Re: .340 Weatherby or .338 RUM

Thanks for the info and opinions, I just put a deposit on a custom gun down at my local gunsmiths shop tonight. I settled on his own desing of 8.6 X 72 SDM. A Mcmillan A-5 stock and a complete over haul of my Rem 700 including teflon coated steel.

I saw a rifle, today, that he built for an ex military sniper on the same configurations and caliber and I must say it was impressive. The groups don't lie ( 4.5 " at 800 yards!!!) He shot a mule deer buck this past fall at a bit over 800!!!

This caliber will push 250gr. bullets at 3000 fps in a 24" pipe, so I made mine 25" and added a brake!!! It should be just over 26" overall.

Now I have to pick stock color and scope magnification. I'm thinking in the 4.5 x 14 x40 Leupold Mark 4. Should do me out to 1200 yards or so. Any suggestions??? As for color I'm thinking of sand with black webbing????

What is the parent case of the wildcat? Pretty hot performance to get 3000 fps with a 250 gr pill in a 24" pipe. Must be using the big Wby case or Rigby hulls.

Just curious on some specs!!

The parent case is an 8 mm Rem Mag. It is fire formed with no body taper a 33min 8 deg shoulder(.338!!!) an its performance is awsome. The one group I saw tonight was about a 1.75 - 2" group at 500 yards!!!!!!!

Re: .340 Weatherby or .338 RUM

I am a big time 340 nut case and have mo than a bit of experience with the road. (I'm on my 4th tube personally and have worked with many others)

To the point and end of resume

You were running a 250 at over 3 and that is a ton load for a 340. I've yet to of found one that would do over 3. I've found that 2900 is a very safe and comfy zone to end it at. Some will 2950 but I've not found one that I would push over 3 yet.

So, either you had an extremely fast and forgiving tube. Or you were really running the red line. And or perhaps you had a wonky reading of your clock and you didn't check it on other days and other clocks?

From what I can tell the RUM is gonna on ave best the 340 by 100 fps. If this is worth it then powder river let er rip.

Cost of 340 brass has never bothered me, and I usually run 10 or so loads out of a box. Have had em go as far as 12 and 13 on a few boxes.

I also used to make brass out of both 375 H&H and 8 RM. But, my time is too precious to me to bother with that any more.

On a side I love the big 33's and I really dote on them for long range work for chucks to elk.
