[QUOTE="Bob Wright, post: 1767609, member: 104363"] I went thru 100 rounds of Factory Nosler 140 BTs before I even put a Labradar on it. You have a great barrel, but my smith and many others here have said to "just shoot it". You should see a velocity change at 100 rounds that may move you off of an accuracy node if you find one too early. Now that your brass is fire formed and reload it at 100+ rounds you should be in a more settled place to get true data. My rifle did not shoot well with IMR 4350. With that said, RE23 is stable and easily outran H4831 and RE17 and provided a wide flat spot in velocity towards the higher end of published data for similar cartridges. I went as far as compressed powder but no pressure signs whatsoever, using a 145 Barnes LRX, Nosler brass and CCI BR 2 primers. Mine is a standard SAAMI chamber and longer monos are consuming powder space when seated at .050 off lands. I'm not a ballistics expert, but I'm getting great accuracy at 3100 fps, and never hit pressure as a compressed load. Thinking it is the smaller powder volume and a smoother pressure curve of RE23? Re23 in my 7mm RM pushes a 175 ABLR at 2920 fps and no pressure either. Brass lives a lot longer life. RE23 is very good powder and I am still a Hodgdon fan in many chamberings. [/QUOTE]
