Reloading Bench Time: New Caliber Adventures

[RangeHot]

I just set up my new reloading bench and started on some .300 Blackout rounds. I'm experimenting with different bullet weights and powders. Would love to hear what others are working on and any tips for this caliber.

I have loaded .223, .308 for many years but now only load pistol calibers, primarily .45 acp, .45 Colt, .38/.357. I have been loading on Dillon presses since the early 1980's and am now using a Dillon 550B progressive. I can't say enough about Dillon products and their great customer service.

Are you looking for super or sub sonic....or both?
For supersonic in AR platforms
1.) 8.3" .300 Blackout BA Hanson Pistol Length AR 15 Barrel w/ Lo Pro, Premium Series w/ 80% Omni Hybrid Lower
2.) 10.3" .300 Blackout BA Hanson Pistol Length AR 15 Barrel w/ Lo Pro, Premium Series w/ Sharps Bros. Lower
[headspace is 0.020" difference between the two rifles]

1. Sierra Varminter HP 135gr bullet with CFE BLK 20.70 grains Fed. GM205M Primer Cases were 6x fired and annealed Hornady brass at 0.040" and 0.060" jump ...good accuracy and expansion...very good for up close and personal home defense [21.50 grains of CFE BLK was really accurate for outside shooting]
2. Barnes TAC-TX 120gr bullet with CFE BLK 19.60 grs or Lil'Gun 17.80grs CCI#41 Primer Nosler Premium brass with 0.030" jump. This is a personal all around favorite for my guns. Both are sub- MOA at 100yds.

2nd Runner Up = a good load with Speer TNT HP 125gr and H110 18.20 grains as well using Fed. GM205M primers

For subs, try 220gr SMK with A1680. Cycles well suppressed and quiet as can be. Hard to beat that combo.
