Help design the NZHS Forum Wildcat - Part 3 - Case

[Spanners]

Looks that way.
Will suss it out next week if no major changes

.284 shortened with the improved shoulder... 40degrees?

Sounds good Paddy, Run a .534 head dia and .550 body dia down to .535 where the 30 deg shoulder starts at 1.538 inches in length. Use the total brass length to 2.035 so you have a nice long neck.
Sounds like the ideal .284 to me.

So hows is making the dies for this?
Have you looked on the PTG website?
Ther is heaps of different cals on there
They will have already have done this i would think

Sounds interesting boys - May be a rechamber job on the horizon for my 7mm08

I will chamber a rifle in it.

Not only that, stock designs piss me off. Half the dimensions are hangovers from when opensights were the norm! The common "american style" design does not handle recoil well, does not line up with a scope well.

I suggest we rough out a stock design (which I recently discovered is easy) and send it to Senator to get made out of carbon fibre. Chose an action, barrel contour, etc etc and we have a NZHS Custom. We can argue about the optimum rifle construction for months. Am I getting ahead of myself? I see a batch of Howa actions and true flight ultramatches in the offing. Make an affordable super capable NZ rifle.

I like this idea as well. Could be an idea for a group buy rifle?

[geezejonesy]

anything built yet ? pics to show where u r up too ??
i ve no idea what u r building , a small anti tank gun?

Any chance we can source .284 brass sans primer pocket and give it a small rifle primer pocket like the fantastic 6.5x47Lapua. It would be a very very cool round. And very much unique.

I read a reply from a lapua rep a while ago regarding using small primers, they where having some issues with consistent ignition with heavier charges and even using the .308 palma brass necked down to other cals had some associated problems

I used them on my 708 project but gave up on them.
They gave less speed than regular large pocket 308 Lapua brass for the same charge & I couldn't get the speed back by increasing the charge as the CCI 450s would pierce before the 250s would.
I also tried brs, 400s & small federals as well...
Admittedly I was running them hard, but the large pocket would cope happily while the small primer simply couldn't match the speed.

I was running up to 2900fps with the 180 hybrids

Over 2900 the brass couldn't cope reliably

This was a special build with a long barrel & target action, so don't try this in your Tikka, etc .....

Or group buy components. You can get batches of Howa actions cheap, and they are nice actions. Finalize a design and specifications on here, source the components and have someone build them all.

The NZHS custom in NZHS Wildcat. It would be a collectors item!

Exactly what I was thinking. Howa's are a great idea. After all they're Sako's, just made in Japan.

Specs would need to be the same for all rifles to make it work I think.

[Cyclist]

Small primers are a BR conception to get rid of the last poofteenth of vertical (es) - i.e reducing the percentage of charge variation due to primer inconsistency by having a smaller amount of primer charge

I dont think a hunting rifle based on a Howa is going to need this level of pfaff? I dont want inconsistent ignition in a hunting rifle!

Would be effin cool to have a mainly NZ built rifle on sale though - be even minter if someone could convince Barnard to do a run of stainless actions (or Ti )

[Normie]

Barnards would be nice but they're pricey as well as being heavy. I think if the NZHS rifle was to be built it would need to be affordable for most and practical too.

My thoughts on specs are:
Howa stainless short action
TrueFlite #3 or #4 at 22" (flutes?)
Senator Carbon or McMillan Sako hunter Edge stock
standard Howa bottom metal and trigger but tuned to 2lbs or so.

One of the good smiths could be approached to see if they'd be keen to do it or not.

[Normie]

I think we should start a thread. It should definitely be a Senator. NZ made components wherever possible. Some variation on Sako 75 stock shape. Or just Sako 75 shape. Im sending mine to get moulded.

I agree. Affordable, and practical.

We should design or source a good rail. I think using one company (GW?) we could get a good price. Suppressed too I think. Pre-order, then bulk buy. Formalize the specifications and make the optimal kiwi rifle. Once the NZHS wildcat has its dies and reamer sorted, we can get look into a source for the rifle parts.

Yep. Sounds good?

Would other people be interested in this? For it to work/be profitable for the chosen smith maybe a ten gun minimum?

[Smiddy]

Just thought I'd say there's a member on here very capible of building this

Like the sound of that, do they do a left handed one?

[Kitto]

Waitaki engineering do a good rail too, got one for my tikka for $80 IIRC. Could be an option if we want to spread business around
