6.5 Creedmoor vs. Other 6.5mm Chamberings

[Mr Wick]

I'm seeing SMK Bullets that say Sierra Bullets 6.5mm (.264). Lapua Brass that says 6.5x47, 6.5x55, and 6.5 PRC.

I have just a regular 6.5 CM Rifle. What are all these variances?

Those are not Creedmore cartridges, those are different.

 

[SEGARE]

Those are all 6.5mm/.264 cartridges as is the 6.5CM. They don't have anything in common other than the diameter of the bullet. There are many other 6.5/.264variations beside the ones mentioned here.

The Creedmore family has expanded to include 6CM, .25CM, 22CM.

 

[Mr Wick]

Is there a difference between 6.5 CM and 6.5X47 CM? And what bullets am I going with? I just ordered basic 6.5 CM Lapua Brass. I want to go 140 grain. Why am I seeing mm next to some things?

Do you have a good current reloading manual? All these are different chamberings. If you don't have one, buy a reloading book like Hornaday's reloading manual. All your questions will be answered.

What is it you are trying to do?

Those as you call them variances are actually different cartridges.
6.5x47 Lapua
6.5x55 Swede
6.5 PRC Precision Rifle Cartridge
These are not what you have.
You have a 6.5 Creedmoor

 

[Mr Wick]

I have read it. I was geared more towards the .308 that didn't have all the different cartridges. I will read it again though.

Ok. Everything is clear now. I totally get it. I need a .264 Projectile.

There are many similar cartridges that are not interchangeable. Just to give a visual of some that vastly different. Left is the 6.5 CM, right is the 6.5 PRC.

They have lots of factory ammo in 6.5 Creedmore, try some of them before you start reloading and while you get familiar with things. Factory ammo is safest way to start this addiction.

Thank you. I understand it now. The cartridge differences and the use of mm threw me off. I need a .264 projectile for my 6.5 CM Lapua.

There’s also small primer and large primer brass for the 6.5 Creedmoor.
Someone in your other looking for brass thread was trying to show you some Lapua small primer brass for sale in the classifieds.

Yes. I shoot large rifle primer Lapua. Thank you. I have been shooting the Hornaday 140 grain ELD Match Ammo while I wait for all my new reloading supplies.

Welcome to the sport, it is an awesome hobby and really good advisors on this forum. Any doubts at all just ask, too risky to assume.

 

[Mr Wick]

I listened to everyone and bought the Redding Type S Full Length Bushing Die with the the Bullet Seater. .336 Titanium Nitrate Bushing. IMR 4350 Powder, Lapua Brass. Just deciding on projectiles. Got a new Magnetospeed V3 Barrel Mounted Ballistics Chronograph and Head Space comparator too.

I think that bushing must of been for your 30 caliber.
Creedmoor would be like .289 or .288

Damn it. I bought the wrong one. Thank you for pointing that out. That was for the .308.

 

[MDT6BRA]

Yes I agree with McGraw. Study up on presssure signs too, they are your warning signs.

I will be doing a lot of reading as I have time before my Powder and Brass get here. For the Redding Type S FL Die you recommend. 288 or .289?
