Glad to hear the 62 ELD VT are working well. I plan to load some in both 22CM and 22-250. Both 1:8 twist.

Found a couple powder charges with the 85.5gr that seem to work, 3205(bottom 5) and 3235(top 5). Felt a few in bottom group break high and right, scope is farther back than optimal for prone shooting and felt a bit scrunched up.
On a side note, has anyone saw or dealt with a first shot faster than rest in string? For some reason, irregardless of powder charge, the first rd in every 85.5gr load is 35-45fps faster. Confirmed with magnetospeed and Garmin. Switch to different bullet and it's normal. Rd Robin between 85.5 and 95smk strings and first rd of 85.5 was fast, normal speed on 95smk. Any ideas? I don't think it can be barrel or loading technique as it's consistently first rd and always/only with 85.5s.
It's not powder related as I was using same powder with 95smk. I've got some 90gr vld ordered to try. If the 85.5 shoot the best, I'll take them to 800 and see how they watermark.
What's a good starting load to obtain the highest velocity shooting the new Hornady 62gr ELD-VT bullets 26" bbl 8" twist?
Starting load. I have numerous Fast, medium, and slow-burning rate powders. Re#17 was suggested. In my standard 22/250, W-W 760 is king. In my 220 Swift 4064 and AA 2700, produces high velocities.
Out of those W-W 760 would be a good choice I think. I have ran 4000MR out of a 26 inch barrel at 3730 fps. My load was 44.5gr but of course hasn’t been pressure tested so use at your own risk.
Currently I am using Reloder 15.5 and my max is 40.5
Just so no confusion this was with 62 gr VT

4000MR and Reloder 15.5 both will get 3500+ from a 1/8 20 inch barrel.
Don‘ t know if I would try the 62 VT if I were running a 1/7 twist due to RPM ‘s but I am sure someone is or will so that will shake out as more folks get their hands on them.
I might add Alliants 4000MR is a great all around powder that’s overlooked by most. It’s one of the top velocity getters in the 6.5 Creedmoor with heavies and is usable up thru all the Medium & Magnum cartridges. Also unlike all the overseas made Alliant powders the price hasn’t shot to the moon.
I might have missed this - which powder are you using?
I use the SAC seater and sizing die. I think they’re fantastic. The seater is great for everything in the bolt head family. If you do anything else in the creed family with the sizing die, there’s utility there. I started with a set of Whidden, the seater crushed the case.
Totally worth it for me. I load 22, 6, and 6.5 Creed. the sizing die allows me to taylor the amount of sizing to whatever brand of brass that I am using.
Whether it be Lapua, Alpha, or Hornady.
I load for the same calibers also and use the SAC sizing die for them. You also get the benifits of the neck/shoulder bushing.
edit: plus the expander operation all in one step
After a seating depth test, I settled on 43.1gr h4831sc and .010 off with 90gr vld. Shot them at 750 today to see how they watermarked, decent breeze from 4 o'clock. Right at 120ish rds on barrel and looks likenits sped up from the 3220fps this load runs.
I've found the loads I'll take to MT Prairie dog fields. 132 rounds down my new rifle. 26" Rem Varmint contour Muller works 8"twist bbl Bat Igniter action McMillian Game Warden 2.0 stock Trigger Tech Special trigger.
Alpha brass 41.0 gr of H4350 75gr ELD average velocity 3537 6.6 SD out of 10 rounds tight groups on a cold, windy day.
Alpha Brass 42.5grs H4350 behind Hornady's new 62gr ELD-VT bullet out of 5 shots average velocity was 3,844 MOA SD of 23.9 43grs out of 5 shots was 3,873 SD of 11.8same MOA accuracy Then I tried some 60gr Nosler BT with 43 grs of H4350 Peterson brass average velocity was 3,880 with SD of 16.3 and then 3 shots of 43grs of H4350 behind a 55grs Nosler varmingeddon for 4,040 FPS with under 1/2 MOA all at 100yds. My rifle doesn't like H1000. I wonder which of today's loads will be the hardest on the barrel. Also, there are zero pressure signs and no hard extractions.

Pederson data shows 43grains of H 4350 running a 80 grain bullets to be way over pressure.am I missing something? I just had a 22 CM built so just wondering just have to work up I suppose. where did you guys start say 41 grains .
My barrel sped up about 80fps and the solid load was now making faint ejector marks on a few pieces of brass. Slowed back to 3234fps Ave with a 4.8sd over 10rds. Here's the 5rds on paper, the other 5 were on steel, downrange.
Peterson srp, cci450, 42.4fr h4831sc, 90gr vld .010off in a 24" 7tw criterion.

In my rifle 42.0 gr of H4350 was above 72,000PSI with 75gr in Lapua necked down brass FWIW. There is a reason Hodgdon doesn’t show any data with H4350 with any bullet weights in 22Creedmoor…..just say’n
Just wondering how many rpms are these bullets going to take before they start not getting to the target?
I thought about 3400 fps in an 8 twist bbl was about the limit?

Are you using Large Rifle Primer brass for your loads on the 75 gr ELM?
I’m still shooting some Copper Creek 75ELMs and I’m in process of start loading for it. Got plenty of H4350

Yes, Federal 210 LR Match. What velocity are you getting out of the Copper Creek ammo?
Not sure they want you to do a load pack and buy at least 100 rounds and they’ll give you the data
I pulled one apart 80 gr ELD,it looked like H4350. Out of my 26"bbl rifle I was getting 3350 with close SD
Savage 110 donor action, MDT LSS Chassis, Criterion barrel 24" 1 in 7" twist. 77 grain SMK over 36.5 grains of H4350, 100yds. COAL - 2.570, didn't chrono. QL predicted 2963fps at hair under 44K psi.

It was 41.3 grs, now am I certain it was H4350? It sure looked like it, or was it Re#16
Don't have any hi res pics of that powder, do you? All the re16 I have is dark charcoal to black and is irregular cut/shaped pieces. H4350 is kind of a greenish-dark grey color and is pretty uniformly cylinder shape and all kernals are very close to same length.
I’ve ran into a similar issue. I have a 7 twist criterion pre fit and I wanted to run the 95 smk and I did but with the occasional issue that got more common as the barrel wore. So I switched to the 90 smk and and I ran great for awhile at 3280fps until I had some start hitting sideways or huge poi shift. I talked to Sierra and they said the 95 smk was designed for long 223 barrels with max velocity of 2900 fps and the 90 smk was designed for the 224 valkery again 2900 or less. He said with the thin jackets you are more likely to see issues as the throat begins to fire crack. This is on point from what I saw.
95gr SMK’s at 3080fps got me my first ever top 5 finish in a PRS match last Saturday. I could hear the RO’s while I was shooting saying “that thing is a laser beam”.

No I’m going to run 75 & 80.5 grain bullets in a 1/8 twist.
So far so good with 90gr bergers and h4831sc in a 7tw criterion at 3225ish. Original load was 3210, barrel sped up to 3280 but still worked fine. I backed down to 3225.
Awesome thank you. Trying to figure out the twist & potential projectiles for my next 22CM AR10 barrel.
Hmmm One of these cases, is not like the other
hey, I got one pop quiz. How do you increase your velocity by 150ft./s without adding any powder super cheap way to increase speed.!!!
NOT…
I wouldn’t max charge any round before you work up to it but hey, do what you want
federal cases are not top quality like Peterson and I’m willing to bet that Peterson would easily take the pressure
I found the main culprit=.
Neck tension= not sure how these were so work hardened but damn couldn’t get them out with a press mounted, collet bullet puller w/o destroying or severely marking the bullet.
A tight reamer /the neck area probably needs a few .00’s than what it has.
all Schilling barrels that I have, that are chambered by Schilling, have a very low thousand space between the neck and the chamber wall . (too bad about the spelling, but I can’t spell it. I’m not going to.)
should have anesled it and maybe even cut a few thousands off the neck
What an interesting learning day I had
Happy I didn’t flame-cut defiance bolt head
I’m sure there’s difference in case volume as well why one was OK and one it wasn’t..

Has anyone had any luck with the Hornaday 75 edlm s In their 22 CM I have some Berger 80.5 but Hornaday is cheaper?
I've had great luck with them in 22cm's. Seated 50k jump at 3150 in my 18" barrel, 40.6 H4350, very mild load, 3350fps in my 22" barrel with another 0.8gr powder.
