I just started loading for the 308. I have some Varget and wanted to try a few loads with it. In consulting the Lyman and Lee manuals I decided to start at 44 grains. I am also using 150 grain Hornady FMJ with cannalure. The OAL is suppose to be 2.800". My question to you all is that when I do this, the cannalure is still quite exposed and I cannot crimp into it. Am I doing something wrong? Should I seat the bullet deeper?
 
What kind of rifle? If it's bolt action, you need not crimp. My understanding is that a semi-auto or lever action requires a crimp.
The OAL will depend on the bullet and how far a jump or jam you want.

Nope. You don't need to crimp.

Regarding overall length, I load so that the bullets are quite close to the rifling, often over the nominal normal length of 2.8". If for field use the mag length may limit overall length. If single loading from the bench it doesn't matter how long it is.
 
If you are loading FMJ just load to the cannelure. Assuming these are FMJ intended for 7.62 NATO/ .308 Win and not old M2 .30-06 bullets.

Seating just off the lands etc etc won't really matter with a bullet of this quality level.
