62 eld vt

If these 62’s are in fact 75 gn match jackets with less internal lead. I’m not thrilled at all about their inception. I could not get the 75 gn match bullets to shoot in any of my three 22 caliber barrels. 7, 8 and 9 twist would just not find a decent load at all, but all three barrels EASILY shot tiny groups with Sierra 69’s with multiple load combinations. Some bullets just don’t work, period. My worst Sierra groups were better than my best Hornady groups in those instances. But Vmax’s and A maxes shot great so I could not tell you what the issue was ???

Are you shooting these at mag length or standard length or something like that?

It’s been quiet a while since I tried those 75 gn match from Hornady, but I tried every conceivable combination when I did. Mag length all the way out to jam length and everything in between. Ironically my 9 twist gave the best results but still terrible. I believe the 7 and 8 twist barrels exaggerated their flaws. I remember getting two very distinct groups. If I fired 10 shots, it would look like two different five shot groups. I believe they were just junk bullets. I know it was the bullets because Sierra 69 smk’s and Nosler CC 77’s easily shot 3/4 moa and smaller in most attempts.

The 75 ELDM has, for me, been difficult to make shoot bad. The same for my customers. It is a go to bullet with great performance at a cheap price.
 
A while back I used H 75hpbt's a lot - around 9K/year. Over a couple years, I had to return two of their 4K count boxes because the bullets didn't meet Hornady's accuracy requirements. I could not get less than 3 1/2" 'groups' at 100 yards. Out of 10 shots 7-8 of them would be on call and under an MOA with the other 2-3 off call by 2-3". Each time Hornady did the testing on 50 samples they had me send.

Based on this experience, I've concluded that Hornady's manufacturing process controls allows the process to 'wander' out of spec => from time to time customers will received bullets that don't shoot well. Assuming/if this is what's going on, it might apply only to the high volume bullets [e.g., 75HPBT].

Since it's been 6-7 years, maybe Hornady has tightened up whatever they needed to do.

ETA. To clarify, in the three years I used the H75's, except for the two 4K count boxes, they all grouped just fine [i.e., in prone with a sling, < 1 MOA and often < 3/4 MOA]

I think they did, frankly. I thought Hornady bullets were inconsistent in the past. They are way better now. At least with ELDM series. They seat at about a thou of variation. Slightly worse than Berger.

Wow - that would be disheartening to get a lot that bad. The only Hornady bullets I've ever used were the 52 AMAX and pretty much all the V-Max bullets in .17 and .224", as well as 75's in 6mm. Fortunately, I never encountered any bad lots - at least that I could definitely attribute as the bullets being at fault. I did buy some 87 V-Maxes to shoot out of a 6BR with an 8-twist and it was "shotgun city" with five powders and various seating depths. But that was only one tube. I never had any other lots of 87's to compare with - so it would be unfair to say these 87's are bad. On an established load, I really can't say that I've ever gotten a truly bad lot of bullets from any manufacturer as you described getting - or maybe I did when doing load development with a new bullet and wrote those various bullets off prematurely as "non shooters" for that particular gun. One can bet that when a shooter tries a new bullet and it shoots like crap - he is not likely to buy more to test another lot wiht that rifle.

I was loading a fair number (200, I think) 108 ELD-Ms and stopped measuring during seating. The first fifty were the same number. Very consistent, IMO.

What seating depth did you use?

I got back out to the range yesterday to give those 62's another go in my .22 Nosler. I tried five more powders in it. Turns out the IMR4166 shot exceptionally well compared to the other 7 powders I have tried in it. It was better at all seating depths and powder charges. Figures - I only have a few pounds of it and seems to be tough to get.
 
Still trying to find the right load but so far I absolutely cannot get these 62eldvt’s to shoot in an 8 twist 22bra.
 
My savage 223 with a 9 twist will stabilize and shoot the old 75 amax very well. Do you think these 62’s will stabilize in my rifle ?

Also what jump are you using? As mentioned, they need to be pretty close to the lands.

I have read a few guys needed to run them close and admittedly I have not tried that yet. I’ve ran them between 10 and 30 thou. I guess I need to set them out some more and see what happens.
 
I would think probably not. If I had some and wanted to know, I'd load a few and see. I wouldn't buy any just to see.

FWiW. Litz's stability calculator shows a stability factor of 1.36 at sea level, 60*, 1:9 twist and 3400 fps. So, it might be stable enough to group small but loses some BC.
