I am looking at 416 caliber rifles. I slightly would prefer the 416 Rigby, because of the wide availability and variety of factory ammo--from fairly mild loads like this (http://www.midwayusa.com/viewProduct/?productNumber=522212) to near-Weatherby loads, like this (http://www.midwayusa.com/viewProduct/?productNumber=728499). I also would consider the 416 Weatherby. I also would consider the 416 Rem.
For those of you who have experience with any of the 416s and rifles listed below, could you offer any advice? I was considering (with approximate price):
$3,500: CZ 550 with the AHR Upgrade #3 listed here: http://www.hunting-rifles.com/CZ/CZowners.htm
$3,500: Weatherby custom Mark V Dangerous Game Rifle:
$2,400: Ruger M77 Mark II in 416 Rigby: http://www.ruger.com/products/m77MarkIIMagnum/models.html
$???: Blaser in 416 Rem.
What is the best gun/cartridge combination of those in terms of value, durabilty, reliability, strength, etc ...?
Thanks in advance for any advice!
