Range time

Made a hipster load for the 300 Blackout. 130 grain round noses meant for a 30-30 levergun. Speer 2007. In my gun, they feed fine.  The lighter of the two didn't lock back one time with a Pmag, but ran fine in GI style magazines. No clue what the OAL is, I made samples that loaded in the mag properly and fed, then based the rest on those. Update- 1.90-1.91" Short bullet is short.

50 yard target. Top left, top right and bottom right 130 grain 6.8. Center is my hipster 300 BLK load. Bottom left???? Center bottom is a 30 round mag, irons, 125 grain TNT 300, 17.5 grains H110, Rem 6 1/2 primer.

 

Center- 5x2 attempts at subsonic. 200 grain Speer. The only functional loads- 12.3 grains H110. I think they were supersonic. Bottom left was 150 grain Speer Hotcores over 16.8 and 17.2 grains H110. 6 1/2 all around. 25 yards. Top left 30 rounds of the 125 grain load, irons. Top right and bottom right were the 130 grain loads, adjusting the irons L to R and up to where I want them.
