u/400CasesofCoors

Since these things are pretty much non existent ive decided to make my own out of 2 cut 20rd mags that will be tig welded back together mag halves are super glued for mock up

Need some advice for a newer handloader on how to reduce extreme spread ive been averaging low 40s to mid 40s across 2 different powders 2 different bullet types 107gr TMK/100gr Nosler Partition 2 different casings Nosler/Hornady and two different primers standard/magnum I've hit a wall and cant break any lower than 40s for ES the above labradar results are 107gr Sierra TMKs out of a 16.5" tube accurate 2200 powder cci 400 primers and shoot great id still like to fine tune the ES amd SD for longer range accuracy next test batch im gonna drop the powder charge .2gr as im up there in the max pressure range this string of 26 shots are pretty close to each other but then ill randomly get a high or low shot that opens the ES up I anneal every firing neck size (set to lowest possible tension and a slight crimp so seating depth doesn't change feeding from a mag) every 5 firings and then bump the shoulder back 0.002" brass is squeaky clean and chamfer the case mouth every firing
