CCI 400 and Rem 6 1/2 primers was developed for 22 hornet pressures, they are not ment to be used in the 6mm ARC!!!

CCI 400 primers are not as thick as others. They will crater/pierce at moderate pressure levels compared to CCI 450's or most other small rifle primers. I used IMR 4895 at 26.0 grains with cci 450's and Hornady 105 bthp bullets with good results, 2641 ave, SD 11.63 and 4 shots at .465.

When you are looking to use powders without accurate information for your application. Usually the website data is based on ideal burn speed for the application. PLEASE either use Quickload or Gordan's Reloading Tool to work up a starting load. Quickload can actually suggest the best powder from its database for your combination. START LOW and work your way up for safety sake. Had that first load been measured into a new SAAMI spec brass instead of your fire formed one, it would have been even hotter.. Thanks for the Video!

I commented on last video. Same rifle and was getting pierced primers in hornady factory 108 loads and with handloads. Since switching to lapua brass I haven’t had a pierced primer. I also switched to CCI BR primers about the same time. Can’t remember for sure if I used any CCI BR in hornady brass or not. Wish I could remember and maybe that would help narrow down the cause. Getting 3,000 -3,020 fps with 87 vmax and 27.8 - 28 gr benchmark. And 2,900 with 90 gamechanger and leverevolution 30.2 gr. I worked up almost 32 gr lever was getting pretty good pressure signs but no piercer primers or much cratering

That 25.3 is very impressive. I have zero experience with 6 ARC but I want to like it. In fact, your tests & content along with other guntubers out there have drawn my attention and appreciation to/for it. Surely the temperature stability of H4895 would be an asset for hunting seasons cooler temps. 2600 muzzle with this bullet should be good out to 300 yards for whitetail, especially with your skill and marksmanship. Can you expound a little on your comment on this powder being "too fast" for this load? That interests me. I am not an expert on reloading and certainly do not claim to be. I have been reloading shotgun, handgun since the mid 80s and got into rifle handloading a few years after. I have learned quite a bit more of late from you and your fellow guntubers. Thanks.

Some powders burn fast, for pistol like applications, some burn slow for Magnum rifle like applications. This powder is way too fast for 6ARC. If he's getting 2600 fps he's way way over pressure with most barrel lengths.

Wow! You should be getting 2500~ish with 25gr 4895 from a 22”, 52000 psi. Something is wrong. Edit: never mind, I thought your first set you started from 25.0. It looks like you were getting what you should have for those powder charges.

It is not the primers. H4895 is just too fast for the application. Not that H4895 is not a good powder. I have been beaten many times in 223 Rem matches by guys using H4895 but at a lower velocities than my best Varget loads.

This is absolutely a powder issue. Any research will show this is an incredibly bad load combo for this round and bullet weight. You'll be dangerously over pressure before your velocity becomes acceptable. 4350/Varget if you want to be in the extreme powder series otherwise live with leverevo/CFE-223/etc's temp issues.
