Im in the process of designing a drafting table attachment for my reloading bench. I thought I'd share my idea. I like to make my own load development targets using white poster board. I write on down the left side. load data. powder, bullet, primer etc. all the common specs. then across the top ill make 4 or 5 rows of the variables. ex. seating depths or powder weights. poster board is super easy to see impacts and you can cut out the groups that stand out and tape them with Scotch tap to the back of index cards if you want. ill post pics to give better ideas of what I'm saying.
