6.5 PRC or 6 MM Creedmoor?

[Ernest T]

I wouldn’t worry about what you’re hearing man. If this just about you worrying about your 6.5CM, DON’T! Don’t chase crazy velocity and the 6.5 Creedmooor will last a whole lot more than 1000rds..
My post was poorly worded. I’m worried about barrel life in the 6mm CM, not the 6.5 CM. I used the number of shots out of the 6.5 CM as a reference point. Given the same use, I’d shoot out the barrel of the 6 mm CM in a year.

Which is why I ended up with a 6BR.

[Dave Hoback]

Yes, I agree. Just nature of the beast. You push a 6mm projectile to 3400-4000fps, and it’s going to burn barrels up faster. It’s just physics. Doesn’t matter if it’s 22, 6mm, 6.5, 7mm, 30cal or larger! Push any projectile that fast, and a barrel burning they gonna be! Likewise, the slower they travel, the more rounds can be expected through the bore before accuracy decline.

Remember it’s all relative. Driving X-bullet diameter @ y-velocity takes z-amount of powder. The more powder requires a larger case. It’s purely a velocity game. So, it’s simply deciding what you want.

I view barrels as a consumable like brass, they only last so long then get replaced, if we are looking at a 6mm that would last a few rounds and can reach a thousand yards I would look hard at the 6MMBRA. I like most of the 6mm rounds and most of the 6.5 as well. I might not be the best guy to ask though as I just ordered a 6.5 PRC this week :smile-new:

[Ernest T]

Still going back and forth. One day its the PRC, the next the Creedmoor, and then the Dasher. The fact is, it probably doesn't make any difference as I'll probably buy one, then later another. The current 6.5 CM is more than adequate out to 1200 yards, and that's the max distance at a range I can wake up and decide to go shooting at without a couple days of planning.

Here is the way i look at it. Unless you are going to go with something with less recoil for a reason, the performance difference with any of the 6mm rounds isn't really a significant difference. to me the 6mm rounds really comes down to recoil management and not performance advantage.
I have a 6.5 PRC, and just got a 28" barrel for a better mile shooting rifle. I made the choice to invest my money into a 6.5 PRC, my brother invested in a 7mm WSM with a 30" long barrel for the same purpose. It really is a tough choice between the 7mm WSM and the 6.5 PRC with (IMO) the advantage in performance to the 7mm WSM with a decent recoil penalty.

I would keep the 6.5 Creedmoor and get a 7mm PRC or 6.5 PRC for the longer range shots. I like to shoot both my 6.5 PRC and 6.5 Creedmoor and love having both. there is a definite advantage to the PRC. i am at 2840 FPS with my 6.5 Creedmoor with a 26" barrel and 140 ELD-M. with my 26" 6.5 PRC i am at 3050 with 147 ELD-M and 145 Match Burners. That is a pretty significant performance gain from the 6.5 Creedmoor.
I am hoping for 3150 with the 145 match burners or 3100 with 153 A Tips with a longer barrel, better brass, and trying out a few different powders. That should be the ticket for me.

To the OP...

You said you don't hunt and don't shoot competitively, so I'm going to throw a monkey wrench into this discussion by enlightening you to another option: a fast twist .224 caliber that soo many dismiss or overlook due to ignorance. A good fast twist .224 caliber shooting sleek high B.C. bullets will do anything a 6mm can, and often times do it better. Obviously I'm not talking about a .223 Rem based cartridge here, but something akin to the .22-250 Ackley Improved, .22 Creedmoor (basically identical to the 22-250 AI in terms of capacity and efficiency), a shortened 22-284 Win. wildcat, the 22 BR, etc. Basically something with sufficient case capacity to push those 80-90gr pills to 3200fps or better.

Just as a personal example, I've been shooting the 22-250 AI with a 26" 1-8 twist barrel since 2004. With a stout charge of H4350 propelling an 85.5gr Nosler RDF. bullet to 3,250fps @ muzzle. With a 200 yard zero I only need to dial in 6.4 mil of elevation, and while the 22 caliber bullets will be affected a bit more by wind, given the aforementioned setup with a 10mph crosswind it's still only 2.0 mils of windage. Comparing that to the 6mm Creedmoor pushing a Nosler 105gr RDF at 3050fps with the same 200yd zero, you would be looking at 6.8 mil elevation and 1.9 mil windage.

So the 22cal has a slight advantage in drop and the 6mm has a slight advantage in wind, but it's basically a wash. Both cartridges in this example use very similar charge weights of the same powders so that's pretty much a wash as well. Where the 22cal has a bit of advantage is in recoil and cost. Granted the difference in recoil isn't substantial, but it's there. On the cost side, 22cal bullets are notably cheaper than the 6mm bullets - and MUCH easier to find since everyone and their brother is currently on the 6 and 6.5mm bandwagons.

While these faster 22-caliber cartridges are often labelled as barrel burners, I've been shooting the same Douglas barrel for 18 years now and have run just over 2000 rounds through it to date. Last time I had it out and shot a group at 200, it measure just a hair over 1/2 inch, or 1/4 MOA. Don't have a pic of that specific group, but I'll include one of a similar group shot in 2018 with said rifle with 80gr Nosler CC's.

Yes I'm probably overdue for a new barrel as the bore looks like alligator skin for the first 4-5 inches at this point, but the dang thing still shoots!!

I've decided to go with the 6 mm Creedmoor. In all reality, I'll probably end up with both a year or two down the road, but the smaller caliber interests me more right now. At first, I was thinking of the Savage 110 Tactical Desert, but I've since decided to splurge a little for this gun. I've narrowed it down to a Bergara Premier Competition, Christensen MPR Competition and a Masterpiece Arms BA PMR Pro Rifle II. They're essentially the same gun, for the same price, just different flavors.

So…. 3 cartridges that all pretty much do the same thing? LOL! J/K

Seriously though, I’m so glad I don’t deal with this any longer. At one time in my younger life, I had a plethora of different calibers… I knew I wasn’t a collector & learned early on, I couldn’t afford to feed them all. I now have only a few different calibers. And 260Rem is my only long range caliber. It’s amusing though, every few years listening to people talk about the “best performing” long distance cartridges; which typically coincide with the newer cartridges released of that era.

Hey… what about the 6.8 Western? Or 277 Fury? LOL! Ooo-oo.. I know! I’m actually going to be releasing a brand new… never before done cartridge! It will use any .284” bullets, have a 28.2 degree shoulder, a neck being a little longer than standard neck, but not as long as long neck, that I will call the MID-Length Neck! And…. it will be a short magnum case to fit a Short Action. Oh, but.. it will actually perform better in a long action so the bullet can be loaded to a very long COAL like it’s supposed to. Of course, my new shoulder angle will perform MUCH better than a 30 degree shoulder. And I’m basing that entirely on nothing except my banter that forum members will repeat over & over again until it becomes fact! I will name this one the 6.98mm Gotchya! :behindsofa:

You are going to love the round. It's an easy shooting round, very enjoyable. I like it so well I had to have two rifles chambered for it, one with a 22" bbl for hunting and range, the other is a 26" for range and LR.

Nothing wrong with the 110 Tactical Desert except maybe its stock, a MDT chassis will fix that.

Let us know which rifle you finally decide on.

I'm just thinking about trying something different, but didn't want to go too big because I can't handle a heavy recoil due to a bum right shoulder. I've had three surgeries on it, between a football injury in 1977 and a motorcycle accident in 2020. The last one left me with a 5" long titanium plate, and 8 screws. I've still got a torn labrum and partially torn tendon and eschewed further repair because the doc said it was about the most painful procedure an orthopedist could inflict on a patient and at my age probably not very effective and unnecessary.

I really like the idea of the 6mm CM with its light recoil and flatter trajectory, but the short barrel life puts me off a little. On the other hand, the the 6.5 PRC also shoots a little flatter, but with the heavier bullet and larger powder charge I could reach a little longer range than I can with the 6.5 CM. I'm ringing steel with it at 950 yards, but I wonder how what the maximum range is in my hands. No hunting, no competition, just tinkering with loads, groups at 100 yards and long range plinking.

II had a friend recommend the Dasher and I need to do some research on that cartridge.

The PRS guys that ring steel at distance started with a Dasher because of it's accuracy, speed and
light recoil. It a good round. If you need a bit more, the 6gt is now the favored cartridge in that
game. Nothing wrong with the 6 Creed, but I would do Tubb's 6xc first just to tell Hornady to kiss
my ass.....

I was out at the club on Tuesday and a guy had a Masterpiece Arms in 6.5 CM. That was a beautiful gun with a very heavy barrel. The action was butter smooth and it was shooting pretty good groups. He said he's had it about 8 months and put 200 rounds through it so far. It's enticing to forget the Bergara and order the Masterpiece Arms -- they have a 10-12 week lead time right now.

If I were to spend that kind of money I'd go for something like a bighorn or bat action, krieger/bartlein barrel, and chassis/stock of choice.

Id just keep my Savage Action and put a bunch of high end components on it…. OH, wait a minute! I already DID THAT!:boxing:

Then you would spending a bit more than $2500 for a complete gun wouldn't you?

[Ernest T]

I looked at that option and after buying a savage rifle, putting a different trigger, stock and bolt on it, I'd have an expensive Savage Rifle.

[charlie b]

Maybe $3000. At that point you are looking for the best. I'd not settle for anything less than one of the really good barrel makers.

If you don't want the best, then a simple Savage or Rem action, Krieger barrel and Boyd's stock (or less expensive chassis) will get you a bit further than most of the other ~$2000 guns.

Keep in mind that if you are not capable of shooting in the 1's or 2's then spending that kind of money is counter productive. I am not that capable so I stick with the less expensive options.
