What makes the 6.5 PRC special?

[therifleman556]

300 Ultra Mag? 416 Rem Mag? 35 Remington? Not being a smart ***, but I think the Ultra Mag qualifies as a success. 35 would to even if it's not hugely popular within this community. If the 416 was not a Remington design someone correct me.

Nothing!

300 ultramag definitely a success. I own a 35 Remington and it's pretty popular, but the only ammo ever available is either the Remington 150 or 200 grain corelokts and if you're lucky the occasional box of the Hornady leverevolution ammo. Is the 35 Rem popular? No doubt. Is it a success? I wouldn't say so. I've been stuck shooting the same Rem ammo for 20 years now.

The real hold-back on the Remington 260 has been Remington's crappy brass. I think Lupua or Norma is offering high quality 260 brass which is no suprise since they have offered high end 308 Win brass and 243 Win brass for some time. The cost is so high though that it turns people off since the point of the 260 is great ballistics on the cheap. Hornady brass for the 6.5 Creedmore is not the best brass on Earth but it is decent, price is decent when compared to Remington 260 brass. Remingtons primer pockets are lose the neck varies an insane amount and case weights vary a lot too.

How many non-Remington rifle companies are chambering 300RUM's these days?
There are some, but nothing like how many offer the 300WM. This is how commercial success is achieved, when other brands willingly sell THEIR rifles chambered in OTHERS cartridges.
The 7mmRUM, 338RUM and 375RUM are not doing well, neither are the SAUM's
The 416 Remington was a wildcat in it's own right, just as the 7STW was. Layne Simpson took care of all that.
I like Remington, don't get me wrong, it's just that they don't seem to be able to sell their products very well or fudge something that makes it fail.
The 7WSM is on the brink of obsolescence too, so it doesn't just happen to Remington.
Look at other failed cases, 225Win, 284Win, 32Special and 375 Win (until a rifle comeback brought the cartridge with it).
All new cartridges come with truckloads of hype, once the hype is gone, what are you left with? Either a success or a failure. Simple economics.

Cheers.

Throat length and design play a significant role in how it wears and what and how you load the cartridge. A 264WM SAAMI spec reamer has a zero leade, the entire portion with no rifling is .060" long, this was due to the original dual diameter bullet they used to bring pressure down.

There are a lot of cartridges with this style throat. Did they all use dual diameter bullets?

At the end of the day it's a 6.5-284 that fits in a short action, or a 6.5 rem mag/slightly faster 260 ackley you can buy loaded ammo for if you need/want to. If those things interest you it's a pretty sweet deal, especially if you just hold your horses a minute for good brass.

If those differences don't matter to you then you are likely either satisfied with a 260/CM/47 or you're building a 6.5SS and calling it a day since it's the baddest anyway.

^^^This....
What Hornady did was look at the 6.5mm world, and noticed that there wasn't a really good SAAMI cartridge that let you get 3,000 fps from a short action.

Sure, there were others that did that, but there was always some undesirable aspect. There was a belt on the case, or there was no standard SAAMI spec, or there wasn't good brass or ammo availability, or there were throating issues and OAL issues.

What Hornady did was to take a fresh look at the problem. They put the work in before they submitted to SAAMI to get it right. The 6.5 PRC is basically an improved (conceptually) and standardized 6.5x284 that anyone should be able to go into a store and buy match grade rifle and ammo for.

The exact same thing can be said of the 300 PRC....Hornady split the difference between the 300 Win and the 300 Weatherby and applied the same methods that were applied to the 6.5CM and the 6.5 PRC. It is a modern, beltless, efficient case that is meant to update a niche that was occupied by legacy cartridges that were long in the tooth.

if Hornady really wanted to be on the cutting edge and innovative they would have looked closer at their own 6.5 creed or the Sherman short mags for body/neck location and body tpi so that the long / high bc bullets are not jammed into the powder column. instead they did a necked down retread of the rcm case

What would you change to make it better?

think fat creedmore like Sherman sst.
I already entered the 6.5 and 300 prc in my quick design using the saami approved drawings then imported into quick load you will loose very little case capacity but you will shorten the oal and increase performance. one thing about the 6.5 creed is the case design is better

Of course they didn't.
That's up to the designer and their BELIEFS.

What is your point?

Cheers.

I don't have a "point" but I am wondering if what you said is correct.

I would like to see your drawing, is that possible?

Why would I be incorrect?
It is well documented on the design and bullets used by Winchester when the 264WM was brought out in 1958.
You can do your own research and disprove me if you wish.

The propellents used at the time had a tendency to raise pressures faster than velocity, this must be why they chose a dual diameter bullet with a narrow full diameter "driving band".
Funny how todays bullets don't feature this aspect in design.

Cheers.
