I just got my order of SubX 190 grain bullets for my 300BLK ! I had bought a 350 legend ruger ranch to load subsonic pistol bullets that would expand , but the availability of these bullets has me re thinking that . I may just sell the legend and stick with the 300 BLK. I’ve got some good loads for the black out and now that these bullets are available I’m not sure that I want to start over. here’s a picture of the bullet ,I didn’t know it was a boat tail even though I’ve shot a good many of them in factory loaded Ammunition. They retail for 34 cents each but that’s about a 1/4 the cost of the Lehigh s that I was shooting.
