6mm Creed in Long Action

[KTWebb]

I have an Origin Long Action I originally planned to use for a rifle, but recently got the idea to try and use it for a SA build (temporarily for a few years). The thought is to build a kids/family rifle for deer/fun (low recoil). 6mm creedmoor is on my mind.

Could I build it out using the Accurate Mag 308 Long Action Mag?
Anybody have experience with a similar SA built on a LA?
Anyone have experience with the Accurate Mag 308 LA mag?

Assuming you can get it to feed reliably the only disadvantage is the extra weight (which is an advantage if it's not a hunting rifle or being used in a weight limited competition). Feeding issues are pretty common with SA cartridges in LA receivers, but can generally be resolved with some magazine tuning.

Depending on your goals 243 or 243 ai might be worth a look. The advantage of Creedmoor cartridges is the ability to run long, high BC bullets in a short action. With a long action and an appropriate barrel twist you could do the same with 243. You'd gain a little extra case capacity which you could take advantage of with hand loads, but it'll be even more of a barrel burner than 6 Creed.

Not concerned with the weight difference . It would be a short (18-20") gun. 243 has crossed my mind, and is very common where I am at. I just liked the 6mm creed cause it's a different flavor than I'm used to seeing.

What would cause a 243 to load in a LA better than the 6 creed? Simply the slightly longer case body?

for a kids/ family/ fun rifle I'd just go buy a Ruger American in 6 creed and never look back.

Great option, and I have considered that! Ruger American or Savage 110, cut/threaded, and could dress it up if you wanted to.

It might feed a little bit better since if you load long, but mostly you'll be able to get a bit more velocity from the extra case capacity (assuming you hand load). You can load it longer than SAAMI spec to run long bullets no problem. If/when you switch to a short action you'd probably want to switch to 6 Creed so you can still run long bullets, which might leave you with some unused dies and a pile of brass.

None of that matters if you're shooting factory ammo, in which case Creed is the way to go.

I hand load, and would likely shoot a mixture of factory and hand loaded ammo.
