I have a Accumark Mark V .270 Weatherby Mag and love it. The only problem with them is the ammo costs minimum $40 a box. I started reloading it and am getting good results (the factory ammo is very good also just expensive). I have killed mule deer and elk almost every year with it and for the caliber it is very flat shooting and knocks them down good.
I am working up some loads with 150 gr Nosler ballistic tips. My best group was with 72 grains of Relodr 25(bottom left, shot that is off was me) averaging about 3200 fps. Let's just say the gun is a better shooter than I am.
This is a very good rifle for open areas. I use it in central Idaho a lot.
