.300WBY Mark Vs

i find that they are about the same i havent realy did alot of shooting with the 200s but i could do the same groups as the 180s
talk to ya all later

I had a Japanese Mk. V and it shot the 200gr Partitions extremely well...3/4" with a max charge of IMR 7828. The 180's did no better and even if they would have, I wouldn't bother. The extra weight of the 200 is nice when going up against big critters. Plus the damege to deer, as long as you don't shoot them in the shoulder is minimal.
 
My own mark V shot 180's the most accurately but would not consistantly shoot MOA reguardless of the load.It was the biggest disappointment accuracy wise of any of my rifles.My personal favorite .308" bullet is now the 180gr tsx.If this bullet won't get the job done when fired out of my 300ultramags,the job requires a bullet considerably larger than .308".
 
I have an older German made Weatherby and I've had better luck with 180s but I think thats just by fluke. I would rather it shoot 200s or even 220s but it prefers 180s.
 
My dad tried 150gr factory loads from his Voere Titan II .300Wby. It shot ok, about 1" - 1.25" @ 100 yards. I've loaded 150gr Nosler BT's in my .300 Win Mag and got 1" groups. My 180gr Accubond load gets consistant .5" or better. The 220gr Partition shoot 1" all day. FWIW I don't shoot 150's any more. Don't really see the point.
 
I've loaded everything from 150 to 220 gr bullets in my 300 Mk V (early German as well). The groups were much better with the heavier bullets, and slightly better with the 200's in mine (compared to the 180's). Oddly enough, the best groups I got were with 190 gr Hornadys. I never had any luck with the lighter bullets at all, at least not at speed. If I held them to roughly 308/30-06 velocities, they worked ok, not great but ok. Anything above that and they were all over the board. I have some lighter Triple shocks to try out this year tho', so we'll see how that goes. - dan

I think you should try those out when I come to Edmonton :D
 
Try a 200gr Accubond with IMR 7828; I used 83.0gr with the 200 Partition. That is the maximum charge in the book, but my rifle didn't show any signs of pressure. You should start lower and work up. The other note is that Weatherby rifles have lots of freebore, so you should seat your bullet as long as necessary. My OAL was well past industry max.

I'll have to remember that suggestion, as far as OAL goes...It'll be seated as far out as the mag box allows...

I'll have to measure, but I don't assume the specs have changed and should therefore be 1:10". It's a Japanese made one.

That SHOULD be good for 180 - 200 grain bullets, you just have to try several different loads and see. Depends on what your rifle likes from now on!:confused: :confused:

my scientific mind likes formulae...not guesswork...hence me probing for info :D

Scientific minds are best satisfied through experiments and testing! Now go load up a bunch of ammo and head to the range.:D

Well, I'm not a Chemistry kinda guy...more a Physics guy...That's why I'm taking Engineering at the U of S. Too bad all of my Reloading equipment is 3 hours away and not set up...

I like classical physics, but thats where it ends. Once you throw calculus into the fray I start to gag.:(
