What Chamber for a very short action

[TonyR]

I have a 7X64 Brenneke F-Open barrel and it is very accurate. The cartridge is very similar to a 280 Remington except slightly smaller in all of the body diameters. David Bailey won the F-Open Nationals this year shooting a 280 Rem. But the cases are 30-06 length and the OP was asking about short cases and the 7X64 is not a short case.

Greetings from Hawkes Bay Foster.

The early suggestion of a 6.5x47 is very good IMHO.
I've had the lot and the 47 performs way out of proportion to the case size. Accuracy is unbelieveable and 130s are def in its comfort zone.

The only negative is the brass cost but they last really well. I've put 4-5 rounds through mine using the Redding Comp dies and no sign of needing a body bump yet

Have fun

Tentman, if that Kurz action is basically un-molested, you can sell it & buy several 700 actions.

Ha - I have to admit that I am a mauser snob of the worst sort, I waited for years to get my hands on a kurz (then I got two bubba'd examples in quick succession) so you'll have to prise them from my cold dead hands . . . the example I have to rebuild from now has no bolt (not too hard to remedy), and a barrel that is toast.

Tentman -

Howdy, again !

Forgot to mention, I call the 7X35Rem wildcat " 7MUP ".

Comparing to 7 X 64 Brenneke:
That case is notably larger in capacity than the notional 7MUP wildcat I mentioned.
The Brenneke case is 64mm long, about the same as a .280Rem. I believe 7X64 exceeds the practical case length limits you stated.

The 7MUP wildcat case, is around 55mm long ( 1.920" ). That's comparable to a .260Rem case, in length ( .243Win, et al ).
That should give some idea of the relative performance potential of a 7mm wildcat, based-off .35Remington as the parent brass.

While I have formed 7MUP sample brass, I have not as yet had a barrel chambered for it.


With regards,

Lots of great info here but I do have a question. Initial statement said "the 308 family of cartridges are too long" yet much of the discussion has been about the 7-08, the .260Rem, etc. which are nothing more than 308 Win. cases necked down. So how can these fit if the parent case will not?

If a really shorter 30 cal is desired, I'd go with the 30BR, or even a 6 or 7 BR if a small bore is desired.

case is to short 1.555... won't launch a 130 ~ 150 gr bullet efficiently enough for hunting round

6.5 WSSM

I second the 6.5wssm. 140gr @ +3Kfps
BUT, you really do need a WSSM action in Savage(which is awesome). They are larger in diameter to get enough barrel steel around the chamber to allow running +60Kpsi before reaching extraction issues.
They're also CRPF, standing blade ejection, and IMO, all actions should be by now.
Sorry not a .473 suggestion, but this is the most viable way to actually do what I suspect that you want.

I am building two sporters on Model 7 actions: 6.5 x 47 Lapua and 250 Savage - both cartridges are ideal for an extra-short action - either should be good hunters for you.

 

[Larryh128]

Tentman,
I just measured one of my 6.5x47 Lapua rounds loaded with a Berger 130 VLD & it will fit into your Kurz magazine length. A exceptial round that is very capable of extreme accuracy and terminal performance. I'm shooting only a 23" hunting barrel & still getting 2800+ without any issues. RL-15 & Varget appear to be solid choices and I know that you won't have any issues getting varget.

For a hunting rifle my choice would be the .358 Winchester.

308 Win. and it's derivatives are too long for his action.

 

[Larryh128]

Magazine length of a Kurz action (true short mauser) is 2.72 inches.

 

[25AI260]

30 T/C Cartridge like a .308, bullet weight ranges 125~180 gr bullets but has the same col: 2.640 for all...

sounds like a good hunter..
