Wildcat appreciation thread

Yes it’s the only option once you go the “wildcat” path.

do you use magnum primers?

No, Fed LR primers, Norma brass with RL25 pushing 140gn AMAX at 2980 fps.

Greetings All,
As it was another wet day here in HB an expedition to the shed yielded some 6.5x60 Wire formed cases. They measure 57.5mm long so almost 1mm longer than the 6.5x57 and have a shoulder that is around 40 degrees. The dia at the shoulder measures 11.4mm and the length to shoulder 47mm. These are a little less and more respectively than the .257 Roberts Improved. I don't know any more about the rifle than what I could see and the gentleman that built it has left the range. It was built on a 98 Mauser action and fitted with an reticle moving variable scope. From memory the barrel had a 10 inch twist so would not handle the heavier projectiles.
Regards Grandpamac.

Hey @BRADS I see you listed the 22/204 aka 22 Terminator. How did you find it vs a standard .223? I’ve contemplated it for a bit more horsepower in that bore size. 1-8” twist of course….

Awesome, better than a 223 in every way except the brass forming.

Mines a simple one no reamer involved at least yet.

I got frustrated with a model 7 7mm saum not being able to seat close to lands and fit mag.

Barrel came off and chamber was shortened 200 thou from the rear and polished at the rear to increase diameter slightly (thanks Mitch Maxberry)

Got a form die made up with 4 sequential inserts (Spencer tool and grind USA) )to make a 200 thou short saum. After 4 trips through the form die cases are trimmed first with a lee trimmer in drill to get rough length then wilson and then annealed and neck turned. Norma brass is so soft only 1-2 annealings required to finished case. Early attempts with rem brass were more tricky. I shoot 162 ELDM's under 51.5 grains 2209 CCI LR primer at about 2800 out of 24 inch barrel. capacity/performance is about the same as a modern 7x57AI

Resizing is done with a redding body die with 200 thou trimmed off the bottom and a modified Lee collet die (300 wsm body, 7mm mandrel shortened 200 thou).

Been running it over 10 years. 50 brass last about 5 firings before most are lost in the tussock. About a 10% loss rate per reload batch. Forming fills in a few winter evenings once every year or so. Finding new norma Saum brass is challenging (thanks Sidney for selling me my current batch at a great price much appreciated)

Here's a .224 I messed around with a few years ago: https://www.nzhuntingandshooting.co....wildcat-48771/

Just started a new high performance. 25cal wildcat that I'll take a few pics of when I get a chance

Wow that .224 is awesome

I'm also chasing buying a 303-22 complete rifle that comes with brass, dies and the chamber reamer that it was cut with

That's an interesting wildcat

I also have 303-25 dies and could make a chamber reamer based on the brass they form
That's a pretty useful wildcat

How are you getting on with the 303/22 purchase? I dumbly sold all my 303 reamers a few years back ( got a few in a bulk purchase ). Was always keen on a single shot in 303/25 or 22. Always wondered about taking out an encore barrel in 223 into one.

Work in progress on buying the 303-22

The 303 case family is generally bigger than what's currently considered safe in a contender but it would bolt in on an encore

If the twist was right it would be a nice round.
I do know where a 303-22 chamber reamer is but not sure which of the various lengths it is

Will get on to it ASAP

[Wingman]

Here's the. 250 Sika I'm working on.
6.5-284 Lapua brass necked to .25cal and blown forward to a 40deg Ackley shoulder.
I have reamer sorted, dies nearly made and a few cases mocked up. Going to run a s/s 1-10 to 1-8 progressive twist vulcan barrel.

Along side a 6.5 creedmoor both loaded to AIS mag length
