I have a mossberg 835 with a rifled barrel and I like it it shoots well killed deer I shoot a 12 gauge with a 3" copper solid slugs and it does shoot well. I saw the savage 212 and well I like the idea of having a bolt action gun. I personaly think that bolt guns are more accurate. Here is my question 12 or 20 guage? I have heard that a 20 shoots flatter and is more accurate. Is this true? What are your thoughts about 20 gauge slug vs 12 gauges slug?
