I have some left (350 or so), but can't find them anywhere to save my lifeThe oldschool 142 smk is a great bullet with a tough jacket.
If you are having issues with hornady 147s coming apart in flight.......you may get the same result with hornady 140s (not sure if jacket thickness/toughness is the same.)
The 140 HPBT is a solid budget choice, and no not the same jacket.If you want to switch bullets, what are good options for a 6.5CM?
I realize Berger would be the best, but availability is still a huge issue.
Are Hornady 140 HPBT an option?
Nosler 140 CC or RDX
Barnes 140 Match Burners
Are there any Sierra options?
Use Case: Regularly shooting to 1200 out a SS Proof Research barrel.

I did manage to find 200 140 ELDMs at Scheels (too bad I can't pick them up, but it is free shipping).The Hornady 140 BTHP aren't a bad bullet but BC is a good deal lower than the newer 140 bullets. Much better than the 140 SMK which is a terrible BC for a 6.5 bullet.

The Hornady 140 BTHP is a worst case scenario. I would ideally like to go with a newer bullet.
These were 5 shot groups at 350m loaded with 147 eldms I shot this last spring during load development. They would shoot .5 moa groups at 100m and then blow up or destabilize between 300-400m.I know this is a somewhat older thread, but are people still seeing these 147 ELD-M fail in flight?
what an outright lie.Hornady told me they hadn't heard about this before, which seems, unlikely.
I'm assuming you're not accusing me of lying, correct?what an outright lie.
Correct. Should have clarified that the statement from hornady is an outright lie. Unless they fired the entire staff that knows about it and hired the janitors as customer service repsI'm assuming you're not accusing me of lying, correct?
Just making sure. I didn't pursue it further with them and sold the rest of the bullets at a loss.Correct. Should have clarified that the statement from hornady is an outright lie. Unless they fired the entire staff that knows about it and hired the janitors as customer service reps
May I assume that the vintage of the bullets you bought were close to last spring when you were doing load dev and having some come apart. That is, they were not from a year ago or that type of thing.Just making sure. I didn't pursue it further with them and sold the rest of the bullets at a loss.
I've starting working on a load using the 225gr eldm for my 300 prc. I am hoping that I have good success with those. I never had any issues with the 6.5mm 140 eldm, but I changed over to loading 140gr sierras after the shitshow that was the 147 eldm.
According to the date info on some pics, I bought a box (which was the pics above) in mid February 2022 from an Academy in Texas and I tried a second box in March which might have been from Brownells, but IDK? So this didn't happen yesterday, but also wasn't years ago.May I assume that the vintage of the bullets you bought were close to last spring when you were doing load dev and having some come apart.

I decided they weren't worth the trouble. It seems like it might be a lot to lot kind of issue. Hornady told me they hadn't heard about this before, which seems, unlikely.
1:8 twistWhat was the muzzle velocity and twist rate?
Thanks for the insight, was this happening in a class recently?MV and Twist Rate are not the cause.
it is happening with factory ammo, factory gun, we had one in class doing it so often we could predict it and got some good video of it happening
You know what I’ve never had a problem with?Give them a try and see what happens. There are a lot of factors that can contribute to the problem: rotation rate (twist/fps), barrel type, number and style of lands, barrel age/condition, bullet jump to lands, how clean/dirty the barrel is, etc. Your configuration/use might be ok (or it might not).
Hornady knows this is a problem, and if pressed will tell you not to shoot their bullets faster than 290k rotational rate. They will also tell you about all of the things that can make the problem worse and why it is your fault.
Personally, I had the problems with 153gn A-Tips n a 6.5PRC. I did not have a problem with the 147ELDs, but did not shoot as many as the ATips. I did not have a problem in my 260 Rem with Atips or ELDs, and I regularly shoot the 110 ATips in my 6CM w/o any problem.
What kind of barrel do you have and how fast is the bullet going?You know what I’ve never had a problem with?
Any berger from the LRHT line.
And I’m using the same barrels the 147s were blowing up in.
Hornady told me it was my barrel.
See post #1What kind of barrel do you have and how fast is the bullet going?
Same here. The barrel that was blowing up the 153gn A-Tips was just fine with the 153.5gn Berger LRHT bullets. That was a 26” Bartlein 5R 1:7 barrel with maybe 1100 rounds on it, bullet speed ~2980fps. My point was that there are a lot of variables and the 147s might work, you don’t really know until you try. If you can get the Bergers and don’t want to take a chance of losing bullets, that’s the way to go. But some people like to experiment, or maybe have a bunch of 147s to use up.You know what I’ve never had a problem with?

Yep, exactly. Same barrel that had all the factory hornady ammo blowing up was the same barrel I won the NF ELr last year with. According to the hornady rep, my barrel was the issue…Same here.

This thread was quite a read as I've looked into some faster twist options at sea level for heavier 6.5 bullets. I did notice Hornady's site for both the 147 ELDM and 153 Atip say 8t 'minimum recommended'. Sierra 150g states 7.5t min and Berger 153.5 1:8 or faster.Yep, exactly.

When I was shooting the 153gn ATips, the box said 1-7.5 twist minimum. They also published 6.5PRC load data showing velocities of 2950-3050. But if you put those together, it spins faster than their recommended max.This thread was quite a read as I've looked into some faster twist options at sea level for heavier 6.5 bullets.

I've only shot them in a 6.5 PRC at higher speeds (i.e., 2950 to 3050) in a 1:7 barrel, but they both shot well with a SAAMI chamber. They are very long bullets, so the bullet position in the cartridge in not optimal if you use a short action. I got slightly better precision with the ATips (when they didn't blow up) than the Bergers, but it was very close. I did find that the 147s were easier to load for, but overall performance was better with the heavier bullets.One thing that I’ve noticed is that the 153.5 burger bullets don’t seem to shoot very well in any gun that I have that has a standard SAAMI chamber…
I currently have a PVA Osprey 1:7 and that would be the fourth barrel I’ve tried, and it doesn’t really work well either for those very heavy bullets.
147 ELDM I can shoot all day long and have no issues whatsoever.
Pretty much go to round…
The highest velocity, I’m seeing with those are 2750, and I’m obviously not having any problems with them exploding.
Are your thoughts on the SA/bullet position b/c of needing to load in an SA mag or were they so long that even single loading block shooting causes you to cram them in? I bench rest single feed so as I keep looking into one of these 7.5t options want to make sure I don't run into that, but am hoping you are alluding to needing mag feeding.When I was shooting the 153gn ATips, the box said 1-7.5 twist minimum.

For short action mag feeding. I was limited to 2.95 OAL by the mag. For single feeding, I could have gone longer. For the SAAMI chamber, I could have gone to 3.035 (to jam) if I was single feeding. For single feeding or a long action, I would consider a longer free bore than the SAAMI chamber, but I never modeled that so I don’t know how much longer.Are your thoughts on the SA/bullet position b/c of needing to load in an SA mag or were they so long that even single loading block shooting causes you to cram them in?

Searched for 147 ELDM jacket separation or bullets blowing up/coming apart down range on here and one dead thread with 7 posts about the 147 and another on the 180 ELDMs.
Over the past 2 weeks i've talked to at least 15 people who have experienced both factory Hornady 6.5PRC and reloads using 147gr ELDM bullets coming apart between 40 and 150 yards down range.
June 13/14th and 20/21st I had back to back matches. The NF ELR outside of casper and SnipersHide Cup in eastern Washington. I planned on shooting factory 300PRC 225ELDM for the ELR and factory 6.5PRC for the hide cup. Normally I would reload but I bought a house just before the covid bullshit and i've been putting in new flooring. I haven't even unpacked my reloading equipment. I had time to prep and test the 300PRC which was showing good results, I didn't bother testing the 6.5PRC because I was going to shoot the same lot and barrel that I shot at the NF ELR last year and had zero issue.
At the NF match, the factory 300 worked pretty well, yet one of the guys in my squad (Steve) was going to shoot factory Hornady 6.5prc. During zero, he got 5 round on target which grouped around 1-1.5 inches. Pretty horrible really considering last year that same rifle with the same lot of ammo was shooting 1/2 inch. He asked me to zero his rifle to double check he wasn't just screwing something up majorly. I got behind the rifle, double checked turrets were zeroed, picked a fresh shoot-n-see and broke a shot. Nothing. I had @NoLegs24 get behind me and watch over top to look for anything out of the ordinary. Second shot I took, I watched a banana appear about 6 inches away from point of aim and I hear laughing behind me as he said there was a white puff around 40 yards down range.

I passed the target around to a few people at the match and multiple people spoke up saying they have either experienced the same thing themselves with the 147gr ELDM or they know of some who has had the same issue.
Luckily we drove to Wyoming and most of us brought 2 guns. Steve was able to use a 6x47 which he got some hits at 1400 with.
After the match, we drove home and because the SH cup requires short action calibers, I swapped to my 6.5PRC barrel (Bartlein 5r - 1:8) and had a bunch of factory hornady. It worked great last year so I figured it would be fine this year as well. Fast forward to thursday and we flew out to Spokane. Pulled my rifle out to check zero since I didn't even have a chance to shoot between getting home from Wyoming and flying to Spokane.
Fuck me, wouldn't group for shit and bullets were blowing up just past the 100 yard line.

Here is a link to the video of it blowing up. set playback speed to .25 and quality as high as can go and you will see them pop then impact the dirt
Cleaned the shit out of the barrel to see if maybe there was a carbon ring increasing pressure as velocity was at 3060. Removed all carbon and no luck. still popping them.
This was damn frustrating because of all the time and money spent to get to this match just to have the rifle go down due to factory ammo , which worked fine last year.
@NoLegs24 was shooting a 6.5PRC also, our barrels were ordered together and probably came off the line one after another from bartlein, they were both chambered one after another by Matt at Sawtooth rifles. He hand loaded 140 Nosler RDFs at 2950 and had no issues. The issue here comes down to the 147 ELDM. Factory ammo should not come apart like this.
According to the RPM formula (12/8 = 1.5*3060 = 4590*60 = 275,400RPM) these 147s should not have been coming apart. Anything over 290,000 rpm is the danger zone for bullets coming apart.
Ended up getting lucky and borrowed 2 separate rifles. Most of the match I shot an Axial Precision chambered in 25SST in a manners EH1A and a steiner m7xi MSR2 with a prototype Elite Iron suppressor. When ammo was getting low, I swapped and shot a 6.5cm
anyone else see the 147ELDMs come apart on them?
Depends when you purchased the ammo or projectiles. I was told by some reliable sources the jacket thickness was increased at some point and they haven’t been blowing up as much anymore.Ive killed 3 elk, 2 antelope, and 4 deer with the 147s out of my 6.5 PRC. All one shot. 3090 fps. Not a single hiccup. Got about 300 rounds through the gun. Must have got a good batch.
