Just bought a few bullet varieties from Maker bullets. I got some 200gr and 125 gr, to load in 300 blackout. Has anyone loaded these up before? I have searched for load data and have found none. I assume I could probably load them similar to Barnes data as they are an all copper bullet.
If not, I will probably just start low and work up something and check velocities on the chrono. |

I assume I could probably load them similar to Barnes data as they are an all copper bullet. If not, I will probably just start low and work up something and check velocities on the chrono. OP, We are both at the same starting point with the MAKER milled copper expanding REX/T-REX bullets which are just becoming popular. So far, it looks like we are on our own for load data. I am going to try to work them up using the same propellants I used when working up the 208GR. AMAX subsonic and 125GR. TMK supersonic loads listed below. With the whitetail season coming up so soon, it may be early February before I sit down to get good data on these Maker bullets. Will post the results with the MAKER bullets as soon as I work them up and accuracy check them. The original REAPR 200GR. REX subsonic factory load used Hodgdon Lil Gun propellant from St Marks so that may be a very good option. Good luck! 300 BLK loads in #41 primed LC brass fired from a 16" RARR with 762-SD can@80F/300FT. MSL/29.92": (5) shot groups with the AMAX & TMK were right at 1"@100yds. with the propellants used. Both AA1680 & H110 propellants also functioned fine in a 9" AAC 1x7 upper on an AR15/M16 lower. 208GR. AMAX over 10.4GR. AA1680= 1044 FPS 125GR. TMK over 17.8GR. H110= 2089 FPS
