Short Barrel Truck Gun Opinions

[J]

I would think a 308 or a 7mm-08 would both work quite well. Not a ton of data on the 7mm08, but seen some load reports at respectable velocities down to 18.5" and woukd bet it would do pretty well down to 16. Lots of data showing 18" working well on the 308.

The smaller projectile loads, 260, 6.5CM, 243, 6CM all like just a bit longer barrel before really shining. I'd take the 243 from that lot in a short bbl if I had to choose.

Hate to admit it, but I vote 308. Much more efficient than about anything out there when it comes to that bolt face.

And seeing as how you added critter killing in, that kinda sealed the deal.

After my last experience with Surgeon Rifles, I went with a Bighorn. Maybe one day Surgeon will send me the correct 223 bolt instead of the 308 bolt.

damn Hoser, I expected a different answer from you! I've seen the load data running a .243 with 75gr a max at 3000fps, no one else thinks that's pretty damn good?

Tim K, you have more to share your just holding back....

But did you find a 75g @3000 out of a 16-18" bbl? 243 likes a bit longer barrel.

There we go, a .243 vote! I have a 6.5x284, its a screamer. Have a 6mm creedmoor for my DTA, it's gtg too. I think I'm tossing the .308 and the .243 around the most, but necking down a .308 to .284 seems to make sense on paper!

18" barrel.

Impressive. What powder?

[J]

Agreed. The 284 projectile in the 308 case is a great combo on paper. For a lot of reasons.

7mm08 is nice i got to pay with a ultra lite pack one. Made on a 600 chasis. It was cool.

My first deer rifle was/is a Rem 788 in 7mm-08. I downed a lot of deer with 140 grn partitions from its 18.5" barrel. Handy little rifle/cartridge combo.

Ok, now I'm thinking of an 18" .308 set up to run the 155's, anyone running the 155's?
