The Firing Line Forums - View Single Post - Noobie Question: How Exact Do You Need to Match Load Data?

I think the firing pin strikes were not acutally deeper on my reloads than the factory ammo. I had marked the reloads with a black Sharpie so I could identify them. I think the black ink made the firing pin strikes look deeper. Once I cleaned it off, I couldn't tell any difference from firing pin strikes on facotry ammo.

I think my first relaoding experience was a complete success! My plan now is to increase the powder charge .1 grain at a time until I get to 5.2 grains. That is the listed starting load. I will probably be happy with that for plinking.

I want to load one or two thousand .40's for practice, before moving to 10mm and gradually working up a full power load on that platform. I will buy some slower buring powder before I do that
