off the lands (Stoney point OAL gage recommendation). Somewhere in there, you'll find a sweet spot your rifle likes best.
If in doubt, the safest practice is to simply seat bullets to spec COL and call it a day.
