28 Nosler 180 ELDM VS 195 EOL

[TX Badger]

Why would the 195 take over if it has a lower BC?

IF it has a lower BC. I would want to see this level of detail before I was convinced. Maybe? Maybe not?

Are you using .391 G7 bc for your on paper comparison for the 180? If you are, it is an incorrect/biased comparison, you will want to use .378 if you want a more realistic apples to apples comparison.....Berger averages their bc down to 1500 fps, and .378 is the averaged bc of the 180 eldm's listed bc's at 2512 fps (.391), 2232 fps (.376), and 1953 fps (.368). When you look at Berger, the 195 EOL velocity/G7 bc's are .385 above 3000, .385 from 3000-2500, .382 from 2500-2000, .389 from 2000-1500, and .398 below 1500. The average useable hunting velocity (above 1500 for reliable expansion) is .387, however the updated Applied Ballistic app gives a G7 bc of .380 on the bullet profile on the 195 for whatever reason.

Also, and I may be incorrect, but I doubt you will get 200 fps faster with a bullet that is only 15 grains lighter and I believe has a longer bearing surface. Even so, if you run with the bc's I listed for a more fair comparison, and compare the 195@3050 and 180 at a more attainable 3150 fps, the ELD-M comes out with a slight advantage in wind drift and drop out to 1500 yards, but in wind drift we're talking a difference of 0.1 MOA at 1000-1500 yards, and less than that in closer. The 195 has more energy, but not enough to be significant.

If it were me, I would shoot both the 195 and 180, see what velocity I can get them to, but ultimately go with whichever one is more accurate and consistent, because that will make more of a difference at range than the performance difference between the two, that's how close they are.

I used 4dof for my solution 3230 for the 180 and 3150 for the 195. The energy at 1500 is 1005ft/# for the 180 and 923Ft/# for the 195. Shooting to 703 Sunday my drops at 303 507 and 703 were all 1/4-1/2 moa high for the 147 @2920 out of my creed. Mine issue was my scope height was not correct. After running the program with the right number gaining 1-2 clicks for the same distances. If I could read wind abit better would have helped also. I held 4 shots with less than 1 inch of vertical@703 in roughly 4x1" The 300yd distance seems to be super easy with my load.a cloverleaf with 1 above 2 the bottom 2 touching and the top had broke the paper between those 2 but not exactly touching.
We shot my creed and 2 7mags with the 162 eldm and it was really on the money using their library @ 21' above sea level via gps altimiter

In my 28 Nosler the 180 ELD running 3250 shoots good until the third round which is when the barrel heats up and they don't get to the target in one piece. I run the 197's now but at 3070.

Venatic what powder were you using with the 180 and now with the 197's? Barrel specs?
