Does increasing power increase frame flex?
My Talon SS started out bone stock, and with a couple of small tweaks, proved to be a real shooter. I should have been happy, but then I got power hungry. So I put in an 18 inch barrel, got a heavy hammer, and got my gun up to my goal of 30 ft lbs. That made me happy, until my POI began to wander. I had never experienced this with the lighter hammer and shorter barrel. It has a good scope on it – Bushnell Legend 5-15x, which has been solid since day 1. It seems that after about 12 to 15 shots, my group jumps up and left about half an inch. Could this be due to the heavier hammer torquing the frame a bit more?
Thanks,

Yep. The frame flexes right at the collar from pushing on the tank to hard.
My .308 has no issues with power and makes right around 300 fpe.
This was before I put the cover on the frame also. You can squeeze it all you want now and nothing moves.
X2 on what WOK says about using the laser to check for how frame flex manifests itself and is a real eye opener.
Changing to a heavier hammer and spring causes more jar upon firing and makes the rifles more difficult to hold, but loose bushings either to the barrel or to the frame and changing PSI can casue POI wandering.

Well, you changed the barrel (#1 issue) which means something else changed when you changed the barrel. Possibly new bushings that came with the new barrel ❓
Frame flex comes from improper shooting technique.
It occurs when you apply to much lateral pressure to the frame when shouldering the gun
Just cradle the gun lightly while shooting and goes away.
If anyone wants to see what causes it, just install a laser on the front of the frame and then zero it in with your scope.
Then look through the scope and see what causes the laser to move off the cross hair.
+1 Yes, higher power can cause problems. But not at 30 fps. Something else is going on! 😕

It sounds to me like somethings loose. Barrel bushing or top hat.
I would think frame flex would be constant. Not start after 10 – 15 shots.

Thanks for the responses guys. Looks like I need to start with those bushings for starters and then go from there.
