I have had a #1 in 416 Rigby sinceRugerfirst came out with them in the early 90's.
The cost of factory ammo is a bit high but handloads can be had pretty cheap.My particular rifle is "scary" accurate and is a solid performer. I suppose the company guru's figure they can find a few more hunters that are going to want anothertraditional African carttridge with the 450/400 Nitro.
I think I am going to pass due to already having the Rigby which ballistics surpass the Nitro.
