(I'm only 21, so alot of times I'm not taken very seriously by people at gun shops/ranges due to my age).
I know how ya feel Bud. I started collecting/shooting around 18 (22 now) and I still get it. As far as the pricing and what not though, I'll simply put it to you the way my grandpa told me before he passed. It's one thing about loyalty, be loyal, upstanding, and honest to those who deserve it and give it back. But always remember, it's a two way street.
Those prices and the like, I'm sorry but when you walk in there, chances are all they're seeing is dollar signs. I'll be the first one to pay a little bit more for the oppurtunity to hold it in my hands, inspect it, and see how it functions, but if that means buying a Mosin I can get for 70 bucks at certain places, for $200 from the gun shop? Well I'm not that rich lol.
You say you've been pretty happy with your purchases. Go in, tell them what you told us here, let them know what you liked and what you disliked, and tell them why they'll no longer get your patronage.
When I turned 16 I got a job in the local supermarket and one of the managers told me during training something I still remember "For every one person who comes up and tells you why they will no longer come to the store, there are 10 that walk out and never come back without saying a word"
I wish you luck
