New 22cal 88GR Hornady ELD-M

[steve123]

I just got a Shilen 1-7" prefit in .22br and it's shooting really good with 88 eld's and RL-16 @ 2,950

Did you order it direct from Shilen or I should just ask where you sourced it?

The Wylde chamber should have 0.062" fb. How do the 88s look once they're seated in the case neck for your setup? Is the boattail/bearing surface junction below the neck/shoulder? A 0.062" fb chamber seems like it would be more than a little short for a bullet of that weight/length and might put it down below the neck/shoulder. Although they certainly could be tuned to shoot that way, I suspect it would result in a lot more pressure to hit a given velocity than with a freebore something more like around 0.120" to 0.150". I may have seen the figures, but I don't recall exactly how long the bearing surface/boattail is on the 88. If it's a lot shorter than other 80s/90s, the Wylde might be ok.

Oh, the bearing surface is definitely below the neck shoulder junction but if you want to run them from mags it's going to be a necessary evil. I'll post a picture a bit later

Showing some promise.

In the 223. My OAL with .025 jump from a 223 wylde chamber

Seems a ball powder would be needed to avoid compression. PP2000 would probably be good in this situation when mag feeding was needed.

While I am compressing H4895 slightly I'm not seeing any downsides to it. If I compressed more I'd probably see bullet deformation from the seater like I see with 77 tmks and varget.

I've used H322 with the 80.5s in a 26" barreled .223 Rem and gotten good velocity without pressure issues. They weren't seated nearly as deep as your 88s (them puppies are wwaaaaayyy down in there, aren't they?), but I figured with the [relatively] short barrel and the bullet seated deep, a very fine grained, faster powder ought to work well. The H322 gave me better velocity in that context than either Varget, H4895, Benchmark, or 8208 XBR. Anyhow, thanks for posting the pic Ian!

 

[InkedIan]

I have some 2000mr so if I try it I'll report back. I know it's on the slower side but it's all I have ball powder wise.

Anybody shooting this in a 223ai? Curious if it can work at polymer AICS mag length.

I used 2000MR in a long-throated Bartlein 30" medium Palma 223 with 90VLDs; found I can get about 50fps more with N550 than I could with 2000MR at 2890fps. It's been several years ago, but as I recall, accuracy with N550 was a bit more consistent as well. Not a huge amount of difference, and to be honest, I'm sure I was a bit biased in favor of N550, since that's the powder I'd used with great results for years in AR15 SR loads with 90s.

Assuming your throat is appropriate. My .090" throat keeps the 88 ELD in fine shape to fit in .223 Ruger AI mags.

I've been shooting them out of my .223 rem with good results. With a stout load of XBR they are right at 2900 in a 24" Muellerworks. LC brass, cci 400 primers. I don't know what the FB is on the reamer but 10 thou off the lands is right around 2.500" They ran fine out of a notched Accurate mag. I wouldn't expect to get more than 3-4 firings at that velocity. They group well and shoot in the same hole as my 75 ELD load, I was able to win a club steel match shooting them interchangeably. Also the price is right

I'm surprised you're getting more than one firing, that is an extremely hot load. Pushing 90 VLDs at 2850 fps with H4895 in a 30" barrel is only good for two to four firings, and your load is clearly even much hotter than that.

I agree. It's a very fast barrel, similar loads in my other barrel were 60-70fps slower. For day to day shooting the lower node at around 2815 is more practical.

OAL - 1.242"
BTO - .615"
BT - .200

We're close, I got 1.243 average.

 

[deadduck357]

Has anyone gotten good results out of 1-7?

 

[Evlshnngns]

Group labeled 9 is 22.5 gr rl15 in a 7 twist. Hopefully it will do the same with more powder.

 

[McFred]

I threw this load together to test and came up with this:
.224 88 ELD-M
3298fps using Reloder 26
26" 1:8 twist (1.40 stability factor per Berger's calculator)
Drop seems to jive with Factory G7 BC out to 950 yards.
200 yards prone with a bipod/rear bag.
5 shots upper left, 6 in the middle.
