6.5 CM

Re: 6.5 CM

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: fredjake1</div><div class="ubbcode-body">Wondering if the 6.5CM has and advantages over the 260, case design- balistics etc. </div></div>

Pros
•Almost identical case capacity to .260 Remington
•Long-range factory loads to be available from Hornady
•Quality yet affordable brass to be available
•Load recipe printed on factory ammo boxes
•Better case design than .260
Cons
•Still new. Component availability to be proven.
•Is different than .260 but doesn't offer substantially more performance
Match Performance
I haven't yet had an opportunity to run the 6.5 Creedmoor in practical/field matches. Based on its accuracy and ballistic performance, I expect it to provide exactly the same results as .260 Remington. Dennis DeMille shot the 6.5 Creedmoor during the 2007 NRA High-Power Long-Range season and had great success. It is reported that as soon as he switched to the 6.5, his rapid fire groups and scores went through the roof, and he set a new personal best at the 600 yard line with 200/15X.

Summary
Hornady has the right mind-set to make its new cartridge a success in the competitive and practical market, unlike Remington who basically let the .260 languish in a few hunting rifles.



This is just a portion of an article that I found, you can read the entire article if you search for shotgun news March 31st 2008. I shoot a 6.5 creedmoor as do a few of the guys that I shoot with here in Vegas, the creedmoor seems to be a very capable rifle. Hornady has been a little slow at times as far as availability of their match grade projectiles ie 140 grain AMAX. Two of the guys I shoot with have switched over to the Lapua Scenars because of the availability issues and they have seen good results as far as balistics with the scenars. If you look up the entire article that I copied you on they had specific ballistic tables for both the 6.5 and the .260. Hope this helps.
 
Re: 6.5 CM

Pros: Better brass, "maybe" better barrel life.

Cons: have to run it hotter to get equal (if you can) velocity out of shorter barrels, brass can be a pain to find and more expensive.

I've had both, now I only have a 260. No fuss brass and can be made easily from other cartridges. So I guess to answer your question case design is better if you have enough tube to get you the velocity. Ballistics are determined on how fast you want to run it but the primer pockets will loosen up if it's too hot of a load over time.
 
Re: 6.5 CM

they are both awesome rounds. I believe dennis won camp perry with the cm one other advantage that i can think of for the cm over the 260 and i am a huge 260 fan is that for almost the same case cap the cm is quite a bit shorter allowing you to seat bullets further out if you like riding the lands and still fit and feed well from a mag.
