Question for BR competitors of .22LR with CZ 457 Rifles

[nulzehb46]

Have you tried action screw tension, shooting groups at 100 yards… normally for me I’ll set mine a little tighter on the lug than the other screw 5-10# difference…
You’ll normally have 2 or more (nodes) where the groups tighten up
I start out at 5# and go up to 35-40 tops

Those last two comments are probably right down my alley. I went back to the range today-almost no wind-to check everything from Action/barrel lugs, action/stock torque, Action/Rail connection, Rail/Ring connections, ring/scope tube nuts. Then recleaned the barrel and things got about 50% better. Then I tried oiling the barrel with a patch soaked in gun oil. I shot five targets with ammo ranging from Norma Tac to SK Semi Auto and finally some Midas+. The more I shot the more I started recognizing some inconsistencies in my shooting. My last five shots in the right row of the ARA unlimited target were
all inside the center circle.

I know you've said you clean, but when you do, have you ever used a borescope? You can't see a carbon ring without one.

When I quit blaming ammo and got my act together on the bench things improved a lot
It was usually me not the ammo
Trigger pull, grip, cheek, trigger pull, and ummm trigger pull
It is the ammo but not near as often as it is the shooter in my experience
Just keep at it--get ALL of the slop and play out of your set up
Practice that trigger pull 5x more than you do now
Strive for exactly the same set up each time
Good luck--keep at it

AMEN, bench manners have ruined a ton of otherwise fine cards. Brian.
