18" 22ARC
- Thread starter Forrest84
- Start date
We just got in some Geissele 18" 6mm ARC rifles, and before ordering them, had several conversations with people who used them competitively, and in the field. Very impressive results, but I was examing the rifle and the results and did not ask about the ammo.
Also curious on real world velocities for the 18” 22 ARC barrels.
I have an extra 6 ARC upper sitting around for use as a dedicated thermal rig. Now that 22 arc is out, I’d prefer to flatter trajectory at night and debating swapping the 6 arc barrel for a 22 arc

Any chance you could get me a good picture of the feed ramps on that Rainer 6 arc barrel?
I lost intrest in gas guns years ago but if i can build something in a small frame gun no longer than 18" and run heavier than 77gr at the right speed with factory i may build me something.
The 6 Arc with 58gr Vmax load from Druid Hill is pretty darn flat out to 350 or so.

Curious on 22ARC velocities also. I’m thinking of picking up a ready to rock barrel from Craddock.
Max charge for CFE gave me 2690 fps
LVR 2710
TAC 2600
Staball 6.5 2450
I still want to try varget and staball match. I really wish someone would spec a powder with CFE223's burn rate with the temp coatings on it like staball. That would be best of both worlds.
Just got mine, 20" with brake. Hopefully get it broke in soon.
Just fired my 20" SOA Barrel for the first time this weekend.
Round count: shooting two days: 85 rounds total (including 15 rounds of reloaded 52gr SMK HPBT).
62gr ELD-VT: Avg FPS: 3176 with ES/SD (29/9.7)
75gr ELD Match: Avg FPS: 2993 with ES/SD (33/11.4)
88gr ELD Match: Avg FPS: 2716 with ES/SD (25/8.6)

18" Proof SS 22 ARC barrel and Hornady 88 ELD-M. Sample size 15 RD.
Brand new barrel - Will most definitely speed up. SD should come down.

Not an 18”, but for velocity comparison I’m running the Hornady 88’s in a Rainier Ultramatch 22” at 2764fps. In the factory offerings, there’s not a huge difference between the 18-22” barrels.
Hope to test the 85.5’s out with H4895 later this week. That combo should up the velocity just a bit.
