Finally got some decent pictures of the 510 firing in the second rifle with the suppressor which I finished last night and tested today. It works fantastic. Rifle is very impressive and so is the 510. Tried a different powder today-H4227. At 27.1gr it was transonic, 28.5gr was just supersonic. Same loads with 2400 were right at 1000fps and N110 was about the same. Didn't get to chrono the 4227 but it looks like it might be a good powder for supersonic loading. Takes up about the same amount of space as the 2400 but seems to be getting more speed. Not a lot of space left in the case but with the 650gr API's or the 605gr APIT's we should be able to get 1200fps or so. With the 28.5gr load they would flash on impact with the ground. Slower loads only flashed when they hit hard targets.
Looking good so far and a lot of fun.
