need help on pattering

[tillery]

I am currently having a problem with my franchi I-12 constantly pattering to the left I am using the r-50 shim I also shoot from the right if anyone has any suggestions I would take them.

I'm not familiar with the Franchi shims.
Is the r-50 considered cast off for RH shooters?

If so, try the neutral shim or cast on shim, as you need the stock to come towards your left side more.

Thanks Tuck , Itried more cast it worked, while I was at the pattering board I also found that I was not mounting the gun propper in the pocket the gun was not kissing me on the cheek in the right spot. I have been shooting a different style stock for years , just had to adjust ,thats all.
