Currently, in the stable, I have a 455 Varmint, 452 Lux, savage mkiiF and a Savage mkiiBV heavy barrel in a wood stock. The 455 and the Savage mkiiF are mine and the other two my wifes.
The mkii was my first gun bought at a gun show with a Japanese Tasco mounted and I am still very happy with it. I did have to remove some material from the barrel channel on the stock as the synthetic stock was contacting the barrel if flexed. 15 minutes with a sandpaper wrapped dowel fixed the problem. Only other tweak I have done was to torque the action screws. It is an accurate gun and the action is smooth as butter. It was well broken in when I purchased it though.Of note, I helped a friend set up his brand new synthetic stocked mkiiFV a few weeks ago and the barrel channel had a lot more clearance and no need to relieve the channel.
The 452 lux was my wifes first firearm. I gotta say out of the box it was perfect and the groups settled in nicely after 150-200 rnds. This rifle is also set up (as it should be) as an off-hand shooter. Nothing, other than cleaning, has been done to this rifle and it shoots wonderfully. the hog back profile of the stock makes fitting a scope low enough without the bolt handle contacting the occular bell a bit of a challenge.
I was so impressed with the wifes 452 that I immediately set my sights on a CZ of my own. I wanted a heavy barrelled Varmint for sure and liked the idea of being able to swap barrels and calibres with the 455. Out of the box I was a bit worried as the accuracy was not great. The rifle was beautiful but the groups were all over. I checked the crown with a Q-tip and felt a few snags so I pollished them out using a cone shaped Dremmel bit by hand. The bit I used is green and has a grit that I would liken to 1200. I also retorqued the barrel retaining screws and stock bolts. This seems to have fixed the issues I had and groups have tightened up. It is a comfortable rifle to shoot but the heavy barrel makes off hand shots tiring. I have this rifle set up with a bi-pod for bench type shooting as that was my intention for it.
Last, but not least, the Savage mkiiBV. The rifle that got my wife interested in getting her PAL was my mkiiF so she wanted her own Savage. While cruising the EE I came across a heavy barrelled, wood stocked model being sold with a bi-pod and scope already mounted for a good price so a deal was made. This one is older and has a bit of a different action than my mkii. It had a bit of a problem feeding rounds from the mag but a little tweaking of the magwell and all was well. This one is crazy accurate. I did a full cleaning after receiving it and then proceded to sight it in to our normal .22 shooting distance of 40 yrds. When I was sighting it in I thought I was missing the paper all together. After walking down to the target I realised they were all going into the dot I had made with a black magic marker that was roughly a 1/2". Of course this was a used rifle and well broken in but if I was going to bet a few beers on group sizes I would compete with this one.
So I guess the long and short is, the CZ's are beautifully crafted heirloom quality rifles but don't discount the cheaper Savage. In a head to head between my 455 and the wifes MkiiBV the cometition would be close but my CZ would look better doing it.
