CZ 452 Silhouette Accuracy Tuning

I recently set up my 452 Silhouette for silhouette shooting,got the trigger downward to 2 lbs and installed a Weaver KT15 in BKL high rings,I have simply fired at at 25 yds so far for accuracy with Wolf MT,accuracy seems ok with some groups at 1/four" at this altitude,some were larger,my question,is there any accuracy improvements I should try? I have only cleaned up the crown a flake to remove a tiny nick that was there from the factory,set up the torque on the rear activeness screw at xiv in lbs,front spiral at x in lbs,any suggestions appreciated.

Try Eley. Some 452 don't similar Sk. Careful groups at 25 yards should be a fuzzy hole.

If your objective does't adapt downwards to 25 yards you may be fighting parrelax.

When you notice a ammo that shoots well play with activity screw torque till you find a setting that makes the smallest groups.

See the CZ grouping at RFC, lots of info at that place.

That'due south a really solid setup! Action commodities torque sounds light, just otherwise everything sounds great. How is the butt channel? CZ Silhouette'due south I'g familiar with had very flexible forearms that liked to flex into the barrel, so demote bags had to stay between the front activeness spiral and trigger guard. And yes, experiment with different ammunition.

It sounds like youve got a good setup. I had a 452 silhouette model with a V16 and it shot well correct out of the box. You should be shooting some ragged hole groups at 25 yds. I'one thousand concerned near what yous did to eliminate the nick on the cage. Simply most probable you demand to work on bench technique, like the location of numberless under the action spiral.

Outset shooting all your groups at 100m if y'all tin. And take notes on wind management, temperature and ammunition choice. When you're done shooting groups at 100, dial in your 25yd or 40m superlative setting and shoot at the brusk line to see how the wind effected windage setting. This will help you sympathize how wind effects 22 ballistics on a given day.

Lastly, you ought to test yourvscope's turret repeat ability by shooting box tests. If its tight, your beginning group and the last should be in the verbal aforementioned location. Dont be surprised if the box looks like a parallelogram, particularly at 100m. Principal thing is that information technology comes back to zero.

Don't even bother with groups under 100 meters when you do ammo tests. Many groups become bad between the turkeys and rams.

Set up the action screws betwixt 18-22 in lbs. You have information technology too light.

Adjust and shoot 2 groups. Then adapt once more. Shoot between l-100yds to decide settings.. Your groups will tell you what they similar.

Hey guys don't mean to hijack thread, but if stock is colonnade bedded, and floated, does the torque strings nonetheless have to be played with? Besides what well-nigh on a pharr or wooster stock that has the aforementione ? Thanks

This volition start some other fight! My ii cents is that pillar bedded rifles are much less sensitive to torque, just the they need enough to hold things together but not so much that stress is introduced into the stock or action.

Thanks, that is exactly what I've found with mine. I do tighten my forepart screw tighter than the rear. That its the merely thing that seems to make much difference.

Why exercise you use transmission fluid on your action screws?

I take never put annihilation on mine. I have never heard of doing that. I don't know of whatsoever shooter that puts whatsoever type of oil on the activeness screws of any rifle.

Ken, I am looking for responses from the pros in the know? Bringing up the torque outcome. :roll: Not simply hearsay that the screw threads should be dry, that has been handed down over the years. I periodically reset my action screw torque settings. Mayhap in that location are some gunsmiths that will chime in on dry vs lube threads before torquing.

Mechanics often use anti-seize earlier torquing bolts, but it's more common to clean and de-grease activeness bolts before torquing them.
