OK,
When you mounted the scope, did you use the friction tape that the millet rings provided? It is sometimes necessary for these rings. As a rule this is not necessary but its sometimes needed with these rings that's why the company includes them with it.
I am not a fan of the sites mounted ON THE scope rings. They are so close together its like your shooting a 6" barreled pistol!!! I seriously doubt you will ever be able to AFFORD

to get them sighted it!! (An attempt at humor, no offence meant)
I have shot to many hogs to count. Most with a pistol and shotgun. many with a shotgun defensively when others wounded them and they got "ornery". Let me assure you, there isn't a hog on gods green earth that has a skull tough enough to withstand a slug between the eyes.
Two come to mind, one was about 450lbs and the other closer to 300. Three of us where walking thru a swampy area looking for these particular hogs. My buddie HAPPENED to see them lying in wait up the trail about 50yrds ahead. As hard as I looked I could not see them. I had my 18" barreled H&R with peep sights and regular Rem Slugger 2 3/4" slugs. My buddie had a 30-30 with a side mounted scope. We cautiously walked forward. At about 40 yrds the big one jumped up and charged, but stopped at about 25 yards and huffed. Turned and walked back to the second one who remained on the ground. As he reached the other hog, he turned and looked at us and charged again. this time he didnt stop at 25 yrds. I hit him between the eyes at about 10 yards and he skidded to a halt mear feet in front of me. My one buddie was nothing but feet and elbows tearing down the trail in the opposite direction. (He had no gun) My other buddie was beside me. He said, wow tha...but before he could say any more, the second hog jumped up and charged. I had reloaded and was ready but this one was to be my buddies. This part was like slow motion. My buddie jumped off the trail and to a tree for a rest. All I could hear was "I CANNOT SEE HIM, I have NO SHOT" I shoot and drop the pig right on top of his partner!! Both shot thru the head dead on their feet!! I have pictures but not digital.....I'll see if I can have some files made...
Don't worry about slugs..buck shot now that is a different matter. Buck shot to the head will likely give mixed results. I would not expect it to be 100% reliable.
Good luck,
congrats on the pork!!
