Guns, Bows, Shooting Sports, and Hunting 6.5 Creedmore vs 308 Win

[CBlack]

Was reading through the M1-A thread and saw a few mentions (praises) for the 6. 5.



What is the big difference between the two?



I've looked at ballistics but wanted opinions from the fellow gun nuts.

CBlack, What would you plan on using it for? Competition, general shooting/plinking, hunting?

Both are good cartridges. I do like the . 308. I am building one, right now. Its been a long term project.

I also like the 6. 5 Creedmoor for several reasons, all academic. A well balanced case capacity and design, supersonic capability at 1000 yards with a standard length barrel, longer barrel life than many of the other new 6. 5's, light recoil, short action capable.

IMHO, the only disadvantage is the proprietary Hornady brass. It is soft and has QA/QC issues. If Winchester and Lapua offered these cases, I would spring for the tooling and a barrel to build one!

Hopefully, HHhuntitall will weigh in on this one! GregH

It's a pretty easy thing to form 6. 5 CM brass from 22-250 or 250 savage brass.

6. 5 has a flatter trajectory due to a better ballistics coefficient. Long range target shooters prefer it.



That said, both of my long range rifles are in . 308 and I do fine on about 1/3 the cost per round.

. 22-250 and . 250 Savage brass is notoriously undersized at the base. The cases look pregnant after they are fired. 6. 5 Creedmoor brass is dimensionally closer to the chamber diameter(which is proprietary and similar to the . 308 head size), which means less working of the brass at the head. I dont recall the overall length of the Creedmoor case. When I get over to the shop, I'll get a measurement. When necking up and fireforming a case, you will loose length. More so if the base has to expand . 010" because of an undersized case. The point of this is fine accuracy and precision. Not get-by strategies.

Yes you can make a 6. 5X22/250 improved or a 6. 5X250 Improved. BUT that is a custom reamer to fit the brass! Measure a REM or Win . 22/250 case at the base or a . 250 Savage. Then measure a 6. 5 Creedmoor at the same location! Yes Lapua makes great . 22/250 cases with a preferable head size. Just not sure of the finished length after necking up and fireforming. GregH

Get by strategy? It's as hard as you want to make it pal. I'm continually amazed at how some people insist on struggling through stuff. Might be time to get out and actually try some of this stuff instead of just talking about it.

Sorry you got yer back up! My comments werent meant to be disparraging. As far as experience, if you need to know, I've been reloading and shooting for close 50 years. I started gunsmithing back in the early 1970's. While I have not shot or built or formed every case configuration out there, I've done quite a few. Enough to know what works and what is a get by! Do what works best for you! Be careful with assumptions about folks on the other end of an internet connection. If you are satisfied with the accuracy potential with cases formed from . 22/250/s or . 250s in a match grade barrel chambered for the 6. 5 Creedmoor, be my guest. I would not! Thats what I call a get-by! Respectfully, GregH

 

[CBlack]

I'm wanting to use it for long range shooting as well as just plinking/fun, etc.

Thanks for the feedback from everyone.

I'd say if you got a lot of $$$ go with the 6. 5.



The advantages of the 6. 5 are:

Better bullets for long range.

slightly less recoil.



Disadvantages:

Loaded ammo and reloading components are more expensive.

Roughly 1/2 the barrel life.



I'm sure this isnt all, just thinking off the top of my head.



Dont get me wrong, I'd LOVE a 6. 5 creedmoor, but for my purposes my old 308 would do fine.



If youre into the 1000yd matches, the 6. 5 is a plus. At 600 yds and closer I dont think it's worth the extra $$$.

My . 02 I have shot a . 243 in long range competitions for awhile now without any problems reaching 1000yd mark. Its all personal preference and putting in the time shooting down range. Plus 1000yds you are not trying to kill something but be accurate and consistent. What works for me or the other guy is not gonna work for you. If you are willing to put the time in then whatever caliber you chose will not really matter. Its just money... ... my . 02
