Funny thing about that. My CZ550 in 416Rigby has had the barrel cut to 21" a NECG front ramp with elevation adjustment and a flourescent bead. Barrel band front swivel installed. Brockman laminated stock fully glassed with a Kick-Eze pad (wouldn't use another one, too soft, deforms from sitting in safe) Scope is a Swarovski 1.5x4.5 in CZ rings. Last loads used were 410gr Woodleighs in Mast brass with 100grs of RL22 and Federal 215 primers. Bolt handle has been straightened and knob slightly reshaped with the hole filled in with a checkered wood plug from a piece I picked up in camp in Zimbabwe. My last elephant was killed with it and he didn't seem to notice the load or the barrel length. It is a very handy gun and makes getting in and out of the cab of the truck so much easier.
