Barrel length

[twarren]

Would an 18" barrel work OK for a 7 SAum WITH 180GR. BULLETS

Short answer is NO - if you want magnum performance.

For this cartridge to perform at its maximum potential, slow burning powders are needed which require barrel lengths of 24 to 26" to burn properly. With an 18" barrel, you're tossing a lot of powder down the toilet.

If you want a short barrel 7mm hunting rifle, the 7mm -08 might be ideal.

Will it work? Yes, would it be ideal, no.
What are you wanting the 7 saum for?

Kinda like hooking a race horse to a plow: it will work but your limiting it’s speed and what it was built for

Look at the Long Range Hunting site at the specialty pistol section, they run all kinds of magnums with~14 to 16 inch barrels.

Probably result in an awesome muzzle blast using slow burning magnum powders.

Short barrels are going to have lots of muzzle blast. They're loud even in .243. If I was going to go with a short barrel I'd probably just go with a 7-08.

Shoot one in low light and watch 18" flames.

I built a 300 WSM with a 20” barrel. I say don’t do it, my 300 WSM is basically a 308.
