Range Report 178 ELD Match BC . . . what are you using/getting?

[z7.jled]

I have been doing some good work with the 178 ELD Match out of the 308 and have settled on 44g of Varget winchester brass. It shoots way better then me. I recently purchased TRASOL after reading about it and was looking over my notes and wanted to see how TRASOL matched up with my real world experience

About two months ago I was shooting at 600 and 1000 yds at steel plates and the drop data I had from the hornady 4dof was spot on. 10mils at 1000 and 4.1mils at 600. my inputs to hornady 4DOF calculator were for 2700fps (assumed) with the forecasted weather. it was about 80 degree and dry that day.

I put the same info info into today TRASOL and using the published BC of .275 (G7) and I end up with 9.7 mils. BUT my DA according to TRASOL is about 2200ft. I have no idea what my DA was two months ago.

just wondering what BC any of you may have found with the hornady 178ELD Match flying out of the muzzle around 2700fps

Also, for TRASOL, is the act of "truing" just a matter of tweaking BC and MV of the bullet to match real experience? how close is "good enough" for the BC? .1mil? .2 mil? I need a chronograph, i know


if it helps,
24" barrel, 1-10" twist
44g of Varget
Winchester brass

That sounds like a great load. What is your coal? How far are you from the rifling? What primer are you using?

FWIW, that is the exact load that I use with 175 gr SMK.

I am just touching the lands, 2.830"coal, CCI br2. I put 4 shots of a 5 shot group into a .2" group, shot 5 I screwed up trigger control and threw it 1/2" high,

For me the 178 ELD-X have been Very accurate. The M was not available when I bought 800. The X has given me groups from 1/2 to 1/3 moa in my AI-AE 1-12 26in barrel. At range I have shoot them out to 1400 yards and when wind is down the do very good.

Brass Lapua
Primer CCI BR2
Powder Varget = 42.9
AVG FPS 2721
COAL 2.88


I load them 20 off the lands.

I'm with GIXXER2000 on this. The 178 ELD-X have been very accurate for me as well. They stay supersonic just past 1200 yd out of my Remington 24" R5 Milspec. No need to bother with the M's IMHO. My load is 43.3 gr of Varget @ 2.805 OAL. Muzzle velocity is 2650. They did not like to be loaded long in my gun for what its worth.

I actually get the advertised bc with the 178 eld. With your TRASOL, do you verify your DA with kestrel or something? I dont use the automatic DA on trasol...as a matter of fact Im not super impressed with TRASOL really, works the same as all the other apps. I had to tweak the BC and muzzle velocity and the drag coeffieinet to align the data, on ballistic ae, I used the truing tool, and then brought down the BC to match everything up. Its just so the computer can relate it to your dope, it has no real reflection on the actual bc of the bullet. Wright down true dope is always the way to go, but keep better notes, wright down DA and light conditions and wind conditions before you start walking rounds on target and putting in numbers on your paper. Take that paper and play with those numbers on your software till they match up. Then go verify again.

So far with trasol it has matched my dope out to 1000yds. granted, this is one location with very similar weather each day (Tampa, FL in spring, hot, humid, little wind).

I have not checked DA against anything. I did go online to a DA calculator (not sure where I found it) and entered the variables from the weather channel and TRASOL was within 100ft.

Yeah just tweak...the bc is pretty accurate. the numbers just dont match up to the calculator.
