Well I finally got my "dream gun," a Savage 220 bolt action slug gun - which will be used for hunting dear in "slug gun only" states. However, I'm wondering if anyone has sighted one of these in using 3" slugs vs. 2 3/4"? I got mine to shoot one-inch groups at 100yds, which is really something for ANY slug gun, but after 100 yards the slug is dropping 15-18 inches to reach 150 yards! I was quite surprised. After looking through the written stuff that came with the gun again, I found a card from Savage that says they recommend Remington Accutip Sabot slugs - preferably 3" - sure wish I had read that BEFORE I bought the Accutip 2 3/4" and got all sighted in. Anyone have experience with this? Especially looking to see if there will be a great improvement by switching. At $3.00 a shot I'd like to know if it's really worth it before heading to the store.
