I have a CZ 550 that just had a trigger job, bedding checked etc. at gunsmith. He then proceeded to sight in with my norma oryx 285 gr. ammo. He said it shot sub moa at 100yds all holes touching. My dilemma is that i was going to Africa with 250 gr tsx and the 285 Oryx. I have not shot the TSX yet but am now thinking why bother. The game I will be hunting is Leopard, Eland, Wildebeest, Zebra, Impala and Hartebeest. Is there any reason not to use the Oryx 285 on everything ? Thanks for any advice.
