Test it out and see if you even need one. I am not currently using one but haven't measure a chambered round to see if it changes.

The second solution - use of a full-length bushing die - is the better option. This is the one that I use. It’s a bit of a pain in the butt, because you most likely will need to change the bushing diameter when changing brass types or brands (or even when changing lot numbers). But, when you get it right, it works well to produce consistent, accurate handloads.
Well, 25.2 looks pretty dang good to me, and 2719 fps is nothing to sneeze at.Good shooting!I've been running at max pressure with 88 ELD and it works but I'm stressing primer pockets too much. Barrel has speed up about 75fps since new so I think I can back down and maintain better brass life with good speed.
Here is OCW with 88ELD and CFE 223. Nodes at 25-25.2 and 25.8-26 (very hot load and 26 is known from prior testing). SD is my fault for changing shoulder pressure/bipod load for middle two groups. View attachment 6930998
What happened to this thread? The silence is deafening. Did you guys all sell your rifles? LOL!
They shoot much better in my 224's than Federal. All guns are 1-7 twist.i realize this is the reloading forum, but has anyone gotten and shot the factory hornady 88 eldm loads yet? any input, and any comparisons with the fed gm 90's?
I have been watching this thread, along with the other Valkyrie threads, and do have my rifle together and shooting, but am only shooting factory right now. Hornady 88 ELDM is doing pretty well in my 22" 6.7 twist Rock Creek barrel from Craddock at about 2750 fps. I've only had it out to 800 so far as I'm waiting on a scope, but the results have been very good so far. At some point I plan on picking up some CFE 223 and Hornady 88s to play with, but really do not have the time right now, so that will probably have to wait until the winter months. Really pleased so far with this barrel.
FWIW, the Federal factory Fusion 90g loads also did well in my rifle, but I'm comfortable with the Hornady results at this point.
Yes, it is correct. I double checked, using my Magnetospeed because of the listed box velocity difference. The ballistics so far are also spot on to the projected drops for 2750 out to 800 yards. There are no undue signs of pressure showing. I can try and remember to take a picture of the primers for you tonight as a reference.Is that velocity correct? You're 75 fps over the box-listed velocity of the 88ELD load (2675 fps) and that is set through a 24" test barrel. Does the brass or primer on your spent cases show any high-pressure signs?
Seems like it could be loaded pretty hot.
Here you go:Interesting info about the Rock Creek barrels. May have to look into picking one up.
Finally received notification that my JP barrel has shipped. Any recommendations on dies? I usually go with Redding but am willing to try others.
A lot of people like Forster dies in general.
It’s hard to wrap my head around why the first 50 rounds would determine the fate of a gas blockView attachment 6936067
So I just received my brand spankin’ new WOP 24” 1-6.5 twist Krieger barreled upper and this notice was inside:

I guess I’m gonna be loading up fifty 55gr SGKs over RL7 and break in the barrel as per John Holliger....
the letter said 'port.' guess they're saying it erodes with the higher initial pressures. i actually replaced my block after a few hundred rounds (of 75-90g) for another reason, and didn't notice any port erosion, but wasn't looking for it.It’s hard to wrap my head around why the first 50 rounds would determine the fate of a gas block
I get it. Following simple instructions is an easy way to hedge against screwing up an expensive barrel. Erosion of a PORT ? seems insane as it is literally full thickness of the barrel. I’m scratching my head but at the same time realizing most of this stuff is voodoo anyways.I figured he meant port and wrote block...
As I understood it, the longer bearing surface on the heavies during initial break in erodes the gas port.
At least that’s their theory for the moment .
As much as I paid for the barrel , I figure why not?

Niles Coyote has some testing that he did with Varget and RL15 on pages 1 and 2 of this thread.Has anyone tried RL16? Or Varget? Seems most people are using 17 or CFE but I was hoping to avoid just another powder to keep track of.
How did the factory 88 ELD shoot in your rifle? I shoot the 88 under handloads. Curious about the factory ammo though for substitute in a pinch.So I did the White Oak Precision recommended “gas port break in” on my Krieger 1:6.5 twist barrel yesterday morning. It was already 85F with 96%RH @ 0900.

What a pain in the ass with the BCG short cycling with the itty bitty 55gr SGKs.
The bore probably got cleaned more times that morning than it will be cleaned in the next three months.

I’m amazed the jackets of the 55s didn’t rip themselves off with a 6.5 twist....

I finally finished with that dumb shit and ran some Hornady 88ELD factory ammo. The rifle began to cycle perfectly.

Who’s running 95gr SMKs? Got any data?
I’ve got Starline and Hornady brass and a lot of RL17......
I've only shot a couple hundred, but am buying more. I like how they do in my rifle.How did the factory 88 ELD shoot in your rifle? I shoot the 88 under handloads. Curious about the factory ammo though for substitute in a pinch.
Bison armory barrels? Can anyone vouch for them?
For me, I've just been busy with other projects and shooting matchs. My valkyries will be making range trips again come October.
Yes I do, but I have not shot it with the 88's yet either. I will say the 88's consistently group tighter than the 90smk in my 22" Bartlien during load development, I'll be surprised if they don't shoot well in the 18" barrel.

My freebore seems spot on (RA UM 26") but chamber may have been run just a touch deeper than I'd want for best brass life. But it's a drill with 88ELDs. This was cold bore 10 shot group with virgin Federal. Had some trouble keeping recoil perfectly straight on the upper right shots.I mean freebore, not sure the terminology. From what others are reporting, RA did get the proper SAAMI reamer...not sure i guess i just want to confirm it.
