Good day all an other question... I was trying to find out what was the max C.O.A.L for my Ruger M77mkII in 30-06 with that specific bullet, so I prepped a case and seated a bullet in long and tried in the rifle first in the mag, no problem so I pushed the dummy round in but could close the bolt so seated it a bit deeper and repeated until I could close the bolt! Then pull the round out and saw where the riffling touched the bullet so I seated other bullet an other 0.025” and measured the coal and it came in at 3.195”... so far I think I did things ok! My question is regarding loading data that says never seat a bullet deeper than the minimum OAL listed by reliable load data source! When I look up 180gr jacketed bullet the min aol is around 3.330”, so there has to be something I’m doing wrong?!?!

Maybe want to check where it was that you read that? Seating bullets so they are not touching the lands is absolutely what you want to do, for virtually any hunting type loads. If they did so, at that length, when they worked up their published loads in their rifle, then that is what they did - but used a different rifle, with different throat than yours. It also means that by seating the bullet deeper, you make the space available for the powder to be smaller, so another reason why important to read the other part in the manual about always starting at Start loads and to work up to your desired result.

Some specialist target shooters, especially with cast lead bullets, will deliberately engrave their bullets into the lands, but I do not think that is the situation that you are in?

So the info is from Lee and you are right I am not shooting lead cast bullets just hunting bonded bullets!
Thanks for the good info, I will keep doing what I did!
 
Yep, just to be clear - for hunting - have to make sure the load fits into the magazine, first. Then want to be sure it is not tight into the lands, second. If it works out that your rifle wants a shorter length than your manual used, doubly important to back off to Start load and work up - seating the bullet deeper than they did, will cause the powder to create more pressure - usually - so can not - usually - just seat deeper and continue to use their max loading...
