Where do I find case capacities for several 6.5 cartridges?
I'd like to compare the 6.5 Schuler, 6.5 RWS, 6.5 Brenneke and 6.5/06.
After comparing capacity I'll research brass availability and so on.
Thinkng about a new build and I think it's a 6.5 I want but I also am thinking of an 8mm like an 8x68 or something approaching a Rem 8mm Mag.
Thanks

Quickload has most of them.

I see you did not mention the 264 Winchester Mag.
I had one, a pre 64 Winchester Mod 70, the one with the stainless 26" barrel.
It was my second Centerefire rifle. Many times I wish I still had it.

It would shoot groups at 100 yards you could cover with an American quarter.

I love my 264 WinMag, but I think a matched set of 6.5x68 and 8x68 would be perfect. I was thinking about a similarly spaced combo by rebarrelling another M70 Extreme Weather to 358 Norma Magnum. As already noted, you didn't mention the 264 WinMag, but I will say that I did find some case capacity for Norma brass and individually tested loads at http://www.realguns.com/loads/264winmag.htm. I'll be testing the 160 Woodleigh PP/Retumbo combo today.

While I wait for my to cool.
Here are some numbers. From my wildcatting with the 6.5 I think something around 71-73 is ideal. Past that you really start burning powder for smaller and smaller gain.
26 Nosler 96.4
260 Howell 71
6.5 Gibbs 73
265 RCBS 68.8
264 W Mag 80.7
6.5 Rem Mag 69.3
6.5-06 AI 68.9
6.5-06 65.7
6.5-257 57.6
6.5-284 65.5
6.5 STW 92.2
6.5 RWS 68
6.5 Brenneke 67.

I always thought the 6.5STW was a waste now the 26 Nosler is even bigger.

Paul I could not agree with you more. I appreciate your opinion about the ceiling of diminishing returns, I think along those lines as well. Where is the 6.5 PDK I don't see it listed?
I have a Mauser action that needs a project and
have always thought I would like a 6.5/06 but was thinking about something metric (because it's on a Mauser) in the same class. The action is standard bolt face standard length action.
The 6.5 RWS and 6.5 Brenneke have some appeal to me but I don't see as yet any real advantage over the 6.5/06 or maybe the 6.5/.284 AI.
I appreciate everyones input.

6.5 PDK is 75grs.

So maybe the ideal is more like 71-75.

I would have to think that the 6.5x06 would be a hard choice to beat, with the easy avialibility of 30/06 cases.

Want metric, call it the 6.5x63

Depends on what you really want in terms of ease/economy/availability of finding components.

ANY wildcat/factory based cases such as the 308, 30-06, 284, WSM or belted mag have already been done and the brass/dies/reamers etc are readily available and the factory offerings are all excellent cartridges so I wouldn't bother trying to reinvent the wheel.

You start going down the oddball road, like the RWS and Schuler and Brenneke to a certain extent, you just get yourself all twisted up in knots. Those can be accomplished but the effort is substantial.

My picks would be the Swede or 6.5-08 at the lower end, 6.5 RM, 6.5-284/'06, then the 264 last...you can download the 264 to the middle sizes ease enough or go heavy for heavy bullets...the 26 Nosler would be a distant last for me and only when the disease of magnumitise hits me.

Again, because ALL the reloading/shooting components are readily available and/or easily made pretty much and easily obtained online or from local sources.

If you want something totally gnarly and bad go for the 26 Nosler and don't look back.

I think your question has already been addressed at some length, I have a vague recollection of it, so you might do a Google search and pick up additional info that way.

The 6.5 Brenneke is essentially a 6.5-06 with a slightly more tapered case and less sharp shoulder.

I built a 6.5-06 to replace a 256 Newton that I wanted to retire from shooting. But by the time I got the stock built for it I found out it had a slight mare in the chamber from the reaming tool and the gunsmith had passed away.

Simplest solution was to clean out the chamber by going to the 6.5-06 AI version so I did that.

Brass is easy to make from 25-06 brass that is available everywhere. It shoots nice and is easy to reload. Run the brass over an expander plug and fire in the AI chamber. RCBS had the dies on hand but were in the $160 range. Essentially I use 6.5 Brenneke load data that I bump against "regular" 6.5-06 load data.

I'd go with either a 6.6-284 or 6.5-06. IMO the beauty of the 6.5mm is that you can get excellent down range ballistics without burning a huge powder charge, thanks to all the high ballistic coefficient bullets that are available.

Nothing wrong with a 6.5/06 and if you call it a 6.5x63 then its as metric as anything !!

I have used a 6.5-06 for 23 years now and I highly recommend it.

The 6.5 SAUM seems to be getting some attention lately as well.

The 6,5x63 Messner Magnum. Nota bad one either.

Sure looks like the 6.5-06. Wish I could read it.

It´s a 9,3Brenneke necked Down to 6,5mm.

The 6.5-06 is a gem. Feeds like a dream, nice long neck and cheap brass that needs no fire-forming. It's pretty easy on powder and seems the perfect volume for a lot of suitable powders to get top velocities without compressed loads or half empty cases. I love the 260 as well, but the 6.5-06 is way more versatile.

go with the 8x68, heavy bullets at high velocity.

If it is a 6,5mm you search for, consider the 6,5x68S Shuler. I'm gathering parts and pieces for one on a Mauser GEW action. NECG offers brass and loaded ammunition.

I have three .256 Newtons, in addition to my 6.5X54, 6.5X.257 Roberts, 6.5X57, 6.5/08 (.260 Remington) and .264 Winchester Magnum.

The Newton cartridge is a treat to shoot, especially in my original Newton rifles, but at 64 grains of water is on the verge of being over case capacity. Cases can easily be formed from .270 Winchester, .280 Remington and .30-'06 brass.
