Was hoping someone could give me some advice
I have a handi rifle in 223 with a dpt overbarrel on it. A few months back I zeroed it when I got the surrpressor fitted, I put 20-30 shots through it and the the point of impact changed to 8 inches to the right. So I corrected on paper and after another 30-40 shots it's done the same thing?
Doesn't make me very confident chasing the sneaky wee fallow along the river
Any thoughts?
Same brand, and weight of ammo ?
You haven't tightened the action bolts ?
Shot off a bench ?
Bit surprised the POI changed so much too.
I had an H and R Handi rifle in 223 a while back. Must say it was the most difficult rifle to develop a load for that I have ever had. It had a gunworks suppressor. I too had the drifting zero problem and would also split groups. 2-3 in one area and another 2 of to the right and high.
Between your zeros, did you pull rifle apart? I found that if i applied different torque to foreend screw it was applying different pressure point on barrel. Fixed it by doing two things.
One, I used a torque driver to ensure i did the screw up the same every time, and two, I made a thin washer and put it in the screw recess in the forend, essentially floating front portion of barrel. After that I stared to get consistent tight groups..
Good lunk with yours they are a fun rifle to have.
That will be the issue. I'll have to use that ideaQuote:

also try leaving forend alone and shooting with offside hand back towards action so its not on the wood....not ideal but eliminates the forend pressure.
Scope mounting...............
