I have been thinking about this since you first posted it TAB. I keep going into all of the legalities and internal quality control. But, that is not the question:
I believe that the business is all about marketing. What are you doing, who are you doing it for, and what makes your product worth buying?
Examples:
1. You are making ammunition for practice and general plinking; 2. You are making down loaded ammunition for games like SASS; Etc.
Focus your marketing on what you are doing, why you are doing it, and your quality.
Price? What is your cost of production, your legal and business overhead, and what is a fair profit? Next, What will the market bear? Calculate your price point two ways: 1. What is your total cost of production, and what return on investment do you want or need; and 2. What is your competition's price point, and how far below it do you want to be (and can you do this given the expenses in method #1)?
Keep in mind that every business was at one time new and unknown. Midway USA started with Larry, Brenda, and the girls sitting at the kitchen table, taking military surplus ammunition apart, cutting the brass down, and putting it back together. Your concerns about being a newbie and how you feel about it - Sometimes we get too deep in our own heads, and we think the entire market is like "me" and my small circle. It isn't! If consumers were that deep and thinking, boat makers wouldn't worry about the amount of glitter in their gel coat on bass boats. Price and packaging will probably sell 75% of your product.
Good luck!
