I was just looking back to some notes from this load, which was several years back and I see that when running a powder, pressure ladder with RL 26, 180 eldm in 26 inch 3 groove Lilja 8 twist on Stiller action and was having bullets Not get to target when I got them above 3000 fps. I was running them for shooting gongs to 1800 yards so I wanted to see what they would do. The load I was shooting for hunting was a safe load in MY gun running 2980 with RL 26. H1000 wouln't produce this kind of velocity in my Saum. My impact velocity on that elk was 2590 fps at 5200 ft Altitude. I could see the holes in my 5.5 x22 NF scope on the side of the elk. Impacts were 3 inches in diameter. I had pictures but I deleted them because its been a few years ago and I get too many pictures of dead elk in my phone so I clear some out. They are a good bullet for thin skinned animals, and a good long range bullet, but not for me for an elk bullet. I tested them in wet newspaper bundles and they are definitly fragile and not stout enough to be a good reliable elk bullet on bone or shoulder shot. Just my experience with them .
