Bel- if they do, you need another gun shop.
Some shops are a PITA- had one correcting how I pronounced a cartridge (I happen to know the gent that INVENTED the cartridge
Obviously, do not pick a day/time that the shop is up to it's armpits in customers (day before deer season, etc)
Would also suggest that you find a shop with a range, and offers the NRA classes. DO be sure to have a working BS detector with you- I have encountered shops where the staff did not know as much as they think they do.
Please goggle Illinois State Rifle Association, and talk with them. They are the State assoc of the NRA- they can put you in touch with some good folks.
And do not be afraid to ask questions- I have been doing this a long time, and I am still learning.
