This is a real long shot because I'm nearly certain no on on here is familiar with this wildcat.

I was recently talking with JES "the guy that has done a few barrel rebooring for me" about a project I had him do for me a 7600police in 308 with a 16.5" barrel that I had him rebore to 358win. I was telling him that I am becoming a bit of 35 nut as I have all of them now and he says you don't have a short mag yet. So he told me about the 350wsm wildcat and how well it worked in 18"-20" barrels well as you guys know that intrigued me! They are 300 or 325wsm brass necked up to .358.

I have a tikka t3 in 300wsm that I don't think I have carried in the woods in the 10 years I've owned it and I don't really know why. But a 225gn .358 dia. bullet and right around 2900fps is pretty eye opening.

I have a 350 rem that I recently bought and brass is nearly impossible to find and its in a right handed gun so I'll most likely never use it and don't have the money for a full custom 350 rem in left handed.

But for 250$ I could have an awesome wildcat in a very neat cartridge.

I guess my question is for anyone who has ever had a wildcat did u find it worth it? I know a deer will never know the difference between a 358 win or a 35 whelen or this 350wsm. But it will be a fun project and very cheap already owning the rifle. I also have nearly 500 300wsm brass that is becoming hard to find that I could form so that should last me my whole life.

What do you guys think of my new crazy idea?

I have a .325 WSM that is built for Elk hunting.  I do not believe it gets more than 2900 fps at the muzzle of a 24" barrel when I use a 200 grain bullet in it, so I think your velocity estimates are very hopeful for a .350 WSM using a 225 grain bullet from a shorter barrel.

"The 180 grain BST bullet has a catalog muzzle velocity (MV) of 3060 fps and muzzle energy (ME) of 3743 ft. lbs. The 200 grain Accu-Bond bullet has a catalog MV of 2950 fps and ME of 3866 ft. lbs. The 220 grain Power Point bullet has a claimed MV of 2840 fps and ME of 3941 ft. lbs. These Winchester velocity figures are averages taken from a 24" test barrel."

It might make a very nice deer rifle in a unique chambering, but I doubt it would be worth the constant hand loading effort and initial expense, if you compare ballistics to a .35 Whelen or other rounds like the .358 Win.  In the end you may find the velocity you are getting is less than both of these.  Maybe you'd be better off just going to a .325 WSM?

Thanks for the info!

2900fps was a typo, 2800 seems to be the common number and that would be 150fps faster than my whelen and 300 more than my 358 carbines. The having to reload isn't really an issue as I reload for most of my rifles now. A 325wsm doesn't interest me because I have all the .358 and .308 bullets and I like to keep like components.

Think long & hard about building a freaky big bore. :) The resale will be horrid..........

You'll probably tire of it after some time and then if you want to flip it to fund another urge, it'll be painful.

I had a wildcat built a number of years ago and I don't regret it at all but I do know if I wanted to flip it, I'd get squat.  My .223 ai is a great shooting gun and I know I could rebarrel it to any number of other chamberings as you could too, maybe.  WSM sized actions are limited to what you can do with them.

If you build, I wanna see it. :)

I'm the guy that hack sawed a barrel on a 1300$ Benelli R1 before I even had a scope on it. You bring up a valid point for sure but I don't build or buy things for the next guy that might own it. I have to put more thought into it but I'm pretty sure it's going to happen. My only hold up now is the recoil in a sub 6.5lb carbine pushing a 225gn bullet at nearly 2800fps is kinda scary!

Well, if you're gonna do it.........a friend built a 35WSM and it is a shooting machine!!




Got any info on it for me? Twist rate barrel length what action? I'm surprised there isn't a more consistent name for this thing I have found about 5 different names for the same thing. It makes finding info very difficult.

I'm sure my friend would be happy to talk about it.  I just texted him, I'll see what I can find out.

I do know it's Winchester Model 70 action; he bought a great condition 300WSM stainless gun and tore it down.  Kreiger barrel and 'smithed by Sid Goodling in Pennsylvania.

Oh Heck!, Go ahead.

It's just plain FUN having something new and different! 

If we were worried about the paper or on game ballistics, no new cartridges would ever take off.  And like you said, you  reload and already have the gun  and brass.  It's just a rebore on the tikka and some custom dies.

Good luck and keep us informed!!

Jaeger

and oh yeah, HAVE FUN!!

It's most likely going to be a winter project but I think it's getting done. A gun shop buddy of mine tho is he knows where a custom set of dies are that can be bought so I think it's down to just the gun. I'm excited it will be a gun that can kill anything on North America and be light and short like I like them.
