Home Forums Hunting & Shooting Custom Rifles & Wildcats Considering a shorty 308, 18" or 20"?

Yes, thanks for the link sgt. There are some rifles on there that are pretty close to what I had in mind. I'm going to go with more ofa sporter weight because I'll likely pack it hunting. I'm thinking 18"#4 in a B&C should come in about 6.5 pounds without the scope. A 3.5-10 with m1's and I should be 7.5ish.

If an 18" will run 155 scenars at 2800 I'll be happy.

Sounds like a plan!

I've shot a 30-06 with an 18" barrel and it was a brute.

The .308s virtues are it's accuracy and mild manners. An 18" barrel for me sacrifices the mild manners part. I would go at least 20" as the noise and blast created going down to 18" is exponential.

Not possible.

.308 win (10 twist)
21" PAC NOR just slightly heavier than a mag contour and fluted. MCM- HTG stock. I've never weighed it but she handles like a dream and will stack 150's and 165's.

Guys he said threading it for a can!!

Noise is not a factor!

I would go look at what Remington is doing and only use an AAC can.

I get it... 2,800 with a 155 is NOT possible @ 18"... (ie, safely).

Agreed 100%!

I ran the 155 over Varget through QL last night, 2.800" OAL, 18" barrel and started adding powder, I stopped at 2800 fps @ 72K psi.

What does it say for IMR8208XBR?

18" barrel, 2.8" OAL, 2669 fps @ 60.3K psi with 8208XBR

What does it say for 51g PP2000MR and LC LR brass. I'm getting over 2700 from a 16" AR-10 with 155's. But I admit they may be warm. My 20" 308 ran 155's at almost 2850. I'm just guessing that 2800 from an 18" is possible but I've been wrong before.

What OAL and temperature?

2.83" let's say 70 degrees

I fought the short barrel thing for many years. About a year ago I built a 16" .308 and will never have a longer barrel on a .308 again. It is almost my favorite rifle now, even though the .308 is a turd.

If you shoot a centerfire rifle without ear pro you're going to suffer hearing damage. I wear a set of electronic ears every time I pull the trigger. No more worries.

I get 2520 with a 175 SMK
I get 2625 with a 168 AMAX

Nosler E-Tip 168gr factory ammo runs 2500fps.

MR2000 is not in my version.

GT, ya got a pic of yer carbine? Wanna see Volunteer State blueprints.

Been winder-licken' that snubnose 700 SPS .300AAC @ Wally World, but the snipershide thread has got me thinking bout a bob-job on my LTR .308 as an alternative.

That'd put me severall C-notes closer to a .30-cal. Suppressor and can just protect the threads wif a Noveske Pig to divert noise away from the truck cab during the year-long wait for a stamp.

Wishin like fire I'd bought that Weatherby Ultralight .308 after the T&E years ago. Its fluted SS barrel SS bbl woulda been ideal for these purposes at 16.25-in., not to mention a bit more wieldy on foot.

Wouldn't the fluted LTR barrel look kinda...goofy...after being cut?

Pretty is as pretty does.

It'll be Kryloned to a fare-thee-well or dipped in Kryptek, so only close exam will reveal the aesthetic faux pas.
