Yeah a 270 130 grain bullet going 300-400 fps more then a standard 130 grain 270 is no difference, yet we have campfire members who go to improved cartridges all the time that gain maybe 100-150 fps.. See the Mashburn thread for an example.
It also seems that people somehow think that Mark V's are 9-10 lb rifles, maybe a visit to weatherby.com will educate them so they can correctly compare apples with apples.
Ammo availability, LMAO, I can't remember the last time my local gun stores had 270 win,7 mag and 6.5 creed moor in stock.
I have had/have 4 Mark V 270 WBY both Japanese and US made. Not one has not shot factory ammo better then any 270 Win I have owned, despite a tad more recoil and muzzle blast.
