So I decided to push my 260 a little and test a few things. I used some Lapua brass and started at 42.5 grains of RL16 and I am now at 45.5 grains with a 22 inch hart barrel. I used CCI 200 primers because they are a little thinner cup and show the primer flow a little earlier that 210M from my experience. I use a lab radar but it will not pick up the suppressor. I ordered a air gun mic for it (not here yet) and I was to lazy to get the OEHLER out to verify velocity but it appears the 123ELDM is running 3100FPS + based off the drops as compared too my 142 SMK load for PRS. I was just bored and wanted to try some thing new since I have 800 of these. Looks like this is a great load for 1000 yards from what little testing I have done.
Anyone play with these?
