Hi all, I am new to the forum and a fairly new air rifle owner. I have recently become aware of slugs for air rifles. Since my barrel is not a dedicated slug barrel, is it silly for me to shoot slugs out of my gun? Will they be less accurate or harmful to my gun? I have the .22 caliber model and I have seen some slugs advertised as .217 caliber and .218 caliber, which one should I buy? Thank you for any info, I apologize if these are stupid questions.
