distance off lands

How far do you load off of the lands and why? I used the carbon black (candle) method to find col 3.211 to the lands with the accubond 110gr in my 25-06. Nosler loads this combo to col 3.125. To me that seams a big difference. What do you think?

I would like to be able to "load of the lands" but my Ruger 77-II 300 WM has a magazine that restricts the COL. I always measure using a StoneyPoint guage and check it against my magazine length. The magazine always wins. I envy those that can put their bullet near the lands.

You have to let the gun tell you what it likes.I start at .015" off the lands and experiment to see where the accuracy is best.I have rifles that shoot best with the bullet seated very close to the lands,and others that like a little more bullet jump to the lands.

Same exact thing stubble says. If you want optimal velocity, then you need to give the bullet some room. I never could figure out why the manuals pushed all this stuff so hard. It tripped me up when I started reloading. I found out, its sometimes best to even go deeper. My main concern is good reliable, easily feedable ammo that shoots a good consistent 1MOA. Clover leafs are great but under 600 yards won't mean much.

Unless you have a match grade barrel with the bolt face squared to it, and the entire action squared and trued, you usually aren't going to get benifits from loading to the lands. I do what the previous posters do, but I start 0.020" back. If the rifle has a long throat, I seat the bullets 1 diameter back to get consistant neck tension.

Same here. .015" - .020" off the lands, magazine length permitting. Barnes suggest loading their TSX bullets .050" off the lands as a starting point.

Im usually about .02 off the lands also. My chamber in my browning 30-06 is only about 1/100th from where the stated COL in the manual is. Boy, they cut em close. The mag in the browning just barely clears with the bullet .015. Its perfect!

Same here. If you want perfection (and you'll never get it) you have to find what your gun likes. Bullet choice has a big impact onthroat clearance also. I don't have a set distance for each chamber, but work with each bullet/powder/ seating depth combo to find what shoots best. Watch for signs of excess chamber pressure while you're working those loads up.

ditto the .020.... The ogive of your bullet will make the jump and retain it's accurracy even further on back.
