Not sure this is the right tread section for this but I have a question regarding dry firing. This is on a 110 model action if it matters any.

Is this bad for the firing pin or riffle? Is this why they sell those caps? are they required.

How do you go about dry fire practice. What type of drills can you do.

I would like to get better at my shooting fundamentals and I am not sure where to start. This may be too much of an open ended question, but i want to hear what ever you have to say regarding dry fire practice.

Thanks in advance.
