What can you kill with a 6.5 PRC that you can't kill with a 6.5 CM? I am talking 300-500yds, only because the LR game always comes out.

I have been reading and researching the 6.5-280 Ackley and I keep seeing these arguments for this 6.5 over that 6.5.

I realize they both have loyal followings, but good lord, a 30-30 gets it done

Riddle me this: what can u kill with a 6.5 Creedmoor than you can’t with a time-honored and proven (think Jack O’Conner) .270 Winchester? The .270 Winchester has a slight edge over the 6.5 Creedmoor ballistically. IMO, the .270 has a huge advantage over the 6.5 as relates to effectiveness on game at longer ranges. IMAO, the 6.5 Creedmoor adherents are part of uninformed, fad-following, social-media-addicted newbies to long-range hunting

Amusing, seeing a grown man intimidated by a different cartridge and getting all defensive.
I have one of each and am quite happy with both.

Not intimidated nor defensive; just facts. But you already have a grudge against me for my views on the “vaccines”, that you cannot disprove; thus, your unfounded animosity rears its ugly head, which your juvenile emotions cannot control. I’ll break it down for you in simplistic, elementary language you MAY understand: In other words your childish nature doesn’t have the intellectual capacity to reason rationally.

Actually, I have the capacity. I reserve it for intelligent adults.

Adults that can speak child-eubonics? I can’t relate to that; my bad…

My question was specifically to the 6.5 PRC vs Creed

I don't have either, I actually have just about every caliber except 6.5 at the moment, I sold my 14lb McWhorter 6.5-280 Ackley but I am building another simply because it whips both the PRC and Creed with relative ease. Titanium and carbon this go round though.

The PRC vs Creed is much like the antivax vs vax threads, they turn volatile rather quickly. The reason I asked the question here was simply because I know enough of you guys that will speak the facts vs the feelings of the comparison.

My full custom rifle that is being built currently is a 7mm-08, should see it in a couple of weeks, so I have no skin in the game as they say.

I am also fully aware of the 270 Winchester capabilities in the right hands, I remember reading Boddington's article about how the 270 Winchester doesn't get the respect of a lot of elk hunters, he shot an elk at 437yds with a factory southpaw something or other and factory ammo, 1 shot DRT.

There are a lot of calibers, saami and wildcats that are far more capable than most people are willing to give credit to, the 25'06 #1 Stainless Laminate in my safe has proven many times over its very capable of killing big pigs and coyotes at unrealistic distances. Same with the 243, saw my cousin kill a metric ton of mule deer, two good sized elk, several speed goats and finish off a Moose our great uncle shot and the broke the bolt handle off his Weatherby Mark V 300 Weatherby, cousin earholed him at several hundred yds. He was my dad's age. my aunt was 27yrs older than my dad. Us kids watched him jump out of the station wagon we camped in when our lease was in Van Horn, Texas and shoot a good sized mule deer buck in a dead run at about 300yds, single round and rolled up like a window shade. Us boys from 9 to 16 decided that day we were not going to test him.

One thing to consider is that for a given bullet started at X FPS vs Y FPS (ie, 2 different cartridges shooting the same bullet), the velocity gap closes the further you get downrange. That is to say, the velocity head start of the PRC vs the Creed diminishes as you get downrange, though at "only" 3-500 yards this may not be relevant.

May I ask your rational here?

A properly set up 6.5 prc will be within 50-100 fps of the 6.5-280ai and a 6.5 GAP is same same though both the prc and Gap will benefit from atleast a medium length action to seat vld’s out.

I had a 24” 6.5-280 ai for a spell and it got 140’s to 3200 fps without leaning on it too very hard. My current 24” 6.5 Gap is shooting 143’s at 3145 and again I’m loading it near the top end but not pushing it too hard.

Having been down the 280ai route more then once if doing it again today I would build it off 06 brass due simply to availability of quality brass and I’m not a fan of Nosler’s soft brass or their Goatphukk of saami’ing the round shorter then every previous 280 AI causing headspace issues with previously built rifles.

I too looked at all the 6.5s and decided a 270 is same-same out to 500 yards. Beyond that, the 6.5s start to shine.

I can't answer the question, but I can say the 6.5-280AI/6.5SAUM extra velocity extends the energy on target by about 150 - 200 yards. As a hunter I like that, although I'm not crazy about the increase in recoil. I haven't looked at the numbers lately, but inside 400 - 500 yards the easy button is a 270 or a 280.

My only 6.5 is a 6.5x55 Remington 700 Classic, I'm probably not the best person to ask.

I call BS on this statement.... how about posting some ballistics charts that prove me wrong... comparable bullets, comparable ranges out to say, 700 yards, etc....

Any 6.5 case from 6.5x47 to 6.5 PRC is fine. Bullets matter more than headstamps and the Berger 140 vld is made to order for killing things. In the end, pick what you want based on your experiences, or I guess what you read.

Question was asked about 6.5s. I'd be fine with anything 6mm to 7mm personally at those ranges.

I am building a 6.5-280 Ackley for me, don't care about the Creed or PRC, but will probably build the kids a magnum contour Creed to hunt with, 8 & 12yrs old.

But when you search the web, 6.5mm anything, the time honored my 6.5mm whips your 6.5mm any day and twice on Thursday post show up. Looking at reload data, published and proprietary, the numbers don't stray to far from one another, so it was just a curiosity to know what exactly could a PRC do that the Creed couldn't do.

I am also curious what exactly this PRC clicking issue is that I read about but haven't seen it fully explained.

Thanks again

I use the 260 Remington for the 6.5 caliber or one day my old Steyr M/S in 6.5X54. I haven't seen a reason to shoot past 100 yards yet. It could happen with the corn and bean fields. But I like to slip up to powder burn ranges. Have used a black powder Old Army Ruger at that range. Enjoy your long range game, but I will enjoy sneaking up on them. Maybe there is some injun in this Euro looking 70 year old kid. Be Well, RZ.

Mule Deer did a piece a few years back that compared the .270 with a 150gr ABLR at 3000 with a 6.5CM and IIRC, a 140-ish ELD-something at 2800 or so. The .270 had less drop and drift out to 500. No doubt more energy on both ends as well. At some point past 500, the CM would overtake the Boomer round. New .270 bullets in barrels twisted for them would do better, but no matter to me, because I’d never shoot at game even that far out. The real point was, I think, that the .270, even in standard rifles can reach out there just fine, as far as most should shoot.

All the bigger case does is push the same bullet faster which means more energy and less drop per given range. On 300-500 yards it's probably irrelevant.

This for the win.

The 6.5 x 47 Lapua is Superior to both...

There’s always one in the group…. Raising hell.

When’s the last time you saw a box of 6.5x47 CoreLokts…. Sheesh

Funny you bring Boddington into this crap show. He used to think the 270 winchester was at the very bottom rung when it came to elk cartridges. As for PRC vs Creedmoor. The PRC is faster and extends the reach over the CM. However, the Creedmoor can kill further than most of us have business shooting a big game animal at. Also, you remark about the 30-30 getting it done "good lord". Yes, it can, but not at the range the 6.5 CM or PRC can. Not even close.. Is this another, I hate the 6.5 "man bun" thread?

Too funny. I’m as guilty as the next. I have a few 6.5 CM’s, a pile of 270’s as well and a single 6.5 PRC. The CM is a neat cartridge and easy to make shoot. The 270 stands on its own as a killing, hunting persons cartridge.

When I did the load work I ended with a 129 Nosler at 3200 in the PRC. Just about the same as my 270’s do with a 130. For my purposes they do the same work. I’ve got room for all of them. They are all pretty fun.

I won’t even bring up the weird 325 WSM that shoots great and is about as odd as they come.

I am building a 6.5-280 Ackley, not interested in the PRC or Creedmoor, could possibly see a 280AI in the safe at some point. Pick up the Alamo Precision Rifle 7mm-08 tomorrow after work. Bought a 6mm Creedmoor Predator from the classifieds for the kids. I have a second rifle at Alamo that should be completed in a little over a month.

I have a Winchester 670 currently chambered in 30'06, would love to use it as a donor for a 6.5-280 Ackley, but I don't know how to make it work, tried a loaded round in the Winchester from the McWhorter 6.5-280 Ackley and it would not fit.

So now the decision is, sell the 670 and find a 700 donor action or build something different with it. I really hate to sell it, the safety and trigger are exceptionally smooth.

Do they make a Wyatt style box for the model 70/670 rifles? I would really like this to be a walnut stocked blind magazine rifle just for grins, but I am not opposed to a BDL style bottom metal.
