Great for jumpstarting load development - Hornady Lock-N-Load Modified Cases

This case arrived in good shape, price was reasonable as was shipping. I use these on many of my rifles, especially when I want to start developing loads for a new rifle. With these cases (and the Hornady OAL tool that uses them) I can determine exactly where a particular bullet contacts the lands and then adjust my seating depth from there. The difference being that I know my starting point from the get-go, making it easier and faster to make adjustments and taking some of the guesswork out of it. The minuscule price of a modified case is saved in components I would use up in trying to determine the distance to lands in components and/or time (if you're using the old magic marker method). I do not use these in everything I load for, but I do use it for all my bolt action guns. Hornady does make a tool with a bend in it so you can use it on lever actions, semi autos, etc., but I am not particularly concerned with milking every last thousandth out of those so I stick to shorter OAL's and just make sure they cycle well. I would definitely recommend this product (and the accompanying Hornady tool) if you are looking to establish seating depth quicker when you are developing loads for bolt action guns, whether or not you think it is worth your time to do the same for other types of platforms is up to you:
