6 Creed is the easy route to do-all. Great factory ammo in 108's ELD-M or 80 ELD-VT. Can shoot 20"-24" barrel out as far as you want flat with very little recoil (especially suppressed) all in a .308 bolt face.

I fully intended to do a 6x284....but after seeing the results from this last xc I spun up, the juice wasn't worth the squeeze. The xc gets 3100 with that long 106 tap and shoots it VERY well. I can't give up 1k shots of barrel life and eat the extra 10-15 grs for another 1-200fps.

Yesterday I cold bored a 10" @ 1485 with the xc. That's plenty for me.

What kind of velocities are you seeing with that cartridge?
Which cartridge are you asking about my 6-284 or 6mm Creedmoor?

My 6-284 has a Lilja 12tw barrel finished at 26 and I'm shooting 75gr Vmax right at 3700 using H4350. I'm sure I could switch to RL26 and shoot the same bullet up around 3800-3900 but the load I have for it with H4350 shoots crazy good as well as I have a couple hundred loaded up with that load to burn through first. Also, this is NOT a fur friendly bullet as it almost always leaves them with rather big holes.

My 6 CM has a 9tw 20in Proof CF barrel and I've been shooting 70gr Nosler BT's w/RL16. It's not super speedy only around 3400 but it shoots extremely well with that load.

I sorry I meant the 6-284. That’s impressive. Should be able to push the coppers fast enough.

How’s brass situation for the 6-284?

I have a tikka donor rifle that I’m struggling to decide what to rechamber/rebarrel it in. It’s currently a brand new 243. Also I’m not sure what I want this rifle to do.

I was looking through Shootingbot - looks like only Nosler 6.5-284 and Peterson 284 are readily available new. On Gun Broker there’s a good supply of new old Hornady and new old Winchester.

Thank you very helpful. The regular 284win has me intrigued as well.

Assumed you meant the 6-284 but well we all know what happens when we assume.

If I could only keep one rifle that's in my safe it would be my 6-284 so it's pretty safe to say I am a huge fan. Actually, I'm a fan of just about anything based off of the 284 case.

Your Tikka should work pretty well as a donor and I'd think a smith could rechamber that 243 barrel to 6-284 pretty easily if you wanted to repurpose that factory barrel. Depending on what bullet/s you plan to us the only thing you may have to do is put a longer bolt stop in and get a 270Win or 30-06 magazine so you'd have plenty of length. I'm sure any good gunsmith would know which reamer to use but there's lots of different 6-284 reamers out there. When I was first talking to the smith that built mine about building me a 6-284 one of the first things he asked me was if I was using a short or long action because he had different freebore lengths depending on what length action people were using so if you have plenty of length you wouldn't want to use a reamer that's for a short action.

For dies you can get specific 6-284 dies or you can use a bushing 6.5-284 die with the correct size bushing. I use Redding dies for mine. I neck down 6.5-284 brass to 6-284 in one pass it's easy peasy.

If you're looking for brass I have a couple hundred pieces of new unfired Norma 6.5-284 brass I'd sell someone if they're interested.
