Newbie question here, if you'd be so kind as to enlighten me.......

I'm loading .308 using Hornady 150 gr. FMJBT in Winchester brass using H-Varget powder (43-45 gr. charges) and Remington # 9 1/2 large rifle primers. The load data from a number of sources consistently indicates an O.A.L. of 2.8", but when I seat the bullet the crimp groove is well above the case mouth. If I set the seating die so that the crimp groove is halfway in/out of the case mouth I end up with an O.A.L. of 2.720". I'm using Lee dies (with the factory crimp die). Should I adhere to the 2.8" data, or seat it at the halfway mark of the bullet's crimp groove? BTW - the factory Winchester .308 168gr FMJ HP ammo I have on-hand measures out at 2.706" on the caliper.

Any input would be greatly appreciated.
