Help design the NZHS Forum Wildcat - Part 3 - Case

[Rushy]

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

[Toby]

It's fun Rushy. You should try it

You haven't wildcatted the 7mm FEH yet ???

Not yet

Looks like a 7mm08 with weight issues

[Kiwi Greg]

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

Plenty of merit there

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?.

Nah don't think so Toby

If you consider 3000+ slow

[kiwi39]

Nah don't think so Toby

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.

[kiwi39]

Fair call

[7mmsaum]

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
