Input needed for CZ 452 LH improvement



Log in to see fewer ads
I have a CZ452 left hand American the didn't win the wood lottery, has not shot impressive groups, has a real nice trigger, and is always shot off a bench. I am thinking of putting a (21-24 inch) Shilen bull barrel (1 inch?) and having a custom stock purchased for it. I would pillar bed the stock and leave the action and trigger alone. Two challenges I can see are: finding a good smith to do the barrel work, and finding a good left hand BR stock for the action.

Any input that will help meet these challenges as well as other pertinent information about soundness of this project would be appreciated.

Have you played around with different torque values on the actions screws?

I start at 20 lbs./in for front and rear action screws and work up from there.

Some suggest starting at a lower value (15 lbs/in.) and work up slowly.

I purchased five 452 American rifles (4 for my 4 nephews) and adjusted each to get very nice groups.

Skip the barrel fo4 now. Go on eBay type in klinsky stock , I saw a left handed 452 stock for $150 last week. Or pillar bed your stock so you can get a rock solid stock fit.

After reading your post again I notices "bench only".

So I would agree with Toomany22s and try a new stock before a new barrel.

This one starts bids at $50 + shipping

Breaking in

I thought by breaking in my CZ 452 would give me better results. It d1d but now at over 2000K rounds I can easily hit MOA at 50 yards with a Yo Dave kit installed. Now finding the best ammo / lots will be easier. No bedding or pillars yet, just free floated and then installed a bike tire rubber piece 3 inches from the front of the stock in the barrel channel.

Try a little bedding under the chamber and at the tang. Pillars are not necessary. After the spot bedding at the front and rear, play around with the action screw torque. Also, some rifles can be finicky with how they ride the rest. Experiment by moving the rifle fore and aft in the rest and see if you get any improvement.
