I had this same gun in the left hand model and I rapid fired an 8 shot group that could be covered with a dime. I was using 60g Hornady V-max factory ammo when I did this. I think it will shoot better than 1/2 inch. At least the one I had did.
I have a stag model 6. The seller is not kidding about the accuracy. I do not believe in three shot groups. Each section of a match is twenty shots, so that is how I check my rifles. My Stag model six will shoot 20 in a row comfortably inside of 1 MOA. That is from a cold barrel to 20 rounds in about 5 minutes, ie: real life performance.
My loads are 69 or 77 grain sierra bullets over a Varget powder.
10 rounds through it. I have another one and used the same load in both. It was swabbed between each round. I bought my frst model 6 back with a Timney trigger and a 6x Leupold target scope so I am selling this one. My other one is going to get shipped to my dad in Fl. until this NY BS is settled.
