![]() Save the subsonic for target shooting and the wow factor at the range, and hunt with supersonic ammo. I’ve also got some of the 190 subx hand loaded supersonic and am going to try them out this season on deer/pigs. I’ve switched to the barns 110 tac-tx supersonic and have had great results. I will say that pigs react differently to suppressed supersonic shots vs regular shots and follow up shots are easier. Even subsonic the pigs run off when hit and scare the sounder, so you might as well use a supersonic bullet to begin with. There are the discrete ballistics rounds and Makers bullets that I haven’t tried, but at $1 for just the heads was a deal breaker. Sighting in the 205’s I couldn’t get them to penetrate 5/8 plywood.Īlso shot the 190 sub-x into a already dead pig and got minimal expansion in multiple areas. I used the hornady 190 sub-x and the Hornady black 205gr. Since the 190gr SMK is one of the longer BLK projectiles I set my seating die to give me the longest possible cartridge-about 2.220 and ranging up to 2.240.I wasn’t impressed with any subsonic loads honesty. This seems like a pretty big tolerance but remember that the BLK supports a wide range of projectiles that are different lengths. 6.5 Creedmoor 130gr CX PDF 6.5 PRC 130gr CX PDF 6. Occasionally, we will temporarily publish load data on this page when a bullet becomes available and is not yet listed in the latest edition of the handbook. My personal Min OAL: 2.140 to accommodate projectile length Hornady Manufacturing Company develops and publishes reloading data for the Handbook of Cartridge Reloading.The SAAMI Specs show an acceptable range of 1.78-2.260 OAL for the 300 BLK (although 190gr SMK is a long projectile and as such will require a longer min OAL than the range defined in the SAAMI spec).The standard AR-15 mag accepts cartridges up to 2.260 OAL.Here is my thought process to arrive at the OAL I set my dies to: Regarding OAL I had to experiment to find a length that fed well.

A forum thread where users share their experiences and tips on loading subsonic 300 Blackout with different bullets, powders and suppressors. Performance: This recipe successfully cycles both a carbine length upper (and gas system) with a 16″ barrel and also a 9″ pistol length upper, w/o suppressor.
