35 Whelen

[chapelhill]

I have a CVA Apex 35 Whelen. I have had trouble getting my gun to group. I have tried several different brands of ammo some are better than others but none are very consistent. I was told that the scope base that comes with the could be flexing and causing the problem. I have Leupold rings and a zeiss conquest scope. When the scope was mounted lock tight was used. The other issue is I can't find a different base to fit the gun. Any suggestions?

Are you letting it cool after no more than 3 shots? some rifles i have sighted in i could only shoot 1 time and then let fully cool and then shoot again.

I have been told that it's the scope base, I have been told the cva apex has head space issues, and that I need a larger hinge pin.

I am not sure what step to take next

I wouldn't think its headspace issues if the rifle is firing every time you pull the trigger. If it was excessive headspace the hammer force would be driving the case forward instead of igniting the primer. If it was too little it would be hard to close the gun or not be able to at all. I'm wondring if it could be benefitted by a fix that is done to handirifles. Put a rubber o ring between the barrel and hand guard and over the handguard screw. this in effect free floats the barrel. You can also try shooting it with the handguard off to see if the handguard is the issue. When shooting the rifle off a rest, put the forward bag under the frame and not under the barrel. These tricks work on handirifles.

Thanks for the help

+1 on letting it cool. My 45-70 is the same way. If I let it cool for 5 minutes between shots I can get 3" groups at best. If I let it cool completely I can hold 1" groups pretty easy.

I got my issue fixed. The hinge pin was too loose. Had it changed now it shoots perfectly
