Grendel vs 308

[NugginFutz]

Weeeelllllll..... If you go onto the Ballistics calculator on Applied ballistic web site, it is .236 G7 and .462 G1.


When I run that BC it changes the muzzle velocity down to 2450

Good dig, bigbear. I saw that the Amax is not there, but the smell test says it should be very close to the SST and perhaps a tad better. Now, where did I put my calibrated tad-o-meter?

Can you print and post that chart? I don't know all of the in's and out's of setting those charts up but really want to see it. Anyone can change the perameters to make anything look better and this one has been bugging me. I would like to see apples to apples, not one using a factory 123gr bullets (Grendel) and the 308 getting an advantage with light weight bullet, it should be average 168gr. I shot my buddies AR-10 308 the other day and my sholder was not use to that and it was a light 147 gr PMC factory ammo. It was very accurate but shure made me want to go back to the Grendel in a hurry. Shoulder felt it for a few hour...

Ted, I'm not sure what chart you're talking about? I posted a bunch. Mine were 175 vs 123. No one felt I was comparing apples to apples and since my Grendel data wasn't 100% trued, it really wasn't. I was running a higher bc for the Grendel.

I just got the newest book. Taking the 2500-3000 fps number off of the top, the average comes out to .230 for the SST. I haven't been able to go to the range to test it yet.

The only problem I see is my velocity was 2528 averaged across 20 rounds the day I was playing with all of this. But when I enter all of the info into the calculator and try to make the poi match at different distances to what I tested in the field, the calculator changes my velocity to 2466.

That's funny, out of my 20 " Lilja, factory 123grn SST ammo is chronied at an average of 2466 fps!
