| So I have been reloading some pretty consistant loads for my 308. Im using 168gr. Amax, 43 gr of Varget with CCI 200 primers and the C.O.A.L at exactly 2.800". So my question is how do i find out if this is seated in the lands or just out side of them in my Remington 700? I would like to experiment with both, but im not quite sure how to measure that out. Thanks in advance! |
| Take a fired case from your rifle. Pinch the neck closed with plyers just a little. Seat bullet long. Chamber, measure many times till you get the same measurement. Eject the dummy round slowly, holding it with a finger so the ejectory does not push it into the receiver. This will give the maximum COL. |

Sounds close to me. I do that same recipe except I use 44 grain of Varget, FC cases, CCI 200 primers, 168 grain Hornady Amax and I just barely touch it with the Lee FC die. I do that because the neck tension is light on my FC cases. I get FANTASTIC shots with that! Infact I am going to load up some Nosler CC's tonight with that exact load. The only thing is the ogive on the Noslers is different so I am seating them just a tine bit deeper.
Quoted:
I did the "experiment" listed above and consistantly came up with 2.963" with my 168gr Amax's (for Remington 700) does this sound logical? If so, what would a good C.O.A.L. to start with? |

"Optimal Charge Weight" OCW 6. The seating depth for all test loads should of course be the same. I normally seat the bullet a caliber's depth into the case, or to magazine length––whichever is shorter. I don't believe loading to approach the lands is necessary, or even desirable in most situations. So long as the bullets are seated straight, with as little runout as possible, the advantages of loading close to the lands are largely over-stated. This said, be certain that the seating depth you choose does not cram the bullet into the lands. Stay at least .020" or so off the lands for these excercises.
