A question for those in the know who may be able to guide me along on this one. I have a CZ 550 Medium Lux chambered in 9.3x62, with a 23.6 inch (600mm) barrel, and the barrel is marked with a 1:14 twist rate. I took it to Namibia last year with factory Norma Oryx 286gr ammo, and was very happy with it. It performed well on all the plains game, and is pretty accurate too. This rifle seems to like all of the 286gr stuff I feed it, with the exception of some factory Hornady 286gr SP Custom International for some reason (does not group well).
Anyway, I have located a set of RCBS dies, a friend willing to roll me up some and an itch to tinker. I know that the 9.3 built its reputation on the heavy for caliber bullets, but I was looking to flatten out the trajectory somewhat. I was wondering if perhaps a lighter bullet may do this for me, but without losing any of the 9.3's potency. Here are the bullet choices available to me here in Canada:
Cutting Edge 210gr ESP Raptor
Cutting Edge 255gr Safari Raptor
Lapua 220gr Naturalis (Lead Free)
Barnes 250gr TSX Triple Shock FB
Barnes 250gr TTSX BT
Hornady 250gr GMX
Norma 232gr Oryx SP or Vulcan SP
Nosler 250gr Sptz Accubond
Swift 250gr A-Frame
I don't necessarily want to hotrod this rifle, but maybe some suggestions on bullet choice, powder choice, and the speeds I should be trying to achieve to get the bullet to perform as it was intended to?
On the other hand, you could just tell me to stop messing with a good thing and keep shooting the Norma factory stuff too.
I would be open to any opinions or suggestions of those who know.
Thanks
