New out of the box my 455
was not a shooter averaging 1-1.5" @ 50 yards with some 2"+ groups. Needless to say for all the accuracy hype around these rifles I went home mighty disappointed. I did a PHD's worth of research on RFC about the CZ and it re-kindled some hope for my gun. Maybe it just needs some more shooting to "break in" the barrel but by and large many have had good results from bedding this rifle. Thought I'd share my experience. I make no claim to being a master gun-smith I'm just an avid do-it-yourselfer. My work can't hold a candle to some of the masterpieces the RFC guys put out but is a fair representation of what your average Joe can do for themselves.

I started by pillaring using 2 1/8" x 2" brass nipples from home depot. Got my length by using the depth gauge on my calipers from the wood inlet of the bottom metal to the action in the stock and cut/filed the pillars to +0.01" of that. I had made up a couple M6x1 studs when I bedded my .270 so I threaded those into the action holes and wrapped enough tape around them to snug fit and center them in the pillars. Pillars were put over the studs and secured to the action with a nut. Drilling out the stock for the pillars was a bear since I do not have a drill press or any such nice machining equipment. I used a piloted #12 countersink bit with pilot drilled into the center of a 1/4" wooden dowel to help guide my hand drill. This was not perfect and still bounced around the stock, popped out of the inlet, crooked etc... I used a few larger standard drill bits to ream out the stock to my satisfaction that I had enough clearance around the pillar to fit it straight. There is something to be said about the right tool for the job.


I used 5 min epoxy but much of it pushed out the bottom when I inserted the pillars and set up too quick to settle back down when I flipped the rifle resulting in a large void at the rear. The front fared better and they were both solidly located so I reasoned the voids could easily be filled next when bedding the action.
