.308 Ammo reloading question OAL

I had horrible results using hornady Match 168gr hollowpoints yet Federal Match,Wilchester Supreme Silvertip, Federal american eagles and DAG surplus run great groups... I think I know why the hornady OAL is about 2.718 and the others are around 2.746 to2.760...

Now using the slit brass and bullet trick "cut slits in the neck of a case , put a bullet in it, close/cycle the bolt about ten times measure the results each time, you should not + or - more than 0.002 if you have proper tension on bullet" I found my bullet hit's the lands on my Savage 10 at 2.810 and the closer to lands you get the better the accuracy "duh"... But my question is when reloading How far from the lands should I be with OAL if 2.810 touches would reducing by .002, .005 or .010 be best ? or should I just load till it hits lands "2.810" but don't know if that'd be wise as the bullet might get jammed in there making unloading a chambered round a problem such as pulling the case from the bullet spilling powder everywhere and having a stuck bullet in barrel.

crap put in wrong forum, hopefully a mod will move it to reloading section for me and not delete it and send me a "we don't like yer' kind around heyar" type message

Seating depth preference varies by rifle. If you seat your bullets into the lands you will not have any stuck bullet problems. A properly sized case holds the bullet tightly so extraction is not a problem. I know reloaders who load .007 to .010 into the lands for accuracy. You have to be carefull with your powder charge if you do that. You have to work up slow and weigh each charge. I would try .030 out of the lands and work closer in .010 increments until you are at the lands using a beginning charge to see where your rifle's sweet spot is. Also neck sizing helps.

what you want to do is get the hornady oal guage and bullet comparator and some good calipers. Then you can measure using the ogive of the bullet instead of the tip. The ogive is what really matters and will help your rounds be as accurate as possible.
