[QUOTE="timberelk, post: 1400124, member: 100952"] After much research and reading I decided to attempt to locate my lands... I took once fired brass, inserted a new 140 grain Nosler BT, removed my firing pin from the bolt and chambered the dummy round. I did it several times and each time I was with .001-.003 when using the Hornady bullet comparator so I believe my method worked. This resulted in a COAL of 2.903”. The Nosler book says the COAL they used was 2.880”. I was thinking about setting the bullet off the lands about .020” which results in a COAL of 2.883” So I’m .080” longer than the Nosler loading book... is that too long? Does it not matter as long as it works in my gun? This will be hunting ammo so should I back the bullet off the lands by more than .020”? Maybe .030”? Or .040”? Thanks for helping a newbie! [/QUOTE]
