    SAUM requires either a WSM action or feed rail modifications. PRC works in a magnum action with no modifications.

    Is the PRC really all that different from the SAUM?

    Ballistically I'm guessing they're basically identical twins, but even dimensionally they appear to be nearly the same.

    I think it's important for you guys to understand what is being done here, and what was done with the 6.5 Creedmoor is a perfect illustration.

    The competition PRS Shooters put the 6.5 mm cartridges back in the game, using several wild cats. Hornady developed a cartridge for which they could load accurate ammunition in a desired caliber, overcoming the objections of the non-reloading crowd. By developing a cartridge they were able to spec a chamber, enabling them to overcome throat length and bullet style issues. By defining a new cartridge and designing a chamber for their bullets they were able to easily load accurate, repeatable factory ammunition for their new cartridge.

    They did enough testing to make sure that it worked, a rarity in this business. Combine this with a very intensive marketing campaign on shooting sites, especially snipers hide, and the effort succeeded. Now they intend to make everybody sell their 6.5 Creedmoor rifles and by 6.5 PRC.

    Time will tell if they are able to pull it off again. But the precedent is established. They will sponsor top-level Shooters in PRS who will win matches with the cartridge and the rifles. And soon it will be raining used 6.5 Creedmoor rifles even harder than it is right now, as many have already swapped for the 6 Creedmoor.

    And so we will all watch them learn again the lessons of overbore cartridges and barrel life.

    Like everything Remington has ever done with cartridges in its entire miserable existence. I will NEVER forgive them for the 244 Remington:mad:...

    The 6.5 PRC, I think, just fixes the rebated rim and offers more short action compatibility than the 6.5x284 which is too big for a short action and, as mentioned, can be finicky in feeding.

    Nothing. Difference is the PRC has one of the largest manufacturers backing it up and breathing life into it.

    I think after doing some research that it's closer to the 6.5-284 than the short Magnums. Leaning toward one at this point just because it can be built on a SA without neck sizing up or down and brass is available.

    The PRS has three Bolt Gun Divisions – Open, Tactical, and Production. This does not include the gas gun division, obviously. I think you're about a year behind what the actual cartridges are for PRS, at least in the professional divisions. Currently, the short 6mm BR variations are winning and changing the hearts and minds of men in the Open and Tactical Divisions. In the Production division though, in an attempt to cater to the beginning shooter, with the emphasis on price ceiling and availability of commercial ammunition, the Ruger RPR rifles and other similar versions from other manufacturers in 6.5 Creedmoor and the 6mm Creedmoor dominate.

    PRS has a velocity ceiling, something which pushed us towards H-1000 in the original 6.5 GAP 4S. Ostensibly, this 6.5 RSAUM when loaded with the 140 gr. Berger VLDs over 61 grains of H-1000 yielded the proper velocity in order to safely make the cut for competitions. This is, as most know, holding the 6.5 RSAUM back, maybe not substantially but holding it back none the less. But there was no need for more velocity as it was a rules violation. So any cartridge with nearly the same capacity and performance will be less than suitable for the current levels of PRS competitions. In essence, the 6.5 PRC will not run the Creedmoors off let alone the 6mm BR variants in competition. Smaller capacity cartridges, smaller, sleeker bullets with lower recoil are edging out the bigger, higher performance (velocity potential) cartridges. This is no different from what is taking place in 1,000 yard benchrest where the 6mmBR cartridges are winning over the magnum cartridges and WSM variants when the wind gods keep it under a dull roar!:eek:;)

    This 6.5 PRC is an excellent exercise in managed development and marketing by Hornady. It has the potential for being a superb hunting cartridge as well as F-class competitor. Testing is underway to see what results from using lighter weight Match solids and some of the hunting style solids in this cartridge. So far, magazine feeding is right on the mark. ;)

    Another thing that is appealing about the 6.5 PRC from a gunsmiths perspective is that because there is factory ammo...it is basically impossible to mess up. My gunsmith can build his chambers around the factory ammo, give the rifle to a customer, and get him a box of ammo and say "Go shoot this" with little to no worry.

    Some people are not responsible enough to reload, and some people do not follow instructions very well. I have seen guys get custom Mausers, and they are told specifically...do not shoot Military Surplus ammo through this because the chamber has a shorter throat for good hunting ammo...and the first thing they do is shoot laquered cased Czech ammo through it and the gun locks up.

    You can say that again!!!!!

    I really try and avoid going to public ranges. I cannot turn a blind eye when someone is doing something wrong. One for safety reasons but you never know how they are going to react when you in all honesty are trying to help. Sometimes they freak out on ya!

    Last time at the public range I seen 3 guys trying to get a M1 Garand to shoot. Yes not one but three! My son looked over at me and said, “Dad you really need to go over there!”. I said o.k. So I pointed out the workings on the M1 etc...and care and tips for it and got them up and running.

    When we we’re leaving the range one guy said,” I seen your one ammo box was marked 6.5CM?” I said yes. Why? Well we have a 6.5CM but the ammo won’t chamber. So I said let me see your gun and ammo. OH MY GOD! They bought 6.5PRC ammo and they we’re trying to get it to chamber in a Ruger Precision Rifle in 6.5CM. I nicely said that’s not 6.5CM ammo. Showed them the difference in the ammo and gave them a box of 6.5CM ammo I had on me.

    A lot has to do with marketing... First off...a 260 Ackley will get you 2950 ish with a 140 bullet. The 6.5 PRC is shooting the same bullet at the same velocity in Hornady factory ammo. I'm guessing they are limiting the velocity to 2950 because they are keeping within a certain pressure limit. Look at the 6.5 Creedmoor. What is it really doing that a 260 Rem, 6.5x47, 6.5 slr, 260 Ackley , 6.5/250 AI, 6.5x55 (ya I get this is a Long action round essentially), and other 6.5 wildcats based off of a 47-51mm case? Marketing was phenomenal and the 6.5 CM was touted as the greatest round invented in the last century! It is a great round but if any of the other rounds mentioned were pushed hard by ammo/brass makers, top shooters, and gun writers...I'd bet they would be just as popular..Same applies to the 6mm CM... better than 6x47 Lapua or 6xc or 6 SM, 6 SLR, 6 Competition match or even 243?
