300 BLK SUBSONIC ROUNDS FULL
Mark your rod and push until it makes one full rotation.
300 BLK SUBSONIC ROUNDS PATCH
If you want to test your barrel, properly clear your gun and then use a cleaning rod and patch to push with the rifling. Also, David from Discreet Ballistics let me in on a little known fact – some of the Remington Model 7 and Model 700 300BLK rifles are mis-marked and actually have 1:10 rates of twist – barrels normally reserved for. A 1:5 (one turn for every five inches is preferred over a 1:10 rate of twist. To properly stabilize these long projectiles, they need to spin faster which means a higher rate of twist. Until we can get Jay at Pew Science to do a Pepsi challenge with the major ammunition manufacturers, we’ll just have to rely upon my ears.Īs a reminder, as bullet weights increase, so do bullet lengths. How much of a role is difficult to determine without the proper measuring equipment. But ammunition choice does play a role in noise reduction levels. This is not my area of expertise and I won’t pretend to understand the finer details. I wish all manufacturers would do print velocity information on the box. Any extra powder burns inside the suppressor is observed as heat, flash and noise. For the best chance at excellent suppression levels, all of that powder should be burned as the bullet crosses over the crown of the muzzle and into the suppressor. The chemical composition, the shape of the grains, fillers, and case volume all play a role in how fast the powder deflagrates (burns) inside the case and barrel after being ignited by the primer. Here’s where I wish that I was a reloader – smokeless powders come in many flavors, primary centered on burn rates. For the most part, subsonic rounds mean heavier bullets, but there are a few other variables that come into play when optimizing a subsonic round. What we don’t talk about often enough is ammo choices. Long, short, mounting systems, and more are the characteristics that will help you spend your money wisely.
As I have stated many times in the past, the perfect 300BLK silencer is the one that fits most of your intended needs. We have talked at length about 300BLK platforms and suppressors, focusing on utility, enjoyment, and of course noise reduction. SILENCER SATURDAY #203: Is All Subsonic 300 Blackout Created Equal?
