(To clear up why we are using suppressed, subsonic loads, … If you want to use a case filler to use light loads with other powders, you can use either dacron fibre or corn flour. I built the rifle from the PSA kit a couple years ago. Below is a audio demonstration of supersonic and subsonic bullets shot from a Remington 700 Rifle with a Gemtech (Caliber: 7.62mm NATO / .308) Suppressor. Often times I can't hear a dude using a .308 suppressed rifle and he's less than 80 meters away. I've been using Beck Ammunition (formerly Right 2 Bear Ammo) 150 grain pointed soft point for pig hunting. A suppressor with supersonic ammunition will suppress the gun blast, but not the super sonic crack of the bullet. This powder is suited to .308 because it is made to take up lots of internal space inside the case. .account .block-orders-history .table-wrapper.orders-history .order-section-details

for centerfire rifle that can be taken apart and cleaned very easily for people that want to have more flexibility with their rifle silencer. I run 9.8gr Trail Boss with paper plate accuracy at 100yds. It's comfortable to shoot, ballistics are really close to .30-30, and is plenty quiet out of a 9" SBR with an AAC 762-SDN-6. Above pictures shows typical unsuppressed and suppressed sound signatures with bullet noises as measured 10 meters in front of the rifle and 2 meters to the side of bypassing supersonic .308 bullet fired from a FN FAL rifle. The rifle would go "pfffft" and a second later you'd hear a "crack" bounce back off the mountain .... either that, or someone WAS shooting at me {:-{. I want to create a subsonic round for my 300WM. After it happened I took the remaining rounds of that batch of rounds home and pulled the bullets and weighed the power and they were all what they were… Read more ». Conversely, using subsonic ammo in an unsuppressed gun will still result in the loud sounds of the pressurized gas, but not the supersonic crack of the bullet. The tighter twist rate enables the slow-moving bullets to gain a bit more gyroscopic stability in flight and this is a huge thing when we’re dealing with low pressures and short ranges. So which one will fare better at the same speed? Most barrels are designed with twist rates that are optimized for a specific caliber of bullet travelling at a standard velocity for that caliber. $22.95. Just my two cents. I suspect that I could indeed get a faster and better load out of the 225 ELD if I loaded the bullet longer and added more powder in the newly freed space in the case, but that would defeat the purpose of having a magazine fed rifle. I managed to group impressively at 100 yards using a Trijicon Reflex sight. I just found this today. This twist rate is common to many .308/7.62 rifles and is in my opinion the most versatile twist rate available for any .30 caliber bore. FYI, you do not have to feel pain … Is that true? Some of the most enjoyable rounds to shoot suppressed are supersonic. Not to waste a good day at the range, I fired the rest for data and received interesting results. Quick review Add to cart.308 Win 208gr A-Max SUBSONIC. The rifle I have has a 13.5” barrel with a 1:10 twist. I’m hunting with a 308 Rem 700 suppressed with an AAC can. A last suggestion for subsonic loads: don’t just start the loads high, make sure you take aim high. For this article I’ll be using .308 Win ammunition in a bolt action as my example as it is easily made subsonic and is a good cartridge to begin working with.
