Tell Mr About The 6.5 PRC Please

Your saying you keep the 6.5 CM because it was more accurate then the 6.5 PRC Right ? Well the rifle controls the accuracy! NOT the Cartridge ! So would you have keep the 6.5 PRC if it shot more accurate ? RJ

WRONG!

IF that were true then cases like the 6PPC and 6BR wouldn't absolutely dominate Benchrest competition. There are most definitely features of the cartridge case that increase accuracy.

The 65CR has a very long neck and a relatively flat shoulder angle. Those two things increase accuracy over a shorter neck and more sloped shoulder. The shape and length of the powder column also contribute to accuracy. Typically shorter, wider powder column is more accurate than a long, thin one.

All good stuff. The thing is Jerry, your precision expectations are higher than most shooters, and your shooting volume is probably higher too. I think the biggest challenge for most long range shooters that actually understand the math is spotting their misses. I’m not sure if a downrange camera, or high end spotter, or bigger bullet is cheaper in the long run. Ballistics don’t matter if you can’t see where it hits.

I took a 243 out to 2000 yds with 95gr Scenar bullets. Spotting misses was always an issue. But then the rifle didn't kick the crap out of me every time I pulled the trigger. ;)

I suspect the majority of people in conversations like this have never shot a target beyond 500 yds, which makes the discussion over this gigantic cartridge or that gigantic cartridge a little silly. It's not the tool, it's what you can do with it. I know Jerry took a puny little 223 out to close to a mile, which is the ultimate in long range marksmanship IMO.
 
I am on my 3rd 6.5 PRC barrel. I tried it for long range target, it works.
Its a fantastic hunting cartridge - quick, flat, and good energy with 140 thru 156. I took two moose & 4 deer, all one shot.
It is hard on barrels if you load to its potential. Mine were a byotch with carbon/copper fouling and ring.

I have, for ####s&giggles, also loaded 6.5cm somewhat hot with R26 143eldx to same velocity as 6.5prc factory 143eldx.
Despite what you read, IMHO, r26 is prob the best powder for peak performance in the 6.5cm

But i will second Wallz comments - i do now use the 6.5cm for long range targets/practise, you get great performance for much less $$$, and much longer barrel life. Important to me these days due to the cost of all these things.

I shoot in MOA. In my rifles, at 1000yds,
6.5 PRC 140 SpeerImpact is 24.0 moa, 10kmh crosswind 4.5 moa...57.2gr powder
6.5 cm with 140 BergHyb is 25.25 moa, 10kmh crosswind 4 moa....41.9gr powder
6mmBR with 105 BergHyb is 28 moa, 10kmh crosswind 5 moa....30.2gr powder

These days, if i was to pick one to shoot wee-bitty groups 100-1000, 4 of 5 times its the 6mmBR - unless very windy or bored, then 6.5cm

Maybe SBR, but neither of those cartridges dominate the F/O World however, which is shot from 300 meters to 1,000 meters.
I shoot a 6mmBR pretty regularly at 1K, and a .223 for a TR rifle as well, and although there are instances where the smaller calibers win in TR and F/TR - Nicole Rossignol comes to mind, on the whole they do not dominate those disciplines.

6mmCM will shine against the 6.5CM from 100 to 1000m.
You will see people claim 6.5CM can throw a 140gr VLD at 3000fps, take that with a grain of salt, gotta go way over pressure to get near that, 2750 give or take is realistic.
The 6.5PRC can safely throw them near 3200fps.
Is it the bomb for long range? Depends I guess on your goals, recoil ain't much, it's nice to shoot.
300Win is in the thread, my buddy shoots that for 1000m+, it's braked, and he's gone through many of them from factory Sendero's to full custom builds. Heavy 30cal bullets shoot well, they also have a #### load of energy if you actually want to shoot something not paper. I've never been able to group #### like he does with anything I have at the 700+1000 range,.come close sometimes with my 7mm Rem and 162ELDM at 3000fps, nothing to be embarrassed about at all, but holy hell, my 7mm don't hit the plates like a 300win with 212's or heavier, big difference down range.
Now... regardless, I still don't want a 300win, or 300PRC, too much recoil, too much cost per round, it's paper or steel, it doesn't care lol
 
I have a 6mm Creedmoor custom build by Insite Arms that I just acquired from the estate of a dearly departed friend and am just starting to work with it, his reloads while relatively mild are very accurate and it will shoot tiny little bug holes when I do my job, I have not yet taken it out past 1100 yards. I also have a couple Christensen arms mesa long range rifles in 6.5 PRC and 7mm PRC both wear Nightforce NX8 scopes and both will constantly ring steel way way out there, the 6.5 PRC I have had for 3 years now and have some good loads worked up for it, the 7 PRC on the other hand is new and I'm just getting started on the reloading process, the factory ammo in 175 ELDX and 180 ELDM from Hornady shoots very good so far and I have a good supply of it so will continue to shoot it and farm the brass for load development.

Nice ! and now that there is both ADG and PETERSON brass avail for the 7 PRC ! RJ

You’re WRONG AGAIN !

You can take both those 6 PPC and 6 BR and any other accurate cartridges and if they have a ####t* barrel there not gonna shoot accurate !

My F Class 284 win will some times shoot 1/4 Moa but it’s also a very Heavy barreled bench rifle - My M7 Custom 284 Win LW mountain rifle is generally 1 MOA

Point is you need a VERY ACCURATE rifle for any cartridge to shoot good ! RJ

Had a Weatherby Vanguard in 6.5prc and was getting about 1.5 inch groups.

Have Winchester XPR in 6.5 creedmoor and I get sub moa groups.

Sold the prc and still have the cm

Just because two different rifles in different cartridges had different precision capabilities, this doesn't mean one cartridge is more precise than the other.

It really depends on the quality of the barrel, quality of the chamber, the quality of the ammo, and how that ammo interacts with the specific chamber its shot through.

This is in no way evidence to suggest that the 6.5 Creedmoor is more accurate than 6.5 PRC.
 
Finding a Weatherby Vanguard that can't beat 1.5 MOA with certain ammo sounds in no way remarkable. Even the 6.5 CM ones trust me lol

All I'm saying is that I had two rifles chambered in 6.5, one in prc and the other is a Creedmoor.

I don't need two rifles in 6.5 so I kept the most accurate one and sold the other.

In no way was I saying anything bad about the prc or the Weatherby it's just that I kept the cm because it was more accurate.

What was the point of your original post then? You told an irrelevant story that provided nothing to the op considering the 6.5 PRC. Then got mad when you got called out. Cool story though, LoL.
 
I purchased a Christensen Traverse in 6.5PRC from Prophet River, and while waiting for dies, and brass, I tried a box of Hornady Precision Hunter loads. The first three groups averaged under 3/8" with the best three shot group being .200". My handloads gained 80fps, and three shot groups are still averaging under 3/8".

That all depends.

There's no one hard limit.

It depends on environmental conditions, conditions of the area you are shooting in and the ability to read/spot impacts, energy required at impact, etc.

The 6.5 PRC is a ginned up 6.5 Creedmoor. It can do what the 6.5 Creedmoor can do, but a little better (and worse in some categories). A big limitation of 6.5mm projectiles is going to be the ability to spot splash in certain conditions. You can launch a 6.5mm projectile to 2,500+ yards - but are you going to be able to spot the impact?

For a good portion of conditions, you can take a 6.5 PRC to 1,500+ yards/meters. If you're goal is to do 1,500-2,000 regularly in a variety of conditions, I think something like a .300PRC or .300NM (or even a 7mm cartridge) would be better.

But it all depends on a variety of factors.

As I said earlier, you are asking a BULLET question... just follow my advice, plug in the numbers, see the downrange results, then research the bullet(s) desired.... and under what conditions they will fly.

FYI, I have shot a 6.5 Mystic (my version of the 260AI) to a GPS ranged 2340yds a very long time back... far enough back, Berger was a new company. Every bullet I could have used would be subsonic... some made the trip, others didn't.

when you figure out this question, you will have your answer

Jerry

PS, in case you really don't want to understand why all the above matters, simple answer... for every bullet from a CM vs a PRC, you will be in the same spot ball park 150 to 225 yrds further... some bullets, this will narrow. Others, this will extend but there is no magic that will ever stop this from happening... and of course, this will apply to any cal, cartridge and bullets. How far can it go? Ask the bullet.
