What can your 6.5 creedmore do that my .260 can't?

[Hitzy]

It's just seem like the 6.5 CM is for crying lazy millennials. Cry cry flatter. cry cry less windage, cry cry less recoil. Sounds like a cartridge for pussies.

Millenials that don't reload... because that is just too much work.

And for the brass stretch/case design, here's separating on the 4th reload.

At the bottom shows how many times a 308 could be FL sized at max before fail, worst was 11, best was 24.

I do not even have time to begin to respond to this, but case growth and case head separation are two COMPLETELY different animals. Wow!

The first line of that linked post is ALL I needed to read.

Offer's more magazine space?
The 6.5CM truly is magical when it can magically lengthen the magazine box in any rifle you put it in! Amazing fact Chucky.
Better selection of rifles?

Again, just wow.

That is why I went .260


Because... Old school awesome....

Even if 6.5CM is more popular.... I like .260.

Funny how so many either don't get it or just plain ignore what the above pic represents.

 

[Buckmastr]

Tell us then. Based on your personal experience with both.

So true.

I've had short action 700s that I could not reach the lands with bullets w/o exceeding the mag box length. Some rectify this with a Wyatts extended mmag box for std 308 based cartridges. The shorter 6.5 allows for bullets to be seated out further which is AFAIC an advantage.

That’s a throat issue and has nothing to do with the cartridge choice.

Both seated to 2.800, 6.5CM holds less powder, what else are you trying to say?
6.5mm 140gr VLD are around 1.5" long, even in the shorter 6.5CM they still take up powder space.

Explain the difference then Chucky how case stretch and head separation are not related?

 

[Hitzy]

That’s a throat issue and has nothing to do with the cartridge choice.

Neither does mag length according to Chucky, as they 6.5CM will lengthen that too.

 

[jiffx2781]

Well after sitting back and watching this debate I've came to my conclusion:

Both cartridges have some minor technical pros and cons, NONE of which make ANY significant or practical difference in the field.

Anyone suggesting otherwise is just...

We are talking about trimming, not case head separation. Headspace is headspace.

Knock it off with the Chucky crap Hitzy, grow up.

I’ve come to a conclusion as well, and it has nothing to do with the 260 vs 6.5 debate.

It's a mag length issue. The shorter case works better in a 2.8" magazine.

Actually it doesn't work "better", it may work as good, or slightly worse due to the straight case and sharp shoulder. More taper with less shoulder angle feeds better, this was proven over 100 years ago.
2.8" is 2.8", one has more powder, which makes pew pew go faster.

It gets on his nerves....why would I stop? Lol

We are talking about trimming, not case head separation. Headspace is headspace.

So give me an example where the 6.5CM will provide less "trimming" due to it's design. When neck sizing? Should be the same as there is usually no need to trim neck sizing.
FL sizing? Well that creates head separation since you are creating space for the case to stretch on firing, brass flow which requires trimming.
