I have been playing with the idea of installing a choke in my shotgun. What steps do I need to take to be sure I do it right? I know the obvious answer is to take it to a gunsmith, but I take a lot of pride in doing things for myself and I am very handy with firearms. Another question I have concerns the safety on the Remington 700 rifles. A friend has had a problem with his weapon firing when he turns off the safety. He hasn't played with the trigger any and the gun won't do it all the time. I have one in 308 that is my favorite deer gun and I want to know it there is a problem with the safety and I missed the recall?
