Help design the NZHS Forum Wildcat - Part 3 - Case

It fascinates me that you guys do this stuff. I am yet to understand why though.

It's fun Rushy. You should try it

Not yet

Looks like a 7mm08 with weight issues :ORLY:

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.

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 :)

Plenty of merit there :cool:

Using Lapua brass it would probably go surprising well, close behind the 7-08 if its smaller sister the 6mm-250 is anything to go by.

A slightly gruntier verson would the .284 Creedmore :)

It give's me the impression that it could be an incredibly accurate load if those number's work out as by the sounds it wont be screaming out of the barrel?.

If you consider 3000+ slow

Ever make your own home brew @Rushy ?

Proud to serve your own venison ?

It's not rocket science mate and you're obviously not short of the old grey matter

Never made home brew Tim. Drunk a fair bit of the dodgy stuff my old man made though.

C'mon @Rushy, stop being a grumpy old c-unit and join the fun.

She's pretty big job ay ....

Ha ha ha ha. Back to the original subject there are guys that tinker and change stuff to make it bigger, better, faster and then there are guys like me who just accept that the standard off the shelf stuff works fine enough for them.

Fair call

Here we have a visual comparison between the 7mmFEH and a Standard 7mm-08 on the right.

The Forum Elite Hunter is loaded with a 120grain BT and the 7mm-08 is loaded with a 140grain BT (to suit a long throated Sako)

As Kiwigreg alluded to 3050-3100fps might be achievable with Lapua brass, pushing the shoulder forward would be cool but necessitates fire forming.

Anyone have any thoughts on this, is it too small in capacity for general hunting????

Perhaps we could have a slight concept change on the Forum wildcat idea and have a Forum line of wildcats, this one could be the smallest and let's have two above it, to cover all our hunting requirements.
The mid can be the short 284 idea and the large, well, that's a whole 'nother thread :) :) :)

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.........

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

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.

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

Blues are naturally cool Gibo, you should know that:)

Hahahahahaha. R is before W or 7mm. Hahahahahaha

Crazy blue people...anyway, what about making the most of the new .270 LR AB and necking it to fit those or maybe the standard 130gr projo's. Would be a nice short action all rounder with moderate speeds??

Its a great looking wildcat, and would suit the budget consoius loader and under 250 yards it will be devestating on deer.
Might be time to get a 7mm.

Good point.

7FEH isn't that just a 7 IHMSA a 7mm based on a 250 savage (ie 22-250) case? if so i guess reamers are available off the shelf I looked at 7 IHMSA a while back and I remember reading that 300 savage brass is the preferred starting point as opposed to necking up 22-250 or 250 savage brass

I like the idea of a 7mm creedmore improved. shorter than a 7-08 so suits short actions like the rem model 7

I have this 7saum shortened 200 one working really well now after a few initial brass forming headaches 162 amax does 2930 out of 24 inch tube

Ha "Thunder chicken" classic. If you do a large magnum it could be ***HOT "HAMMER OF THOR!!!!" BOOM!!!! I just blew your mind!!. This is all i can contribute to this discussion. USERNAME OUT!!!

Might need to get a model 7 for this project :)

7FEH isn't that just a 7mm IHMSA a 7mm based on a 250 savage (ie 22-250) case? were you trying to do something unique? I guess at least dies, reamers, and load data are all ready available federal used to sell brass too but they stopped....

It certainly looks close, less taper perhaps.
