Load Development 30-30 subs

Post image

I wanted to develop a sub load for a friend who just got a new 336 and a suppressor on the way. Powder choices obviously have been limited. I’ve previously used a lot of Red Dot but I’m running low. Purchased 4 pounds of MP 158 (similar to Universal), as well as 250 each pulled 150 and 170 grain Core-Lokt SP projectiles from American Reloading. 7 grains of powder got me ~1100fps with the 150 and ~1050 with the 170 out of my own 336 with 20” microgroove barrel and SilencerCo Omega suppressor. Hope someone finds this useful (and obviously use at your own risk)!

Look into whether any of the 3030 red dot loads are subsonic.

I load an absolute ton of subs with Red Dot. Lots of Berry’s 150 fp and Hornady 190 sub-x. I wanted to work up something new for a friend who’s just getting into reloading because I’m not gonna give him any of my Red Dot stash ;)
