Okay, so I've posted a few times about the 6.5-284 Norma I cobbled together from a Criterion Remage barrel, a trued 700 action, upgraded trigger, etc., etc.
Long story short, I was really liking the groups I got with 56.0 grains of Retumbo for both of my test bullets- the 147 ELD-M and the 124 Hammer Hunter. Both were shooting in the .2xx" at 100 yards, and both started to open up with test loads of 56.5 and 57.0 grains. I didn't chrono the 124 Hammer Hunters, but I did check speed on the 147 ELD-M and ended up at 2863 fps average over 10 shots.
I know the "golden" number is 2950 fps but that's with a 140 grain bullet, so I was questioning whether I should be content with my 147 going 2863. Well, I don't know if I am. I also REALLY wanted to give the 137 grain Hammer Hunters a try, and those came in several days ago, so I finally sat down and threw together some more test rounds. I'm going to take 0.5 grain increments from 57.5 up to 59.0 grains with the 147 ELD-M and since it's a new bullet I'm not familiar with, I'm going to start at 53.0 grains with the 137 Hammer Hunter and work up slowly to about 57.0 grains, and will stop if I see signs of pressure. I'm hoping to get to the range next weekend to see how they group and chrono.
I will say this- @RockyMtnMT makes one GOOD looking bullet in that 137 grain Hammer Hunter! I've included some pics of a loaded test round next to a test round with the 147 ELD-M. Both rounds have the bullets 0.015" off the lands. Those 137s are LOOOONG! Fortunately, I have a long action, so I have the room in my magazine. I've also included bullet side by sides of the 147 ELD-M, 137 HH, and the 124 HH for comparison.
I wish there weren't so many days between Sunday evening and Saturday morning- I need to get to the range!
