I don't cast my own but bought the book anyway...great info. I bought it because I want to load cast bullets in .44 mag for deer hunting. It has, and will, serve me well. Even if you don't cast your own, buy the book anyway...a lot of invaluable info for handloaders and/or hunters.
Veral, you've gotten some good advice here about another addition, so you probably don't need mine. But, you I'll give it anyway...ha ha.
A monthly or bi-monthly newsletter, or magazine, where you write about 1, 2 or 3 topics. You accept advertising from companies which will help offset the cost of production and pay you for your time before the product is even mailed out. That way you can mail to your database at no cost to you, stay in touch with your customers and make a little money. I have owned a magazine in the past and a company that used newsletters successfully. I'ts a great tool to increase your business and do something that you enjoy but on a better timeline.
Anyway, you do a great job here and provide us all a great service (which many would pay for) and I thank you for that.
Best wishes to you.
