16-18 inch shorty rifles

Oh man more pics, I didn't see that one. Did you pick up a SureFire FA762SS?Yeah, it's a spec XM3 built by Bill Corley, picture is up on the page 47. No particular reason why I went with the 175 SMK's, just cheap, available and lots of data on them. It being the projectile the XM3 was chambered for was just an added bonus. When I run out of them I might try something else but the gun hammers with the 175's so I'll probably just leave it be. This was a 3 shot group to check zero before I took out it hunting last week.
I’ve posted the barreled action before but it got some new heavy shoes under it so a new pics in order.

Thanks, I didn't realize their line had expanded so much since the last time I looked them over. That certainly does look like their most compelling option for a lightish, shortish hunting rig with some adjustability.
I haven't shot it yet as it's currently -7⁰ out but they did switch the buttpads to limbsaver airtech which seems like an improvement
I picked up one from Capitol last year. Had to sell some ARs to get it. Also have an absurd amount invested in the brakes and that one flash hider. So i feel yaNope, I'm poor and they are unicorn dust at the moment.
Well here are our work rifles... one is a 20" the other is a 18" both 308.

Getting right at 2500 or so with 175 federal gold medal in my 16.5” factory 700 aac-sd. Bedded in walnut by yours truly. Planning to buy a sentinel as soon as I can get the scratch together.
Resolution for 22 is to do more of this. Been a couple years for no good reason. Form is a little rusty and I totally forgot how to call wind. But a short, slow 308 will teach that pretty quick

^^^ it is amazing how lazy you get shooting a bullet with a .6 bc, and then break out a short 308 and have to actually start reading wind. I will take my 18” 308 and shoot it and when I switch back to my 6.5 I can tell a difference.
16” barrel, 100% suppressed
110’s @ 3000+ with 748
125’s @ 2900+ with 748/RL-15/Varget
150’s @ 2750 with H4895
155’s @ 2615 with Benchmark (slow but very accurate)
168/175’s @ 2480-2620 with RL-15/Varget/SW Prec. Rifle
180’s @ 2500 with 748
185’s @ 2440 with RL-15/4064
190’s @ 2200-2400 with Varget/H4350
130’s pushed hard with 748 @ 3100+ (Hot, hunting load)
210’s pushed hard with RL-17 @ 2460 (single loading)
Dredged back through my old posts to find the info, but here are measured velocities for loads I've worked up for my shorter hunting rifles, some .308 mixed in.
20" 6.5 CM:

140gr BT @ 2,700 fps
142gr ABLR @ 2,730 fps
18" 6.5 CM:
127gr LRX @ 2,742 fps
129gr IL @ 2,795 fps
130gr TGK @ 2,740 fps
142gr ABLR @ 2,680 fps
140gr GD @ 2,670 fps
20" .308 Win:
178gr ELDx @ 2,595 fps
18.5" .308 Win:
150gr IL @ ~2,750 fps
16" .308 Win:
168gr BT @ 2,600 fps
178gr Amax @ 2,510
18.5" .30-06:
165gr SBT @ ~2,800 fps
180gr AB @ 2,690 fps
190gr ABLR @ 2,635 fps
16" 6.5 Grendel:
120gr GD @ 2,420 fps
123gr SST @ 2,430 fps
129gr IL @ 2,330 fps
2015 AIAT folder, bought used, low round count
Factory .308 1/12 barrel
Barrel cut to 17.850" at Mile High, TB CB mount machine timed
Thunderbeast Ultra 9
Vortex Razor HD gen 2 3-18, mill
This thing hammers. I've shot it next to a GA Precision FBI HRT rifle with a 24" 308 barrel and it simply kicks it's ass in terms of ease of use and features. I can hang with him out to about 750yards then the wheels start to come off. I will be getting a 6.5CM barrel at some point.
Edited to add:
Prior to the barrel work I was at 2480fps with factory FGMM 175gr and no suppressor. Got a little over 2" cut off the barrel (2.150" to be exact) and added the Thunderbeast suppressor. Chronographed the exact same ammo at literally the exact same muzzle velocity, 2480fps with the shorter barrel and can. Funny anecdote.
Cold bore shot from last month, 101 yards:
3 shot group from previous outing, FGMM 175 or 168, I can't remember:

This thread made me cut mine off
Oh wait...........that came out wrong.
16” bolt guns is where it’s at for me with .308…sub 700 and in…factory Howa heavy 16” barreled action:
Features:
Oryx Chassis
MDT 20 MOA rail
MDT mags
YHM QD Brake with Resonator R2
Leupold Mark 4 Rings
Arken SH4 Gen 2 4-16 MRAD
Solid package and under the $1500 budget I had set.

I've never built a bolt gun but have seen some that I'd love to build. where to begin...lol
What powder and load were you using to get those 6.5CM velocities with the 140/142gr bullets? I'm trying to get a load for 140gr hybrids and I really want to get about 2,650fps. I've tried H4350 and I may try Varget. Thanks!
Work up in your own rifle, etcetera and so forth....
20" 6.5 CM:
127gr LRX @2,850 fps (43.5 gr RL16)
140gr BT @ 2,700 fps (42.2 gr RL16)
142gr ABLR @ 2,730 fps (43gr RL16)
18" 6.5 CM:
127gr LRX @ 2,742 fps (same load as 20")
129gr IL @ 2,760 fps (43.2 gr RL16)
130gr TGK @ 2,740 fps (44 gr 6.5 StaBall)
142gr ABLR @ 2,680 fps (same load as 20")
140gr GD @ 2,670 fps (44.4 gr 6.5 StaBall)
Reloder 16 is my favorite in 6.5 CM, but I also like StaBall. I have RL16 loads for the 129gr IL and 140gr Gold Dot that are a little faster, but I have a more StaBall, so I stuck with those loads. Either RL16 or StaBall will give better velocities than H4350 or Varget, with good accuracy. RL26 is even faster but I haven't been able to find any for years. As an aside, the 180gr AB and 190gr ABLR .30-06 loads are RL16 and StaBall respectively.

They are the 4-16 50mm with a Mil C reticle. I like it so much I bought one for my personal shorty.
Anyone have a short barrel 7 saum, I am looking to run a 16-18 inch and curious what kind of speed I would get with the heavier bullets.
All my hunting rifles are shot suppressed, but as for when the velocities we're taken, generally suppressed for the 20" and unsuppressed for the 18". I melted the contact points on my magnetospeed a little bit mounting it to cans and shooting one too many rounds before taking it off, so I had stopped doing that for the most part by the time I got my 18" Cross. The 16" .308 velocities (also the Cross) were can mounted because there wasn't enough exposed barrel to mount to.
I honestly have never seen big velocity differences between suppressed and not, 20 fps here or there at most.

There is no bolt action "pistol" thread, and it is a "shorty" so I'll just put a photo here.
Good info. Those numbers suppressed or unsuppressed, or both?
Good stuff, thanks for the info @Gtscotty !
^ The weight savings. One of the Christensen Arms pistols is like 4 lbs.
I love my shorty pistol .308 gas gun but that thing is a PIG.

Positives and Negatives to both… but i have to admit i am impressed with some of the bolt pistols..
I am wanting one just to play with amd test out.

I’m at 12lbs with a loaded mag as pictured. The Arken is whopping near 40oz of that…
Got a project going much like yours. Curious what height rings your using? I plan on using the new Mbrace rings and will also have a 44mm obj scope.
Those are the 24mm (0.94”) height, and the scope has a 44mm objective.
I have a couple 18” bartleins that should ship by mid Feb at latest? Should only take a couple weeks to get spun up and shot in…. Bring your Q fix’s up to the ranch and you can shoot them in with me and maybe we can work out a deal?
If anyone is trying to move a 16-18” remington aac version that they are not using…let me know.
I am wanting to get into a shorty bolt rifle.

Ive just sold this b/a but figured Id slap it in the freshly coated ATAICS before I moved it on.
