264 WM and RL25 vs RL26

[tbrice23]

Eldx are certainly different.
68.5 gr with VLD = 3186 fps
68.5 gr with ELDX =3260 fps
maybe they like lower velocity.

I was wondering about those progressive twist barrels myself. Maybe start a new thread and see if anyone knows anything about them.

I would be interested in R-26 first hand 264 knowledge! I went crazy and ordered several hundred ELDX. Hornady bullets are plentiful around here about everywhere and bergers are special order items that weren't available one too many times so I'm married to them until this barrel is likely done dealing. The jacket fouling of the ELDX just plain sucks. I *think* it's skeiving the jacket. In my 9 twist barrel the first 3" of barrel get loaded up. I haven't recovered any in any condition to be able to verify that. I have recovered one from my Grendel, but the initial velocity was only 2089 fps and it showed no skeiving issue when recovered. I haven't shot the ELDX from my 6.5/06 yet and likely won't mess with it in that rig. In my 264 win mag, with Berger 140 hybrids I didn't see anything even close to this with 100 rounds between de coppering. I'm hoping that the transitional rifling will amalgamate that even further. I have a solid case of ELDX buyers remorse, they better be pure hell on the deer or they will be in the classifieds in a few weeks.

Maybe I'll have time to experiment with them and Rl26 in my 264wm soon.

I'd be willing to bet they are less copper fouling in my 260 Remington. I might try in it too.
It's so wild, Amax NEVER had this effect regardless of cartridge/caliber/ barrel/velocity.

What's your round count, if you don't mind sharing??

 

[tbrice23]

Exactly 165 rounds, including foulers.

Nice. You've got a long career ahead enjoying that rig. I am currently down to just one 264 win mag, with 571 rounds since new. I sold my previous to a friend with 720 down the pipe, he's still shooting it sub-MOA.

 

[tbrice23]

That's great news. I keep 'em cool.

I've never had a reason to shoot anything with any of the 264 win mags I've had over the years more than twice, ever. That being said, I haven't had the opportunity to go after anything bigger than whitetail deer. I site in my cold bore shot dead on at 200 and rarely needed a second round, unless I just plain miss.

Have you ever heard of Dyna Bore Coat?
I bought some at MidwayUSA, since you are running ELD-X you could try it and see if it helps the coppering issue.

I've never felt a need to use it untill a barrel starts firecracking towards the end of its accurate barrel life to stop copper, or on a rough factory barrel. Just a thought it might be worth a shot .

They tend to put a severe strain on the jacket making bullets do some strange things and copper foul pretty bad.

I got interested in them at one point and started a thread here and the guys who know more than I do about actually building guns told me the above so I decided against giving them a try.

I have not heard of that. I'll take a look and do some research. I Learn something every day!

one of my bud's use 42 grns of re 22 with 140grn berger with great acuracy

 

[tbrice23]

13 shots at 200. I changed the seating depth to .005" jump.

Not sure why it appears that I got 2 separate groups ?? I took over 2 hours to shoot these, so maybe wind or light conditions changed slightly .
Still all 13 was just over 5/8 moa.

Also it appears that this barrel is still picking up velocity with the same load, which is common in my experience. I think the seating depth change may be responsible for about 10 or 15 fps.
