This is the most easy to reload cartridge I have ever reloaded! I settled on somewhere between 41.0 and 41.5 gr RL19 with the 108 ELDs. Hot or cold, didn't matter. It's actually a starting load, but my 26 " tubes gives me 3050 to 3100fps and excellent accuracy,super low ES and SDs. if you think 2 1/2 " group at 500 yds. is accurate. This round shoots very, very flat to 1000. Not a great hunting load at long range, but steel, yes.
When I say settled on, I mean I went straight from the Harrell drop tube to case, ran the bullets into case with one stroke. Normally, I'm crazy about a tenth of a grain and make several passes to seat the bullet. This one didn't need it. I have 2 bolt guns and an AR coming in it. LOVE IT!
