Guys -
I wanted to shoot 140gr Berger VLD in a <span style="font-weight: bold">6.5 Creedmoor</span> DPMS profile <span style="font-weight: bold">semi auto gun.</span>
I spent all day on this and I am stunned at the results:
Took a brand new Hornady case and sized it with an RCBS small base full length die.
Then I drilled out the flash hole and cut 2 slits opposite of eachother on the case neck down to the shoulder.
I placed a bullet in the case and slid it deep to make contact with a wooden dowl pushed through the bottom of the case to contact the bottom of the bullet.
I placed the dummy cartridge into the chamber and fully seated the brass first.
I then lightly tapped the wooden dowl until the bullet stopped moving forward - seating the bullet OGIVE in to the lands (jammed into the lands).
At this point I marked where the base of the case rim was even with the dowel.
Using a rod I popped out the cartridge.
Reassembled the bullet into the case and dowl through the bottom to the line I marked above.
Measured from the base of the case to the tip of the bullet for C.O.A.L
<span style="font-weight: bold">2.970</span>
<span style="color: #CC0000"><span style="font-weight: bold">So employing the data below I don't see how I will be able to fit any of the bullets into a PMAG or standard DPMS mag.</span></span>
Load 24 rounds at the following COAL if you are a hunter (pulling a bullet out of the case with your rifling while in the field can be a hunt ending event which must be avoided) or a competition shooter who worries about pulling a bullet during a match:
.010 off the lands (jump) 6 rounds Which would be 2.960
.050 off the lands (jump) 6 rounds Would be 2.920
.090 off the lands (jump) 6 rounds Would sit at 2.880
.130 off the lands (jump) 6 rounds I could maybe squeeze in at 2.840
The barrel is a 20" Criterion with a 6.5 Creedmoor chamber, bought from Fulton-Armory.
Is my method sound?
Those of you shooting VLDs in a gas gun, did you come up with the same COAL measurements?
Thanks in advance -
BB
