Help design the NZHS Forum Wildcat - Part 3 - Case

[Ground Control]

I'm a big 7mm fan , so I think its a great idea , how would 6.5mm go on that case size ?

I would like to say faster but increased bearing surface with the 120 grainers in 6.5 might even them up velocity wise, might.

Anyone played with the wssm case? (Super short magnum) that necked to 7mm might be quite nice, about 55grain of water capacity so should be slightly ahead of the 08. Would have a very short coal so would go in the shortest of actions. Bit more buggering around to get it going tho probably

A 6.5 would still have the original design characteristics outlined here.........

Had a wee think today about the suitability of a short 7mm as a forum wildcat.

I presumed it could have a few practical features.........

1. quietness and low recoil when suppressed. (Great for those 4 pound single shots !)

2. Economical to reload

3. Fits factory short actions

4. Std 22-250, 243, 7mm08 boltface

5. And 3000fps+ with 120 Ballistic Tips or TTSX projectiles for humane harvesting.


With that in mind I used a 7mm mandrel and opened up the neck of some Rem and Sako 22-250 brass.

STD 22-250 and 7mmFEH (forum elite hunter)
[

The 7mm/22-250 holds 40 grains of adi2208 to the neck shoulder junction, no doubt a faster burn rate powder would give us the velocity we need.

Shouldn't be too hard to get a reamer made, or use a std 22-250 reamer and a 7mm throater.

22-250 dies can have the neck altered/bigger bushing or blank dies reamed.

If the chambering is too slow or lacks excitement for some then a simple ream to 7mm08 returns the rifle to its former glory.

It's no LR bomber but bush edge and less than 250 yrds should see it in its element, - perhaps maybe

Now AI that 7mmFEH and you'd have a great little performer with next to no brass stretch and a mean looking case!

Except its a 6.5

Except its a 6.5

And pretty much a 6.5x47 Lapua or Creedmore right?

A guy on the long range forum has tried a 7mm wssm but not tested it, called it the .284 thunder chicken, must work extremely well with a silly name like that

Haha classic. Must be some merit to the design, would look cool anyway

Probably, and my idea is just a gutless 7mm rem mag

We are not trying to do anything revolutionary here, or cover unchartered ground, just trying to have a 'Forum Wildcat' or line of wildcats we can call our own, as we all know there is nothing new under the sun.

If it ends up being 'neat' or 'cool' and someone wants one for a bit of a play and to shoot shit then mission accomplished, shooting needs to be about having fun.

I was talking about the idea of necking down your 7mm FEH to 6.5 you touchy old bugger.

[Gibo]

Do you blues need to take 5, would hate to get admin to take care of themselves hahahahaha

[Wildman]

Blues are naturally cool Gibo, you should know that
