Finally settled on a wilcat, .30-375 Ruger


Registered Users do not see the above ad.


I have a guy that's going to run it through quickload for some estimates. I would like to see it get close to RUM velocities, without having to lenghten the mag box, or alter the bolt face. The .375 Ruger case would allow this. If it hasn't been done yet, I will call it the .300 Cana, after the small (tiny even) town I live in.

Yes, I could probably just buy a new rifle in .300 RUM much easier, but what is the fun in that ?


Edit:
In my paper guestimations, based on averages from the 375 Ruger and 375 RUM, Im getting the 30-375 Ruger pushing a 200gr right around 3000fps. About 4% below the RUM, and barely above the Wby Mag. Ofcourse my guesstimations have nothing to do with efficiency.

So this is a 375 ruger case necked down to 30 caliber. Yes it could be fun, however what are you getting velocity wise in your 300 wm with 200 grain bullets?

Actually, Tang......you can get 3000 + a little from a 200 grainer in a .300 Webby.

But anyone can have a .300 Wby. A .300 Cana .....you just don't see every day.

Good luck on your adventure.

Go far it you will enjoy it in the end. I have a custom made 350 Griffin & Howe which is a 375 H&H necked down to 35 cal. It cost more to shoot because of brass and dies had to be custom made but in the end its different and I like it.

As you can see by the edit, I kind of shot down my own dreams there. I dont want to build it, if it doesnt atleast better the alternative. Oh well, thought I had a good idea going. Guess the .300 Roy aint that bad of an option either.

Still pondering the .300 Cana, with more paper bench racing.

With RL25, the .300 Win Mag case holds .896gr of powder for every grain of water of its max capacity.

.300 Win Mag = 86.4gr of water
.375 Ruger = 94.6gr of water

Thats a gain of 8.2 gr of water. So lets say it will be a gain of 7gr after the neck down takes place (the .300 RUM has 1 gr less than the .375 RUM). Ok I averaged all the loads for a 200gr bullet listed in my Lyman manual, and I come up with it gains 39.6 fps for every gr of powder.

So .300 win mag has a max load of 77.5gr of RL25, so with the new added capacity, I get 84.76gr of RL25. Thats roughly 7 more grains of powder. So 7 x 39.6 is 277fps. So add that to the 2901 of the RL 25, and I come up with 3178 fps with a 200gr bullet. So in a sense, I recreated the .300 Wby, minus the belt and in a 30-06 length action.


Disclaimer: I by no stretch of the imagination, expect this to be accurate, and no one should even think of trying the loads I have listed in this post. This was imaginary fun.

I saw an article on this on another website...I think 24 hr campfire or something like that...they'd already built one I believe. But I'm using my memory here...and that can be dangerous!

Build you a 350 Griffin & Howe and then you can sling 250 grn bullets almost 3000 fps, 220 grn bullets around 3100 fps, and I'm not sure what it would sling 200 grn bullets at but I bet they would be digging out.

I had one custom made with a 26" barrel and it is a sweet shooter. Just another thought plus its fun looking at all the different cartridges.

See. I told you trusting the memory was dangerous! Thanks for the correction.

In the M700 you can use the RUM or 375H&H length rounds with no mods. With this wildcat, you could use a std. Ruger action obviously since they do in a 375 Ruger now & other std. length actions as well, if that's important to some.

It would also appear to offer great potential in the way of accuracy much as the WSM does, but in this case MORE power than the 300WM & Wea. If I did not have a 300WM Sendero I would be interested too & I see the appeal.

Good luck

Tang.

a 30x375 Ruger will be very close to the 30 Newton. The Newton was ahead of it's time being an "improved" case design ie, minimum body taper and sharper shoulder. The 375 ruger is very close to the original Newton in case dimensions although the Ruger is "improved" a bit more. I think the shoulder angle is a bit sharper, maybe a shorter neck.

I think of the Ruger as a 375 Newton Imp.

Hope this helps you in your endeavor

Todd

Just checked Fred Zeglins site z-hat. He lists the 30x375 Ruger as an available reamer for rifles.
Thanks
Todd
