The CM is a great round. We’ve taken it well past a mile and it’s awesome. For normal ranges......almost too easy

Zeus, what are the range limitations of the pistol version?

My 11 YO went 7/8 at 450 on some turkey steel. That was his first time to try it last summer. I haven’t shot the pistol past 600 myself. The problem is glass on the handgun. I DO NOT like rifle scopes on handguns so I’m stuck with the normal crap we always are for handguns I guess. I wish that Vortex or Leupold would build an awesome handgun scope for us to use with first focal plane and turrets like a rifle. Basically, take the small 3-18 and make it EER. Razor line with 34mm tube would be great. Or S&B. Anyone?? Would be amazing and change the handgun game for steel and long range work. I think they may be surprised at how many they could sell honestly.
But to answer your question, with good glass, you would only be limited by velocity and environmentals. The handgun shoots like a rifle.

Ross Seyfreid wrote an article on how premium bullets have changed the effectiveness of our cartridges, and allowed us to drop down in weight and still obtain great terminal performance. Even so far as to tout his mentors (EK), despised 270 as a great elk rifle, when using premium bullets.
I’ll post a link to article here in a bit, gotta get ready for work.

Were I going elk hunting, which I probably never will. And for moose hunting. I'll take my 338 Win or 375 Ruger or 375 Whelen A.I. or possibly my 458. If I was caribou hunting or predator hunting and a nice bull moose walked up. The Creed would put hundreds of pounds of moose meat in the freezer. Since my farthest shot on caribou to date was with the 130 gr TSX, a flat based bullet that leaves the muzzle @ 2775 fps, 373+ yards . Dumped it on the ground. And other bou I've killed with it. I have confidence in how the carbine, cartridge, bullet performs. If it wasn't for fox, lynx and coyote, I prolly never would have got a 6 5 . But, I'm Real glad I did.

I personally have never cared for the 270, but I absolutely love the small 6.5’s from 6.5x55 on down. On medium game I’d never feel undergunned with one, and if something larger presented itself I’d just place the bullet precisely and continue on. Even though I do prefer bigger rounds and more bullet weight for game larger than medium size, 338, 358, 366, 458, and 510 are always available in the safe.

Just to follow up and update my findings on performance with a short barreled 260rem. The 18” barreled AR10 platform has exceeded my expectations with regard to velocity obtained from the short barrel and velocity loss when compared to a longer 22” barrel. I will not list the powder charges but all other ammo specs are shared. 18” barreled JP 260rem. (All cases used are LC 308 converted to 260rem) 120gr Hornady GMX, Hodgdon Superformance, LC case, 2935fps avg. 129gr. Hornady SP, Hodgdon Superformance, LC case, 2806fps avg. 140gr. Sierra GK, Hodgdon Superformance, LC case, 2704fps avg. The LC cases used a bit less powder than what was listed as max. for each load from the Hornady data book, and showed no abnormal high pressure signs. I dropped each charge 3grs from the listed max. and then worked back up, when I hit my expected velocity without any abnormal pressure signs, I increased until I got slightly cratered primer strikes and then dropped back down .5 grains and called it done. Loads were developed in 60-70 degree central Texas humid winter weather. The Superformance delivered 40-50fps velocity loss between the 22” barreled gun and the 18” gun, Hodgdon H414 was also used, but when Superformance exceeded it with velocity and showed less loss I stopped using it on load development. I don’t know if the barrel is fast, or if Superformance just works really well in shorter barrels, but I’m ecstatic with that kind of performance from an 18” barrel.

Have you tried H4350, Rl17 or Rl16 in your 260 ? Trapr, that is Very impressive for velocity !

CTF, when I was developing loads for my LR Comp. gun n 260, I had tried several of those powders, and others. I settled on H414, as it gave good velocity, consistent through a wide range of temps, some of the matches could be in single digit temps and others in 100+. Accuracy was also very good and consistent. Several years ago I had purchased an 8# jug of Superformance to try with a Ruger #1 in 30-06, when the rifle wouldn’t hold consistent POI, even with the tricks that are supposed to work, I sold it. That jug of Superformance, went unused until recently while trying to find a good load for my new 30r Blaser, ironically H414 wound up being better suited for it. But the Hornady load manual had loads for Superformance in the 260 so I tried it,.....lo and behold, it found a new home and use, I went and picked up another 8# pounds of it last week. Trapr

Good deal! I tried Superformance in my Creedmoor but didn't get the results I was hoping for so went back to H4350 and Rl17. But, like you I still have some of it. I'm going to see if it will work in my 338 next. I don't know if Win 760 and H414 are still the same powder. I used lots of 760 in 375 H&H loads a long time ago . And had a good meat load with 414 and a 270 gr Hornady SP. In my last H&H.

Rwt, i shoot with suppression all the time, during culling operations and destructive animal abatement, basically a lot of shots and talking with other shooters or game managers. It’s actually a pain in the A$$, lugging around the extra weight, luckily most of it is short stalks or walks and a lot of vehicle travel so it’s not too bad, but even a short can 5” long turns a nice handy rifle into a cumbersome, heavy tool. Some of the LR comps I shoot guys have taken to using cans on their rifles, and we hike 3-5 miles shooting along the way, the rifles already weigh 12-15 pounds and they want to add a pound or more to the rifle??? Hunting with a can seems more of a novelty to me, you’re typically alone and you’re shooting supersonic ammo,....you’re not stealthy and quiet once the gun goes off, animals are leaving. For me, I see little to no benefit to “hunting” with a suppressor.
