Since I'm beginning to reload with 8208, I decided to do some checking if I should decide to single load my Grendel for more precise competition shooting. I found a few interesting (at least to me) items while doing research. I used my AA Hunter upper as the test bed.
Bullet length ~1.181"
OAL to Lands- 2.236"
Ogive to Lands- 1.736"
Bullet Length ~1.291"
OAL to Lands- 2.323"
Ogive to Lands- 1.720"
Bullet length ~1.236"
OAL to Lands- 2.282"
Ogive to Lands- 1.710"
What I took away from this-
1- The shortest bullet had the shortest OAL to the lands, but also is bluntest with a tip to ogive of .5 (120 SMK)
2- The 123 SMK is 0.055" longer than the 123 AMAX
3- The OAL to lands on the 123 SMK and the 123 AMAX is a difference of 0.041" (In favor of the 123 SMK)
4- But, the overall difference between the Ogive to lands of the 123 SMK and 123 AMAX is only 0.010" (The 123 SMK hits the lands slightly longer)
So, it will be interesting to see how they stack up when I load some rounds 0.010" off the lands and see what happens.
I am just an average guy reloading ammo and this may not mean much in the big picture, but I found it interesting. If my data conclusions are incorrect, please correct for me.
