Range Report 7mm 180 ELDM blow ups.

#53
Just ordered one box of bergers to try and then if not I'll try the rdf. I figured I would try the 180 Hornet days since they were free I didn't expect that many blow ups they are junk I already emailed Hornady I want to see what they say

Loaded some 180 eldm's, oal 2.96 .that should put them about. 20 thousandths off got to 62.0 grains of h-1000 .I didn't hear or feel any crunching seating them but definitely could tell I couldn't get anymore in them .I can even hear powder move around in case. Anyone else see the same pattern

I could get about the same amount of H1000and 7977 in my ADG brass before the crunching started at mag length, 62.5 was an acceptable amount of crunch.
Thankfully R26 seems more dense and gets me plenty of speed without difficulties.

I may load up the rest of my ELDM’s with H1000 at my initial start load while shot excellent as a leisurely 2800 without them blowing.

Took the saum out today and test some more 180 's .
Used 4350 this time and the speed was quite a bit different from h1000.
Loaded from 56-58 grains, 56 grains had a velocity of 2770
58 had a velocity of 2915.
Looks like there is a node at 2830 and 2880
Try more next weekend
No blow ups

I max out at 62 grains with h1000 with a velocity of 2660 only a 24 " barrel. Throated long for a long action?

I was mid 64’s with H1000 loaded long and 180’s
I was at about 400 rounds I think when the eldm’s started blowing.
I’m well over a 1000 now and none of the other bullets are goin poof.

Took the 7 saum out today. Had some 180'sloaded up to 2900 velocity. Shot about 15 rounds in 10 minutes then I had 2 in a row blow up .was shooting at 800 they seemed to blow at about 700 yards

Ran 50 at 2880. 1-9 twist barrel. Ran them hotter than I should have, as barrel was very hot at the end. Did not see any blowups. But there is a possible massive bc reduction in the 1-9

I haven’t been keeping a spread sheet or anything, but it seems the blow ups are limited to a specific lot or lots, combined with a specific number of grooves in the barrel. 5R rifling seems to report the least blow ups. 3 and 4 groove seem to be the clear leader in the department.

Here’s a video I took I think two weeks ago.
180 ELDM’s at slightly reduced charge to get 2890 FPS
These were my first shots with that rifle that day so Absolutely cold Barrel.

On the third shot you can hear the sonic crack of the bullet stop really early.



Hopefully they straighten it out like the 147’s seem to have done.

The reticle in that video looks a lot like the reticle in my old favorite Sightron SIII.

Not trying to hijack. Had my first 338 285 ELD blow up today w a warm barrel. Going to shoot up the remaining and use Berger's. Should have learned my lesson w the 147 ELD.

Well on a side note I also shot my 300 Win Mag today at 1900 yards and I have three shots never had a splash I can't say 100% that I was having blow ups but my buddy was right next to me shooting his song and we could never see a splash and we moved closer and we realized with the sound he was having blowouts

That’s a bit surprising and disheartening.
I really like the 285.
I had problems with the 147’s and 180’s.
I’m thinking it’s a batch problem as much as anything else because suddenly on getting a new supply I started having issues.
I’m shooting the rest of my 140’s quite fast and they’re doing ok still.
