I didn't see a specific thread for semi-auto 6.5 Creemdoor loads, so here goes. If possible, Please state your semi-auto platform (eg GAP-10, JP, Mega, etc), barrel length, bullet, powder and charge weight, brass and primer, and muzzle velocity at what temperature.

JP LRP-07 and Seekins SP10 6.5cm 22" Barrel each

42.3, H4350 140 ELD-M

Shoot from Temp in the 50s F to 100 F

Both produce on Average 2720 ft/s in that temp range.

Ive left my ammo in the sun by accident and get really bad swipes.

Every gun is different, so am not sure what the purpose of this thread is? not being a jerk, am just wondering the point.

Variables you asked to be defined is a good start but more importantly you need to know:
Barrel blank manufacturer
Gas system length / port location
Gas port size
Buffer weight
BCG weight
Buffer spring
Trigger (yes, it does have influence and more than most would think)

20" WOA 1:8 twist, rifle length gas. Slash heavy buffer, standard spring and bcg.

123 Scenar, 42.6 gr H4350, Fed 210m, hornady brass, 2790 fps. Loaded to 2.760 COAL, I think.

Is your WOA short throated, or is there a particular reason for running at 2.76 OAL? PMags will let you approach 2.81, ASC and others to 2.85+. Scenars shoot well for you with that much jump?

AR 10 with PWS MK 2 lower and geissle trigger. Upper is Aero precision upper, BA 18" barrel, adjustable gas block, and lantac BCG.
Rifle is a hammer with American Eagle 140 grain BTHP and Prime 130 grain ammo.

Best reload for this rifle so far is:
Hornady brass
Berger 130 grain AR Hybrid bullet
CCI BR2 primer
42.5 grains of 4451
2.800" OACL
approximately 2650 fps out of this setup.

Round delivers sub MOA performance out of this rifle and a 24" Bergara BMP at 2750 FPS

Very happy with this combination.

Anyone have data for 130 ar hybrid bergers or 130 hornady eld with h4350 hornady brass.
I'm shooting out of a 22" gap 10.
Also what kind of velocity should I be expect?
Thanks

Not sure with the newer AR style guns but guns like the Garand and M1A's hotter loads tended to beat up the actions from extra force. Bolt guns didn't have this problem until you got into over pressure loads which are bad for any gun.

I worked up 130ELDM with Varget and H4350. Varget was best. 22" JP barrel. 40gr, 2.835"COAL, CCI primer, 2851fps at 60F with SD of 10.8fps. It was a lazer till about 600, then the bullets inferiority shows up. It falls a mil short of its G7 BC at 1000yds and is horrible in wind. Dont waste your time. go 130Hybrid or 140hybrid/eldm.

24" Bartlien rifle +2 gas system.

41.2 grains of H4350 and 140 ELDm.
2720 fps

Factory Hornady ELDm gets me the exact same velocity and POI. Very easy shooting load, no pressure signs at all. Ran without a hiccup on a hot match. I've taken it al 42.0 without pressure signs but had better accuracy at 41.2 and thought it would be nice to match factory ammo.

How horrible is horrible? Looking at a 130gr based 65 build so gathering real world experience. Thnx.
