AMAX 20" Krieger Bolt = 2,850 FPS. 155gr. AMAX Seems pretty accurate to me. I ended up chopping the 6.5 CM gas gun barrel down to 22", velocity loss is only 35FPS down to 2615 FPS. I am sorry my data experience doesn't mirror yours. I have never been able to get a gas gun anywhere near as fast as a bolt gun, pressure signs and accuracy deterioration always come about 200 FPS sooner. I ended up selling all of them, except the 6.5 CM gas gun, but I am really tempted to sell that too, as it's just too heavy. IF I could only have one rifle. It would be a 6.5 CM or .260 gas gun. Thing is the more I keep playing with stuff, and running the numbers, the more I think the gas gun move is: 6.5 Grendel 16" with a 1-8 type optic. There's so much to be said for guns that are easy and FUN to shoot. Large frame ARs are neither. Your data appears limited and doesn’t mirror many others that have shared their experiences, hence the skepticism. |

The 6.5mm SAUM 4S vs the .300 WSM, at long range:
On Page 1, I've listed 60-some sources for today's AR-10's. Among those, there are about a half dozen that chamber the .300 Winchester Short Magnum --- a half step, build wise, to a 6.5mm SAUM 4S AR-10. On Page 2, 6.5mm SAUM 4S developer, George Gardner, is shown with his 1268-yard-shot antelope (6.5 SAUM 4S used, in this case). The following down-range ballistics chart compares the 6.5mm SAUM 4S - 147-grain ELD-M (BC - 0.697) load, 3091 fps Muzzle Velocity (A), vs the .300 Winchester Short Magnum - 200-grain ELD-X (BC - 0.597) load, 2820 fps Muzzle Velocity (B), at 1268 yards (dialing-in a 10 mph crosswind, at sea level) --- 
And, in addition to the Drop and Wind Drift advantages of the 6.5mm SAUM 4S, there's the advantage of reduced recoil, as well --- 
. . . . . . . . . . . . Then, there's the 1376-yard-shot bull elk (7mm Remington Magnum used, in this case) < http://youtu.be/eIn1G8BeUuc > And, the 6.5mm SAUM 4S load, detailed above (A), vs the cartridge used in the bull elk shot: 7mm Remington Magnum, dialing-in the 162-grain ELD-X (BC - 0.631) load, 2940 fps Muzzle Velocity (B), at 1376 yards --- 
Bottom Line: The 6.5mm SAUM 4S is an excellent choice for long range. |

boltcatch,
I think it's fair to state that Prime Ammunition, keen to recognize the special attributes of the 6.5mm SAUM 4S cartridge, also saw the need for precision factory-loaded ammunition --- for many, a welcome new chapter in the ongoing 6.5mm SAUM 4S saga. Stay tuned. |

Rerun the number with a 180 ELD for the 7 mag. 
The 6.5 SAUM is a wicked long range round, but it only compounds the biggest problem of large frame ARs. They are just too heavy to carry around. This cartridge must have a 24” barrel minimum, preferably 26”. I would personally want a 28”. Meanwhile, the 6.5 Timberwolf offers 6.5 CM performance and will fit in a small frame AR. The 6.5 Timberwolf solves a massive problem. The 6.5 SAUM makes said problem even bigger. With that said I would love one in a bolt gun. |

Scotts556 on the news that Prime Ammunition has added the 6.5mm SAUM 4S to their line of precision ammunition --- using Norma brass:
I confess that I took the suggestion , "Now, if only we can get a Factory rifle builder to build a factory 6.5 SAUM.", literally. And, in that I prefer a rifle design that loads itself, if follows that my efforts have focused on today's AR-10 manufacturers. And, then there's the bolt-gunners position, as stated by nick1983: 
Overall, I think it's fair to state that we agree that factory-loaded 6.5mm SAUM 4S ammunition, using Norma Brass, is too much of a good thing. My suggestion: Get involved. Bolt-gunners, gas-gunners, contact the arms manufacturer(s) of your choice, and make the case for the 6.5mm SAUM 4S. It's been my experience, over the years, that they appreciate our input. |

I'm just getting my feet wet here, but wouldn't a 7 SAUM variant, 7 GAP SAUM for example throwing 175's or 180's (.689/.796 BC's) be a nice balance/do all gun. Those BC's are higher than a lot of the 6.5 ones I'm seeing.
probably a bit more velocity than a 6.5 CM, but still under 3K. A bit more bullet width for big game, better barrel life than a 6.5, while MAYBE still fitting into an AR-10 mag with a little cartridge neck reshaping and the magazine windowing mentioned previously. the 200 grain 30 cal bullets are too long to even dream of, but could this work with 7mm? I'm a grendel fan, and the cartridge I mentioned above seems like the grendel formula for an AR-10. School me. The main obstacle to overcome is MAX COL while still maintaining enough powder capacity to push those 1.567" 175 bullets. |

The main obstacle to overcome is MAX COL while still maintaining enough powder capacity to push those 1.567" 175 bullets. In 7-08, with 180gr. ELDs even with AI mags, the COAL is too long to get close to max loads, with most powders. With SR25 pattern mags in a large frame AR, the COAL is significantly shorter. It's a good idea in theory, but basically everything in 7mm, with the new, longer bullets needs to be in a long action with a long throat. The narrower the bullet diameter, the easier it is to get into a shorter COAL. 6.5mm is about as wide as you can go in the large frame AR. You could open up a whole new universe even in the short frame AR, if only someone would make the mag well a few millimeters longer. |

I sent Prime an email. I think I found something close to what I'm looking for in the 7 SST based an the SAUM case as I previously discussed.
https://shermanwildcatcartridges.com/7-sst COAL with 160's might be accptable, 175's or 180's might be VERY close. an interesting development to be sure. Now back to the GAP Saum as I have no intentions of thread-jacking. |

Yeah that's pretty messed up.
RUAG would probably lose in the end, given the emails that have been released regarding their legal people reviewing contract revisions and going through various draft stages to a final approved version, plus PRIME's release of their banking records. But the problem is that fighting takes money; being right doesn't mean you can afford to duke it out in court. I really hope they come out of this OK. |

Got an email the other day (newsletter) that PRIME has sorted out their issues with RUAG, and they'll be doing business with each other again in some manner.
They've also already been taking pre-orders on new US made stuff, so they're not dependent on RUAG anyways at this point. |

The popular 6.5mm Creedmoor (left) and its big brother, the 6.5mm SAUM 4S, cover a wide range of use for sporting-tactical missions. And, though both are designed to work in short-action magazines, the latter offers shooters some 35% more energy at the muzzle --- and almost 49% more, at extended ranges, such as the 1268-yard one-shot Antelope kill by 6.5mm SAUM 4S Developer, George Gardner (see recent Post).

So, that is a no.
And yet you are 200% convinced that the 6.5 SAUM will be the answer to everyones prayers even though most people that have played with the caliber are not using it anymore... And you want all these companies to build these rifles that only one small company "might" one day make factory ammo for. You should order a Kreiger or Bartlein barrel, have a gunsmith chamber it up for you, reload some ammo, and then show everyone how kick ass it actually is. |

Sky-pup....maybe you could do the work, since you’re pushing for it. While it’s a capable cartridge, there’s not a lot of people with rifles chambered for it as there were a few years back. The PRS crowd has switched primarily to 6mm’s, with some mild recoiling 6.5’s sprinkled in. The added recoil of the SAUM case didn’t really help for it to catch on. It seems that the majority of ppl still shooting it are using it as a LR hunting rifle or dedicated bench gun.
Maybe it’ll pan out for you, but there’s really not a great need for a SAUM gas gun imo. Ppl struggle enough with .308/260/6.5 creed’s in a large frame platform. A SAUM would likely be harder to shoot precisely. With a 22” 6.5 creedmoor making hits beyond 1100yds attainable from a large frame gas gun, without the need for specialized parts, lots of ammo choices, and numerous magazine choices, it leads to a market need that is likely met. |

Thing of it is, I'm still betwixt and between on whether to go with an AR-10, or a Bullpup https://www.ar15.com/forums/precision-rifles/AR-10-ers-bummed-by-Hornady-s-6-5-PRC-2-955-Max-C-O-L-Not-to-worry-The-6-5-GAP-4S-SAUM-option-/4-7781/?page=2#i115404 From another Forum ---

Quote HistoryOriginally Posted By SKY-PUP: Hoser, a suggestion: When the USA-made Prime Ammunition 6.5mm SAUM 4S product becomes available, order a couple boxes, or more. And, armed with a chronograph, compare the Prime Ammunition factory loads against your best handloads, at 100 yards, or more. Then, share your target and chronograph results with us. Once my 6.5 SAUM barrel is toast, I have zero intentions of rebarreling it to 6.5 SAUM. Why dont *you* get Jim to send me a few boxes of ammo and I will compare it my ammo at 100, 600, 1,000 and 1,200 yards. Hell, I will take it to our ELR match in Raton NM and shoot it out to 2,200. |

Hoser, I had hoped my suggestion would get you into the spirit of the Thread. Well, at least we agree that the 6.5mm SAUM 4S is a capable extended-range cartridge. When your ". . . 6.5 SAUM barrel is toast.", post a round count. Thanks. Quote HistoryOriginally Posted By SKY-PUP:

@sky-pup
I enjoy the testing, but I’ve been pretty slack lately. Between moving and a crazy work schedule, range time has been limited. Do you have the components to build an upper, minus the barrel? |

SuperJlarge,
I still have the American Spirit Arms .308 rifle that I used in the successful 2001 .300 Winchester Short Magnum conversion ---
However, I've since sold the .300 WSM Barrel and matching Bolt to a guy, who "had to have it" --- I kept my "Sidewinder" gas tube. If a proper Bullpup platform isn't available by end of year/first of the new year (when the USA-made Prime Ammunition 6.5mm SAUM 4S product is expected to go into production), I may decide to just go with the ASA platform (with the "Sidewinder" gas tube, or one of today's adjustable gas blocks), and order a 6.5mm SAUM 4S Barrel and Bolt, chambered for the new Prime Ammunition 6.5mm SAUM 4S dimensions. Bottom LIne: We're about to enter the 3rd decade of the 21st Century. I'd prefer to build on an auto-loading Bullpup rifle. |

I hope this degree of accuracy is indicative of what we can expect from the upcoming USA-made Prime Ammunition 6.5mm SAUM 4S ---
