I feel fortunate to find this board. I was referred off of one of our competitive shooting highpower boards.
A tiny bit of background. I've shot competitively for about 12 years in the service rifle class. I have a High Master ranking. I have hunted since I was old enough to hold a gun. I used to think 200 yards was a long way. Now with all my background 300-400 seems like a chip shot.
Heres my dilema. I have a couple of 300 wtby rifles. I want a bit larger bullet and after having shot a 338 win mag a bit and seeing how it performs with the superb 225 X bullet I want to build in that caliber. The one gun I have that needs a barrel anyway is a Wtby Fibermark in 300 wtby.
I"d prefer a non belted round. A 340 wtby would be easy but has the same belt. I"d prefer about the best MV I can get so I have room to manuever. I was hoping for ballistics along the line of the 338/378 round.
I will be shooting barnes X bullets and I load my own ammo(going through some 4000-8000 rounds of reloads a year depending on how many matches I can make)
Finally I managed to borrow a 338 this year while I was bowhunting in Alaska. We could not get close enough to any decent bulls for my recurve. But the 338 was fun and allowed me to make 2 hits at 802 yards to collect my 'bou. So I feel that the 338 diameter works really well.
The rifle will be for large and dangerous US game. I am working on a 7mm for a 1000 yard prone gun so I'll have a smaller mag for smaller game.
Awaiting your advice. PS wildcats don't bother me either. I want something that works and will fit my action.
Thanks in advance, and Happy Thanksgiving!
Get as close as you can, but utilize your skills as needed.
I think you'd be happy using the 338 Lapua, or an improved version of it. You would be edging the 338/378 WBY pretty easily, especially with the lighter 225's. Lapua 338 brass is nice stuff, and it's built like a little brick **it house too. [img]images/icons/smile.gif[/img]
I'm building one this winter for the same reason. My brother has a Rem 700 in 338/378 WBY and its a nice round too. Much better brass with the 338 Lapua though.
A good friend of mine is going to be building a 338 Lapua IMP with my reamer at the same time.
I'm really impressed with the 30/338 Lapua IMP I had done this fall. [img]images/icons/cool.gif[/img]
Do a serch for "338 Yogi", it's an improved design of Dave Tooley's, and a few of the guys here use it too.
Brass costs more than the Ultra Mag does ($130 a hundred at Sinclair, or Brunos Shooter Supply) but it will last three times as long as the soft Remington hulls and is top quality stuff.
I have been shooting a 338 yogi for about 1 year now I shoot the 300g SMK bullets. I have taken deer out to 1225 yards with this combo. I am putting a new barrel on it this winter and building a long range hand gun in this cartridge. I am getting 3050 fps with a 34" barrel 10T with the 300g bullets. The brass is excellent and I have 17 firings on 48 of them. I have been thinking about using the 408 CT brass and necking it down to 338 for a long range hunting rig also.
If you think something is not possible move out of the way so the ones that are doing it can
If you aren't wanting to modify your bolt I would go with the 338/300 Rem UltraMag. Just neck up the standard 300 RUM case or down the 375 RUM and you have alittle more capacity than the standard 338 RUM which uses a slightly shorter case. I think the Weatherby has a generous mag box so length shouldn't be a problem, you'd just have to work on it alittle to get it to feed properly. This is just my opinion and others may and will vary, good luck with your project.
