Anyone loading 6.5 Creed for a gas gun?

[Pappabear]

We loaded up the 168 and 178 ELD's in 7.62 for my LMT MWS and it cycled them like a dream. But that gun eats chews spits anything.

22" JP barrel with JP high pressure bolt....

39.9g of Varget
123g Hornady A-Max
Hornady Brass
dont know the primer
2.800(whatever mag length is in a pmag)

Shoots 2900fps. ES and SD were both REALLY low(dont remember the numbers off the top of my head). Confirmed on 6" gongs at 900 yards... Numbers were maybe .1-.2 mil off of JBM drop numbers.

So far ive got 2 loadings on each piece of brass(started with 1000 brand new), if I get a 3rd loading I will be surprised. Hornady brass sucks, gas guns eat brass, im pushing the shit out of it.

ETA: JP, when I built my gun with their barrel, was recommending the lighter weight stuff in the gas guns. They had written a good paper on it and the reasons why. I believe they could get much faster speeds without pressure issues and the lighter bullets, even though a bit less aerodynamic than the heavier stuff, flew better due to the speeds.

I'm just about ready to work some loads up for my bolt gun (browning X-bolt). Hornady Precision Hunter 143gr ELD-X was .60 moa out of the box for me. Also tried the cheapo S&B 140 FMJ which was around moa. I'm curious if the ELD-X or ELD-M stuff feeds well out of the magazine for you semi-auto guys at factory SAAMI seating depth. My mag can fit up to 2.889 COAL which also happens to be where it touches the lands. ELD-X shot fantastic with the jump from 2.808 factory COAL though.

Next on the list to try is American Gunner 140gr and 147gr ELD-M.

I may be crazy, but I love ball powder for ease of measurement. So Ramshot hunter is going to be my first attempted powder.
Also H4350 is nearly unobtanium locally. Too many 6.5creed bros around here.

The ELD 140 and 143s have fed without incident for me.

Re. 4350; same deal here. When I started this 6 months ago, 4350 was not to be had. I ran across 3, 8’s of RL16 which I’d worked up load for. No regrets at this point.

Because Pappabear was buying it for a barrel he did not yet have.

Masterful planning. (:

Here's the chronograph data. I'll only run a series of 5 shots to collect the data- good enough for government work and I don't want all shots with the Magnetospeed hanging off the end of the barrel.

Pretty happy with the velocity of the 123's / Varget combo. I could push either one harder- I have not hit the top of the recommended loads, plus I am using the JP high pressure BCG in case I want to run a little hot.

S-D of 7.4 / ES 17 isn't bad for using a cheap powder scale, plus the gas gun X-factor. It's worth about 4.5" elevation variance at 1000 yards. Compare to the Winchester Match 140 factory ammo, with a ES of 93 and a S-D of 34.5. That would be frustrating at the 1000 yard distance.

What is your barrel length?

[soulezoo]

Not a gas gun, but I ended up with RL16 myself. Pushes the 143 eld-x faster than h4350 with same consistency and great temp stability. For the ball powder crowd, I had good results with superformance for velocity. Just not as consistent as RL16. So 16 is my powder...

[Pappabear]

It appears R16 is a legit 6.5 powder. This thread intro's Varget to the table too, interesting.

Good to know about RL16. I may try that out next. Thanks for the info.

I've also been thinking to try Superformance. Although that is supposed to be temp sensitive as well.

Great thing is a lot of what is being discussed can be ported to my other rifle as well.
