Blackey Cole Posted January 28, 2017 Share Posted January 28, 2017 I really like shooting the Remington 220 gr 300blackout subsonic ammo. I been having problems finding it locally and are getting enough empty brass laying around that I need to start reloading it. At one time I had the data for that load but I can't find it right now and remember the powder was a commercial blend so I would have to find something else to use in its place. That the question what are you guys using for powder in you subsonic 220. Gn ammo? Quote Link to comment Share on other sites More sharing options...
Major Art Tillery Posted January 28, 2017 Share Posted January 28, 2017 I think Hodgdon just came out with a powder, aimed at loading that round. https://www.google.com/amp/www.ammoland.com/2016/11/introducing-new-cfe-blk-from-hodgdon/amp/?client=ms-android-motorola No experience with it personally, but may give it a look?

Tinpan McGurk Posted January 28, 2017 Share Posted January 28, 2017 Try IMR 4227 works for both subsonic and supersonic or H110 works best for supersonic Tinpan McGurk Quote Link to comment Share on other sites More sharing options...

Cusz M. Dutch SASS Life 55326 Posted January 28, 2017 Share Posted January 28, 2017 using Lil'Gun. had to back off just a little from published data to get rid of the crack. Using the Lee mold for this round which might explain the increase of velocity. Quote Link to comment Share on other sites More sharing options...
Michigan Slim Posted January 28, 2017 Share Posted January 28, 2017 H110. Saw a load for TrailBoss too Quote Link to comment Share on other sites More sharing options...
Doc Tombstone, SASS #49630 Posted January 28, 2017 Share Posted January 28, 2017 (edited) been experimenting my ownself, here is what I have come up with imr4227-good for supersonic, less velocity than others h110-generally good 1680-excellent for heavier bullets-150 and up, including subsonic lil-gun-generally good according to the book the last two generate less pressure, most of my load development has been with the last three and in pistol ar haven't tried the cfe 300 blk yet Edited January 28, 2017 by Doc Tombstone, SASS #49630 Quote Link to comment Share on other sites More sharing options...
