My first time reloading so tell me what you think
Here is the first two ladder tests I ran with my LRM today. .010 off the lands. Every half gn fro 67 gn to 73.5 gn of retumbo.

215 fed primer

180 gn hybrid

I did it at 250 yds the longest range I have close.

Brass is neck turned to .3145 with a loaded round so I used a .312 bushing in the die.

Chronographed the 67 and 73.5 loads don't have enough brass to crono one for each powder charge because of the lrm brass shortage and I have a magneto speed 3 so I did not want it to mess up the results by hanging it on the barrel for the ladder test so I just tested the top and bottom at the end.
67gn was 2770
73.5 was 3124

25.5" barrel

Slight bolt lift change at 72.5 and at at 73.5 bolt was still easy to lift but you could tell it was changing
also I don't feel I shot my best on the first ladder test that's the bottom photo
