Please accept my sincere thanks and undying gratitide for your generous contribution to the robustness of my ignore list.

Just for the sake of discussion what is your thoughts on the 6mm ARC VS the 6 PPC? With Alpha offering quality brass for each chambering, for the Bench rest folks, is there much difference in the accuracy potential of either? In this example lets say we are talking the same barrel, barrel length, contour & twist rate on the same action. Would the luck of the draw on a quality barrel make more difference than the differences in case design?

Better yet for the average hunter using a light weight barrel would a shooter realize an advantage of one chambering over the other?

Two totally different platforms nothing to compare IMO, both do the job that it was designed for very well.

can shoot from an AR platform big freak-n deal.

Well, for people with AR's, it might be a big freak-n deal.

Don't know exactly why, though I became a fan of the CZ527 about 18 years ago as a walk about hunting rifle. While I like the 6.5 Grendel in that action for deer, I feel the 6mm ARC is perfect for the CZ527 action. JMHO

Fair enough. Yet I feel they defiantly have more similarities than other cartridges that I am familiar with.

If you shorten the freebore on a 6mm arc to run 68 grain bullets. And use it in a quality bolt gun, with same 13.5 twist barrel. You would have a 6ppc using 6arc head stamp brass. So it should shoot like a 6ppc to the degree of the gun and operator. In the 100 to 200 yard distance in which it was design.

I can only speak to the 6 arc that even in semi auto with a 20 inch Bartlein barrel. I've got to 0.375 Moa with 90. Grain and 105 grain Bergers.

I love the 6mm arc with 90gr bergers, I have a Savage with a 8 twist & Howa 1500 mini action with 7.5 twist. Both guns do well and for a young hunter or a lady to hunt with, and took them out to 600yds and they preform well, but if the wind is bad it shown up.

That's the problem with the 6MM with low-capacity cases, you need the heavy weight projectiles to buck the wind. If you want to push the light weight 6MM projectiles fast enough to reduce the time of flight, you need more powder increase the speed.

I use a 6MM Remington and push a 75 grain at 3,900 FPS and even then, 600 yards works for coyote sized game, but it gets tough for smaller game.

Ask yourself...who decided an ARC should be throated for long bullets and why.

Answer...Hornady and Marketing.
The cartridge shines brightest with light bullets but high bc is the cool kid right now

Well lets not forget the 6 Grinch with proper throat it's a much better cartridge than the PPC at the longer ranges. So as it says above Hornady comes out with the 6ARC with a longer throat and all of the sudden it's full of long range glamor. Frankly the longer and heavier bullets just choke the little cartridge's powder capacity. I tried the 6PPC with 8 twist and heavy bullets. The heavier bullets greatly reduced velocities and performance didn't appeal to me.

I did not read everyone's opinions on this topic, but I have asked this question to myself several times and have never really been given an official answer, so i went on a investigation over the last several years. My thoughts up to this point;

This is just what I have pieced together over the years of shooting my 6ppc, so literally take it like salt, sparingly.

Maximum amount of powder that can be put in the case. I have heard from several sources on youtube, that to maximise accuracy, the case must be as full as possible. Small and large rifle primers lean in opposite directions, generally, in terms of accuracy vs practicality.

100-300 yards vs 500-1000 yards, hence the bullet densities and twist rates. A minimal twist rate to suggest a bullet to rotate vs an aggressive twist rate to force a bullet to rotate. Take this with a grain of salt, both may be suggestive and the denser bullets may have drastic difference in the rotation. Just posting my observation and conclusions.

The 6ARC from my research, which is not a whole lot of research, comes from a different foundation all together. 6 ARC brainstormed from the standpoint of an AR type rifle, which means the shoulder angle will have to be shallow enough for fast reliable loading into the chamber from a magazine. The 6ppc in this case, not all, but most are bolt action single shot. I seen some sporter versions on gunbroker, but far less than single shot. Again just some thing i put two and two together on during my interaction with the cartridge.

Ammunition; Factory loaded ammunition and reloading ammunition. Sako stopped selling 6ppc ammunition here in the states many moons ago. If I find it on gunbroker, I buy it. Its great in my 6ppc. Yes its still available in its home country, but just not here in the States. 6mm Arc is readily available, although again take with a grain of salt as when you read this, it could come off like I am smoking out of my hiney, being there could be an ammunition shortage.

Lastly, the elephant in the room probably by this point. The 6PPC USA vs the 6 PPC with a custom neck diameter. My information, observations, and conclusions have all been from my Sako 6PPC USA rifle. While I do kind of flirt with the idea of ordering a custom built 6 PPC, it will always be that fantasy. I would never spend that kind of money on my hobby when it could be left to my wife to better spend on our family needs.

And lastly, for those who know of the family who have the Unashamed Podcast, Phil Robertson was diagnosed with Alzheimer's. Amen to the family and him!
