Interesting tidbits of info on the 6.5 Creedmoor

[J.Baker]

This is food for thought for everyone who's bought a new rifle in 6.5 CM and had troubles with the bolt not closing fully with some ammo.

Wow! Just another reason for me not to grow a man bun and jump on the 6.5 Creedmore bandwagon. 260 all the way!

He's only discussing half the problems.

He's only discussing half the problems.

Do you want me to bring the video equipment out this weekend so you can do a video covering the other half? LOL

[Texas10]

Interesting video. Curious as to how old it is and if this problem still exists.

I have a new, still in the box 12FV in 6.5 CM that I have yet to chamber a round in, and now guess I'm going to have to check it out.

I have shot American Gunner 6.5 CM (Hornaday brass) and hand loaded Peterson LRP and SRP for my other 6.5 CM (Savage action, EABCO accuracy barrel) without problems. Did I Luck out or has the problem be resolved?

Good find, easy to gauge his frustration with being blamed for ammo not chambering. Agree with the throat, not shot any factory but I’m sure not surprised about the case headspace QC issues. Impossible to find good help these days.

Dave Manson ground my reamer with a .145 throat. I believe SAAMI is .178 or the like. I hate the thought of jumping a mile to lands while using a short action receiver. The manufacturers are doing it in order to reduce chamber pressure for all these hotrod loads so folks can drive the 140’s faster than they should. I guess a lot of the bullets don’t really care, as many people continue to demonstrate, but I don’t share the same experience.

I've had a 6.5x55 since before the creedmoor ever came out, and will continue to have a 6.5x55 after the creedmoor fad calms down. I have not seen any reason to get rid of it in favor of the creedmoor, and stuff like this makes me happy I chose the right cartridge.

Video was published this past February, so it's fairly current information. It's been an ongoing issue since the the round was standardized by Hornady and continues to have these issues. As he noted, you can order new Hornady brass and it's a crap shoot as to whether you'll get brass that's been annealed or not. The inconsistency in the distance from the case head to the neck/shoulder junction is something I ran into with factory Federal and AE ammo when I reviewed the Model 10 Stealth the other year. I didn't have any that I couldn't get the bolt to close on, but some required noticeably more effort to get into battery.

The gunsmith gets all the problems at his door step. My 12fv Creedmoor has been trouble free in every way. I would build another one without hesitation.

The Creedmoor has been out for a decade now, so most any competent gunsmith or barrel maker should have discovered and addressed any issue they had with their chamber reamer if they got one of the bad ones with the shorter throat.

The ammunition and brass issues are the big issue here as after all this time the inconsistency problem still persists. The brass inconsistency isn't even that huge of an issue because if you're doing things right you are FL sizing your new brass before loading it the first time. Unless your dies are long it's going to push the shoulders on those longer out-of-spec cases back to where they need to be, and then they will all be fire-formed to your chamber after the first firing and you can adjust your FL or neck sizing die to get the appropriate 0.002 to 0.003" shoulder bump.

The real problem lies with the brass inconsistency on factory loaded ammo. If you don't typically shoot factory ammunition you're good to go, but if you don't reload it's an issue you need to be aware of and watch for.

^^^^^^^^^^^ This

^^^ This, x 2
Sizing new brass solves any handloading issues, assuming a FL die is used at least for the first loading.
Throating is always going to vary anyway depending on weight, and type of ogive. For the most precision, throats are cut independently based on an actual handloaded round provided to the smith.

It's the factory ammo which is apparently a problem (not aware of it)- no doubt sloppy/worn machining working past it's capacity keeping up with demand for the cartridge. This isn't a problem with the cartridge- it's the ammo and brass manufacturers as he says. Gotta say though, I've not heard these outcries he's referring to.

[want2ride]

I still can't believe some people are calling it a fad. Do you understand how ridiculous you sound?

[sharpshooter]

Should we start a list of "fads"?

[wbm]

Yes.

I listened to the video closely and have questions about his statements. First of all. brass is annealed numerous times during manufacture in order to do the drawing process. Next the part about not annealing brass because of no case discoloration is most likely just wrong. Some manufacturers go an extra step and clean the brass when it is finished. It just looks better to the consumer. When I started getting case separations with my 6.5 CMs, I found the problem to be excessive headspace using a Hornady comparator with a .40 bushing. Since this is the datum line diameter, I feel that it is close. I shoot a mod 12 LRP and a Ruger PR. Both the chambers show the same shoulder to base. The difference is that the LRP is .020" longer to the lands. That is a little difference in throat length, but all my bullets seat well. I have used a few different makes of brass and have found that the shoulder of his favorite was running about .007" shorter than my chambers. New brass can be sized smaller, but it has to be fireformed to stretch it. I watch for the tell tale rings on the bottom of new brass and check it with a paper clip the first and subsequent firings.. Hornady is not the short shoulder manufacturer. As far as fads go, I think that I will have my 6.5 CMs for a long time. I have never shot a round that is more forgiving of loads and bullets. I don't think I have ever had a round that would shoot half inch and smaller groups at 100 yds with factory ammo before my 6.5 CMs. The reason that I like it so much is that it's just all around good. I shoot a lot of .223 Rem, but it is unforgiving of small differences in bullets and loads. That's a round that is high maintenance to me. Let him check .223 Rem chambers and brass if he wants to make a video on factory defects. I get my fun running ladders and trying different components with the .223s. This has been sort of windy, but I think he needs to get out of the shop and shoot more and enjoy the 6.5 CM.

This has been sort of windy Windy is fine sometimes. Good write up.

Creedmoor? Never trust a cartridge named after a location in Queens, New York.

.260 Rem for me as well.

I'm sure the 6.5 Creedmoor is fine. You kids enjoy your new stuff. Just don't shoot yer eye out.

This has been my experience as well. I have 4 Creedmoors. 1 factory and 3 customs. Awesome cartridge. Blaming the cartridge because of inept ammunition and firearms manufacturers is ludicrous. My 3 customs have never fired factory ammo. And Savage rifles have been the ones with the most chamber problems.
