Question for the very knowledgeable community here: I am shooting a .224 Valkyrie in a remage setup that has very good potential, I am having issues with neck tension something terrible and I’m starting to get discouraged with it all. Here is my process on reloading: 1-Clean brass 2-Anneal with a Annie annealer 3-Size with frorester co-ax and a forester FL die with a without the recapping pin/rod 4-Trim, debur/chamfer 5-Run a mandrel for final neck size I am using starline brass as that is the best brass to date for this cartridge. I have tried loads without the neck turned and now I have neck turned the brass that I am using at this point same issues. I hunt with this gun and shoot long range “recreationally” at targets at 600+ yrds and a 20fps gain in velocity will throw me off more than a foot almost(depending on exact range), I have narrowed it down to neck tension as I can feel the difference when mandrel sizing and I mark those pieces of brass and they always have a higher velocity. Mandrel sizing the brass is when I can feel what piece is more “grabby” and what is not and I have now been trying to sort the brass according to this “feel”, but it is still an issue. Is it the quality of the brass or am I missing something here.....please ask any questions that may help you understand as sometimes when typing I don’t always remember every detail.
