Home Forums Hunting & Shooting Ask The Gunwriters 6.5 Query for Mule Deer

John,

Do you think the longer neck, sharper shoulder, and slightly lower max powder charges of the 6.5 Creedmore might result in a significantly longer barrel life over a .260, or is it just Loony hair-splitting?

Thanks.

They all would help extend barrel life, but exactly how much would also depend on the powder used and the barrel. Plus, of course, how hot it gets shot!

I was operating under the assumption that those factors you mentioned would be pretty much equal. Given the near-dearth of .260 rifles available, I suppose it's really mostly a question for re-barrelers and those doing a build. As I noted in an earlier thread, I've got all medium capacity 6.5s pretty much surrounded by other stuff, so none of them are likely in my immediate future, barring a burglary or fire.

Thanks again.

The 6.5 Creedmoor has better barrel life than the 6.5-284

Ya think?🤔

25% less powder just might have something to do with that.

That, and there are those who try to make it into a 264 Win Mag.

I have a new barrel on my 6.5x284 Serengeti. Haven't shot it much but did get this out of it:



Not bad for the third group out of the rifle.

I think that just might be good enough...

Nice to see somebody actually getting their money's worth for a change.

With all the discussion about 6.5 CM vs .260 Rem or 6.5x47 Lapua, I haven't heard much about the 6.5x284 lately, other than a tendency to burn throats too early.

Are they not known for accuracy, or is it just a short accuracy life, with their shoulder, neck & throat geometry ?

Upon reading these types of posts I wonder how much money is spent on the ammo to wear out a barrel. Quality ammo today costs just under a dollar a round to make. Lapua brass a buck a piece, quality bullets at half a buck a piece. And, we're not talking about competition guns. Just food for thought.

I've never seen an actual 6.5X284 rifle in the flesh. I guess I've been to happy with my 260. I have bought a bunch of the 6.5X284 brass though. It is great brass for making a cartridge that I use in a BLR as well as a Winchester 100. It is the 7X6.5X284.
