Charlie MacNeil, SASS #48580 1,067 Posted January 12 Share Posted January 12 (edited) I’m currently loading 110 grain Nosler Varmageddon bullets in my 300 Blackout loads but even in the best of times those are hard to get, I have found various weights of cast bullets in stock here and there on the Interweb so I’m wondering about the efficacy of loading some of the lighter weight (115 to 135 grain) bullets in 300 Blackout. Is anybody doing it. Edited January 12 by Charlie MacNeil, SASS #48580 Quote Link to post Share on other sites
Chili Ron 938 Posted January 12 Share Posted January 12 Howdy, I do know that lead bullets create dust or vapor that builds up and jams some semi auto actions. Once they start jamming cleanin em out is a lotta work. Shooting them a little once in a while probably fine. Best CR Quote Link to post Share on other sites
Raylan 6,308 Posted January 12 Share Posted January 12 Lead bullets work fine for me in 300 Blackout semi-autos, but I use coated lead bullets and I'm using heavy bullets 220 to 230 grn for subsonic loads. Can't really tell you about light lead and/or uncoated bullets. I would think that given velocities over 2,000 to 2,300 fps that leading could be an issue especially with uncoated bullets. Be interested to see feedback from anyone who's tried it before. Quote Link to post Share on other sites
Texas Joker 244 Posted January 12 Share Posted January 12 Seems like a copper gas check would both help seal and reduce lead fouling. I shoot alox tumbled cast lead in my 45 acp's and then at the end of a range session I run 1 mag of copper jacketed through them. Cleans out any noticeable lead fouling Quote Link to post Share on other sites
Pat Riot, SASS #13748 22,345 Posted January 12 Share Posted January 12 I seem to recall reading somewhere that someone tried this at 2000 FPS with hard cast lead and they got shotgun pattern accuracy and lots of lead fouling. It has been 3 or 4 years and I can’t remember where I read this. Maybe on The High Road. Quote Link to post Share on other sites
dannyd 84 Posted January 12 Share Posted January 12 I use RCBS 168 grain with a gas check in a 300 blackout bolt gun. Works out to 200 yards. Quote Link to post Share on other sites
Charlie MacNeil, SASS #48580 1,067 Posted January 12 Author Share Posted January 12 I kind of suspected that the velocity would be a bit too much for shooting cast lead, but it was worth a try. I'm always looking for something out of the ordinary to try... Quote Link to post Share on other sites
Tom Bullweed 449 Posted January 12 Share Posted January 12 I cast and load a Lee 230 grain tumble lube over Reddot or Lil'Gun for 1200-1300 fps in a short bolt gun. No leading with 5/95 tin/lead material. Cheap shooting for 75 yard plinking. I know that others do much more velocity (1600-1700) with 150 grain bullets. 1 Quote Link to post Share on other sites
Charlie MacNeil, SASS #48580 1,067 Posted January 16 Author Share Posted January 16 I've been finding 125 grain and 150 grain jacketed bullets in stock here and there on the Interweb, so I'll probably stick with those for the nonce. Thanks, folks! 1 Quote Link to post Share on other sites
