What sort of speed would you get with 180 eld m with 26” barrel.

I’m guessing is a 7mm blaser mag improved
What sort of speed would you get with 180 eld m with 26” barrel.
It's a terrible name for starters :D I'd say a standard Blaser mag would do 3k without having to form cases?
@Dreamer might has some data.
@Dreamer might has some data.
Feckn gremlins are causing double posts :wtfsmilie:
Didn’t have it very long but was getting just over 3000fps with 162gr in a 24” tube

Can get 3000+fps with 180 ELDMs out of 24-26" standard 7mm Blaser :cool:
It does sound like a cool cal I have seen a few improved versions but wonder if the extra hassle would be worth the potential gain
What powder and grains please?Quote:

How many 24" 7mm R.E.M. Mags can do 3000 with 180eldm's?
What pressures are you getting to achieve that?
Very keen to hear some real world results too @Kiwi Greg
There is an easy way to find out, do what I did.Quote:

I would have thought an easy way would be ask the guys that are running one unless it's some kind secret?Quote:

Cheers Danny thanks for the info
Thanks for the info. Looks like it would be a great fit for the tikka.
Instead of a cartridge run at max to get decent velocity like the 7mm blaser go with the bigger 28 nosler run it well below max and achieve the same result and better barrel life if you were into shooting steel with the knowledge that you can stoke it up ffor hunting at LR.
Rem700, 28" bartlein chambered in 7 blaser mag.
180eldm, 3150 fps 2225
195 eol, 3100 fps RL33
Round count approaching 1k, still shooting great, not chasing the lands yet.
Cool cartridge.
7 saum, 28" truflite
180eldm, 3000fps 2217
1/2 grain off my max, so probably in the 2900's with 26"
Awsome cartride!
@Tony930 how do you find the Blaser mag brass eg quality and strength?
Just get a 270 @camo wsm

How many grains 2225 are you using with 180 eld M ‘s please?Quote:

69.6 2225, hit pressure at 71.2, was running 70 fps slower when first ran this load, don't know if was because it was lower temps (winter) or barrel was new, maybe a bit of both.
Usual stuff, each rifle different, work up.
I was going to suggest 69.5-70, but every ones rifle & scales are different :)Quote:

That data is for the 180 eld-m which I am getting great accuracy with. Havent cronied lately but ballistics program works with 3050fps set in it. Verified out to 870 yards, semi verified to 1180 yards, need to revisit that when there isnt 15+mph wind howling....
