What cal rifle should I go with.

I'm thinking of buying a new bolt gun ./ maybe ar 10 . For precision shooting. I have 3000 copper jacketed bullts for 6mm already. And a couple hundred 6.5. So I was looking g at 6mm creedmoor or 6.5 Creedmoor.

I will hunt with this new rifle and target shoot.

Let me here ur advice. I do not want to do a lot of brass forming

The bullets match bullets or hunting bullets? What weight? Having 3,000 of 'em would lean me a long way towards the 6mm though.
Hunting what? Competitive target shooting or just because it's fun?
What's your budget like? Suspect a 6mm will be a totally cu$tom rifle. AR-10 or not. A 6.5 you can buy off-the-rack from Ruger, et al.
The 6mm Creedmoor is a twin of the .243 Win. About the same velocities but using a longer barrel. Midway has Hornady brass on sale right now at $34.99 per 50. ($33.99 per 50 for the 6.5. On back order, of course.) So at least you can buy the 6mm ready to load.

OK the weights go from 70 to 100 grain every make for spritzer to be hp ... deer and hogs mostly so coyote farthest shot 500 yard maybe 600. Might push it out to 1000.

So 6mm creedmoor is the same as 243 win.
What about 6br? Vs 6.5 Creedmore. So price on ammo is not bad. So not sure. I read that most comprehensive. Shooters are useing 6mm creedmoor. I'm just trying to get advice from people who shoot every day. Not take magzine or some one paided to right good reports.

Don't want to spend more than 1500 on rifle.

I would tend to think 6.5 if you are planning to hunt with it as the caliber will handle a little heavier bullets than the 6mm if such is needed. I have a couple bolt guns in the 6.5 Creedmore and have pretty much settled on shooting 123 gr. Hornady SST's, but they both group well with 140's also.

Both the 6 & 6.5 CM are extremely accurate and both will shoot farther then the shooter can see.

If you hunt up too deer size animals, the 6 mm will work find. If you want to move up to elk, I'd go the 6.5 CM route.

Finding a rifle in 6 CM will be more difficult the finding one in 6.5.

"...6mm creedmoor is the same as 243 win..." Ballistically they're very close.
6mm BR is based on the .308 x 1 1/2. Different thing altogether. I believe that would be a 'Make' thing. Way more than just forming. Factory come$ from Norma or Lapua. Cost you an organ that stuff. Lapua runs $110.99 per 50 from Midway. $105.99ish from Graf's. Basically a buck, each, for brass.

Forget '500 yard maybe 600 yards' shots with any 6mm. Not enough energy past 300 and they drop like bricks between 300 and 400.

I'm not buying that one bit. Depending on bullet the 243 remains super sonic beyond 1400 yards.

You pick the right bullet, you're not limited to short range. For example, my wife shoots 87 Berger's in her 243. According to the Berger engs. their bullets need to have a remaining velocity on target of 1800 fps to work.

In my wife's load, that's 800 yards, well beyond the 400-500 yards.

I've seen too many good 1000 yard scores with 243s to say they aren't a long range round.

That same load drops 262 inches at 1000 yards, my target 308 drops 284, both with a 100 yard zero.

PRS is a totally different animal than high power, then DMR, than informal plinking...etc.

I am a huge fan of the .243 Winchester and use it for hunting, PRS and F-Class...granted in 3 different rifles. That said, I am not sure a 6mm is the best choice for a newer person exploring precision shooting in its various forms. While I have a small following of people who have bought RPRs in .243Win, it is a specialized load and rifle that make for a great marriage, and you are handloading it. I would be surprised if the 6mm bullets you have are decent for precision shooting. Made a 1007 yard hit on my first stage of my first PRS match...so yes, Kraig is right, the 6mms are plenty.

The 6.5s (6.5CM or .260Rem) you can go buy excellent factory ammo, but not quite as much hunting ammo. It is nice to be able to buy a box of factory fodder to make sure it is you jerking the trigger and not your load development.

Barrel twist is important, as is a decent trigger and solid stock.

"...the 243 remains super sonic...good 1000 yard scores..." And? Energy is what matters for hunting, not velocity.

We are in the "Competition Shooting" forum, so scores ARE what matters, not energy. Context is important.

I love my 6.5 cm.

And I agree with those saying a 6mm can't do long range. At the local shoots, guys get 1/4 or less moa out of 6mm br's. They take like 24 grains powder. But accrue as hell

2016 NRS Long Range Championship at Camp Perry won by John Whidden using a .243. Read about it at accurateshooter.com

With 3000 6mm bullets on-hand it will take a while to shoot all the ammo you'll make. At least one barrel will be shot out regardless of which flavor 6mm you go with. Then you could continue with 6mm or rebarrel to 6.5 (choices there also) and keep shooting the new reload from your 6.5 stash.

I Shoot 6.5 Creedmoor from the bench, no hunting. If I had your bullet stash then I would go for .243 Winchester and work up load for whatever distance I choose to shoot. Brass is readily available, many rifle choices and cost per round would be under 20 cents once brass is on-hand. Depending on how hot you load, that should get you through 2 barrels and then start on the 6.5 during the 2nd rebarrel.
