Has anyone out there had any experience loading this caliber? I have loaded some of the Sierra 200Grain and Hornady 220 Grain bullets that are available for it.  Does anyone know of any other bullet choices that exist?  Successful recipes?  I have used the minimal Sierra info and some of the testing done by Taffin and one other IHMSA publication.  I am just looking for any additional input that may exist.  Looking to load for both the DW and the Seville.

Thanks,

SMF

Charger, you are correct.  I am pondering a new backdrop to do a few more pics.

I have used both of those bullets in my .375 Supermag and they work well. The Hornady 220 FN is my preference. Powder of choice is H-4227, using 20-21 grains and a Fed 210M primer. This was for my Dan Wesson, but it should work as well in the Seville, just haven't shot it enough yet, but the initial outing showed good results on the steel. I would like to do some work with Lil Gun, now that I have another new .375 Supermag in the stable.

Range Timethis is what i'v come up with hornady 220gr. bullet375 win. case shortened to 1.610", cci lr primer #200, 21gr. IMR 4227 powder, with over all length of 2.075". As always reduce the powder and work your way back up. Mainley because every press, batch of powder, set of dies and primer choice can some times put you in danger. Check your self and use GoodLuckcaution always.
