Changing a Shotgun's P.O.I.

[buckpro]

I turkey hunt with a 20ga SXS and had the same thing you have.
my gun was regulated very good with 1oz lead field loads. with 1.25oz lead heavy pheasant loads out of turkey chokes started to see the right barrel pattern move right and left barrel patterns move left.

POI to POA was worse with 1.5 oz of fed HVWT and even more so with TSS, the heavier the load of TSS the more exaggerated POI was off.

I followed poor country preachers method of filing for the left barrel, he does say start with a tighter choke than you want to end up with as it will open up your pattern some.
Filing did open the pattern up a bit but not by much, the pattern stayed round, some people said they got an oblong pattern after filing. I used a chain saw file, personally I wouldn't use a Dremel.

Between the filing and dropping a 1 5/8s oz load of tss to 1 7/16ths it moved the pattern so POI matched POA

for the right (close) barrel, I dropped the tss load down to 1oz of #9's and that brought POI back in line

Thanks for the input. Worst case I screw up a set a chokes. Not too worried about opening up the pattern a little, I'm not trying to shoot 50 yards.
