WSM WILDCAT

[Con]

Shane,
Are you using the 300WSM reamer followed by a .416 neck and throating reamer to get a 416WSM??? If so ... we really need to have a chat about some other wildcats ... I assume your already set up to do stuff like a 338-08 (338Federal) etc... ?
Cheers...
Con
PS: If MAB are rough ... where do you place Sprinter C/M barrels ?

Tez,
No i havent had to do any 9.3 WSM's, most likely because there are quiet a few 9.3/35 cal's already available that will do the same job.

As one example, the 350 rem, what you shoot will never know the difference between it and the wsm.

Some of the yanky die makers would make the 9.3 wsm as a custom die but they would be very expensive.
cheers,
Shane

As much as I love my 416Taylor if I were to do a wildcat on the WSM that was to be a dedicated Sambar gun it would be a 9.3. So thats how I voted.

You can use a lighter barrel than the larger bores and try for an overall weight of about 7.75 lbs . It will be handy to carry and still comfortable to shoot.

Approximate ballistics for 9.3WSM
250gns at 2700fps for 4050 ft/lb
286gns at 2600fps for 4290 ft/lb
320gns at 2400fps for 4100 ft/lb

The 9.3x62 established its world wide reputation over 100 yrs with286 gns at 2350fps with 3500ft/lbs. This makes the 9.3WSM just more of a good thing
Cheers

Tez,
I tend to agree with Shane in that I can see no reason to spend money to build a 9.3WSM when so many existing cartridges do essentially the same job. There are no readily available factory .416s at the moment other than the Wby (MarkV) and Rigby (CZ550 mostly) and the market I feel has always been prime for a short/mild 416 along the Taylor lines ... or possibly Ruger if they commercialise it on the 375Ruger case.
I think you should stick to the original plans and build a 416WSM ... its nice having a readily available spitzer shaped projectile in the Woodleigh 335gr PP, plus the heavy 400gr if you ever want to chase something larger.
Cheers...

Id got the 416 too.
for me the 416 calibre is the 6.5x55 of the big game rounds- why question it- it just works.

It seems that these WSM Wildcats are getting quite a following in the US.

Lastest Rifleshooter mag has a review for the 25 Proghorn(.257).
100gn partition=3729fps=.750 .

110gn Accubond=3613fps=.490

100gn Barnes TSX=3706fps=.625

110gn Hornady SST=3527fps=.550

All loads near max.

Winchester Classic Stainless(Was=300WSM),HS precision stock,26" fluted stainless barrel(1:10).

Siske are also playing around with the WSM as well as the ugly WSSM cases.

Lay of the petite WSSM ... I've actually thought it would be kind of cute with a 35cal projectile stuck on-top.
It'll also be interesing to see whether Rick Jamison starts exercising his patent rights on the WSMs or whether he'll go broke trying to defend them all .
Cheers...

"Well it looks like a good idea.

I modelled you wildcat as follows

Neck length - 0.344"
Shoulder angle - 35 deg
Shoulder diameter - 0.538"
Case length - 2.1"
Base to shoulder length - 1.756"
Case capacity - 79.8 gr of water

The 9.3X64 Brenneke has a case capacity 82 gr.

Ballistic data
Each cartridge is loaded to 62,000 psi max avg
Load data is with the same powder in each case.
106% compression for the wildcat
105% compression for the Brenneke
Bullet - 286 gr

Wildcat (300 - 9.3 WSM)
65.3 gr of powder
Muzzle velocity - 2590 fps

Brenneke
67 gr of powder
Muzzle velocity - 2614 fps

Pretty close."

Hey Con,
Yes i can cut quiet a few chambers buy using a base reamer and then opening up the neck and throat to suit.

My reamer list can be largely expanded further by doing so.

Basicly yes i can cut quiet a lot of wildcats.
cheers,
Shane

After much thought I've decided to give the WSM Wildcat a miss .
Reason,well I could not be farked at this point in time on a Wildcat.

Now I have a much better idea(Cal),& one I have wanted for a long time= 9.3x62 .

So my 300WSM will be back on the market .So if you are keen on her buy it,or offer me something I can use for my 9.3 project(30-06 action).

If I can't find the right rifle I will be just buying a 9.3 newby .

I'm a bit late on this one, but Clem Stevenson (the bloke behind the Aussie Stalkers) is building me a 416SM on a Weatherby shott mag action, with a docked Ruger #1 Rigby barrel fitted. Barrel length about 21 1/2", and a fairly heavy profile. Stock will be a straght laminated job, and the scope a Leupy 1.5-5X20 VXIII with the Illuminated reticle. Clem is pretty busy on these and other things, and I'm trying very hard to be patient; apparently he's almost been inundated since the write-ups in a couple of magazines. When it turns up I'll get together with blackpete (he wants the first five shots!) and we'll do a writeup on it.
anyone interested in that?

[Blackpete]

As abopted godfather of this new bouncing baby boomer I'll be happy to write up all the info I can in a compelling review. Geoff (Woob) has kindly offered his latest addition to me for a trip up to Wiz's place for comprehensive testing on Buff, just have to try and work out how to pay for the trip (and bribe Wiz). I would love to see this round in a leaver action or a Rem 7600 (with pistol grip).
Pete.

[woob614271]

I've had a cople of phone conversations with Clem Stevenson, and h has the barrel in the 416SM and has test fired it successfully.
He'll egister it in Newsouth and send it up to a local gunshop while the paperwork goes through. As for blackpete taking it up to Wiz' place to test, I have a nephew in 5/7 RAR who wants to test it too (in Iraq maybe?) so who gets it will be interesting...
Question:
By the way, does a 416SM count as a varmint rifle?

Shane just a quick question for you

The only reason I ask this is because I've be caught out when I had my 416 Taylor done

If you use a 300 WSM reemer and then throat it with a larger calibre you end up with a longer neck..........

I asked for a 416 Taylor, the gunsmith cut the chamber with a 338 WM and throated it with a 416.

I sized down som 458 brass in the 416 Taylor Dies and it wouldn't chamber in the rifle, ....that's crazty I thought.....then I necked up some 338 brass and it did chamber, that's when I realised I had a 338-416, the neck is longer because the top of the shoulder is set further back and you loose a fraction of the case capacity.

The 338-416 is definately NOT a 416 Taylor. The 416 Taylor and the 338 WM have the same length neck, so the gunsmith neededs to blow the bottem of the shoulder up (similar to ackley process) making longer case walls, not bringing the top of the shoulder down which is what happens when he throated with a larger cal.

I handed my Taylor dies back to the gunshop, told him the problem and he was going to get a set of 338-416 dies made for me, (reworked a set of RCBS 338 WM dies), well that was back in December and no dies yet.......this whole thing has been going on sine about August/September last year

I thinking it would be cheaper to get my rifle reemed out the extra few thou, bringing the bottem of the shoulder forward, to make it a legit 416 Taylor and get my old dies back

Infact it's not my fault I should be just insisting I want it redone. In any case Shane would it cost much push a proper 416 Taylor reemer back into the chamber.

S&F

Hi S&F,
i read your post with intrest as i too am considering a 416 Taylor build. During my reasearch i found that the Tayolr can be made from the 338WM or the 458WM brass. The differance i noticed is that the 458 brass has straighter walls and apears to have a slightly larger diameter than the 338 brass, this may explain you trouble getting it to chamber.

A friend of mine has built a Taylor based on the 338WM brass and from what i can gather it works fine, Wiz is his forum name and he may be able to shed some light on the subject for you.

Pete.
