Sitting at range with first 3 shots of 162gn eldm ladder test. 60 and 60.2gn same hole on left then 60.4gn to right. Parking ladder test (up to 61.4gn) to repeat a group at 60.2gn.

Hi Tikka7mm08,
What's the app you're using to measure your groupings?
How does the labradar go?
Cheers

App is Range Buddy. Labradar goes great top kit.
Just go and shoot a deer
Soon. Want to get the stock cerakoted first.
@Tikka7mm08 have you decided which load you're gunna run with....both look good.
Oh...and go shoot something before you need a new barrel:P
Not sure yet. Yes....will do. Gotta pick up the Montana 308 and test that next.
Mate, you’ve got more patience than me. I’d have deep sixed the bloody thing by now!��
0.5 and 3/4MOA groups shows patience pays off...to be fair I should have got it bedded much sooner.
Did Nathan bed this one ? I have just ordered two of his full length bedding kits, only fourty something bucks per rifle
No Zach did it. Also done the Montana 308 as I figured might as well even though I was happy with how it was shooting. Can't wait to try the 308.
Group shot this evening. 180gn ELDM with 58.6gn RE26, CCI LRM primer, Norma brass. COAL 3.380" per @burtonator.

Lovely.
Been a hard road.
Watching with interest
180eldms at over 2800fps is going to be devastating
Drop table with 180gn ELDM @ 2850fps 100y zero. Note BC used is 0.796. This BC is from the hornady website. I'll be able to try real world test on 600y gong at home.
Absolute hammer.

That down range energy is impressive
Yep it thumps the 162gn on energy but the 180gn isn't flatter shooting until 1000y. Still, very little given away by the 180.
What a relief to finally get a load sorted aye mate, and mag fed

Yeah, watch out for Internet sourced advice.
COAL adjusted to 3.340" for mag fit. Unlike 3.380", which is not mag fit. FFS.
58.4gn (0.5 MOA first shot cold clean barrel to left) and 58.8gn shot well. Going to try 59.0gn to see if group comes in or holds nearer to 2850fps. Only 12-13deg today.

59gn did much the same as 58.8gn. Interesting the 40 thou shorter COAL has (I think although small sample size) reduced pressure as speed has dropped from 2850fps. No pressure and I feel there is another node above 59gn but going to now settle at 58.4gn and 0.5 MOA a little over 2800 fps.
Anyone able to confirm the BC of the 180 eldm? Seen two Hornady sources quote .777 and .796.

LOL ... Anyone able to confirm the BC of the 180 eldm? Seen two Hornady sources quote .777 and .796.
Glad to see its not just me.
Hornady like to make it as confusing as possible with BCs for different twist rates and different velocities.
I've seen G1 numbers quoted from 0.810, 0.796 (original hornady claim) to 0.703 (Litz).
I've come up with my "own" BC based on twist, muzzle velocity and range out to 1000 yrds for my N28 = 0.756.
As stated on the box by Hornady ...
180ELDMs >2500 fps 0.777
2230 - 2500 fps 0.748
1500 - 2200 fps 0.731
Have verified this on gongs at 625 yards but you'd probably want to stretch further out to really verify the number.
Yeah bit confusing, they have Mac 1 and Mach 2 but I think Strelok does all the calcs if you plug in the nominal BC? I'll test out to 600y and see where I get to.
Mach 1. I'm hungry.
I'm not sure of exact BC but I've been using. 796 recently. Shot out to 350 and found it was reasonably close.

For those interested, I've also just done a load for a kimber 280ai using 58.8grns RL 26, 180eldm, Norma brass, federal 215 magnum primers, coal 3.340 to fit mag and it shoots well sub MOA.
Attachment 189723
Final sight in today for 100 yard zero. And then 600 yard drop table test in pic (ignore bullseye shot that was @Stag at 400y) just before rain hit.
Seems be shooting a little low. I had the bc at .777 and the speed at 2813.

That’s a tight wee group.
Have you tried adjusting the BC so it correlates with the 6.8inch drop? Jury seem to be out on the BC of those pills.
Scratching my head to honest. Could be my shooting. Played with BC and speed but seems quite a gap. Scope dials spot on.
I guess that’s the purpose o validation. Create your own validated drop chart……certainly looks like it shoots well, ideally a third shot would give you that confidence.Quote:

Good shooting. Re your other thread question kimber / Rem mags, I compared the Rem 700 follower and the Kimber. The Rem is longer by prob 6mm. The Rem is a double stack and the Kimber a single, so the two are not at all compatible for a swap. The kimber follower has an abrupt step in the follower at the shoulder area of the case which would be fine with a 280 but is more than likely too abrupt for an AI with it's 40 degree shoulder. Do rounds lift up too much at the front when being loaded, is this the problem ? cant do much about mag length
All good. I read the follower and spring can be a weak point on them.
If the scope does 1 inch rather than 1 moa there's about 3 inches of missing vertical?Quote:

Sometimes also you are just chasing your tail for fun:D
I should have measured with a ruler so not sure exactly. Scope 1/4 MOA.Quote:

SMOA on Strelok lifts it a few inches. Doesn't have that setting for the table which is a bugger so left with MOA on that.
