![]() ![]() ![]() It uses a 180-200 grain bullet at about 1100 fps in many loads. ![]() If you need a comparison, consider 10mm Auto. If expanded, penetration will not be great. However, its still a 240 grainer at less than 1100 fps. There are a couple of very specialized bullets that will expand at sub speeds. The bottom line: There is NO subsonic loading, of any weight, that is a truly viable and ethical round for deer and hogs at anything much beyond 20 yards. Your muzzle velocities are 500 fps lower than that. Generally speaking, bullets like the Nosler Ballistic Tip are often recognized as some of the lightest constructed, rapidly expanding rifle bullets. Not only do you NOT have the basic physical energy needed to cleanly take deer and hogs, you are often, in most cases, using bullets well below their expansion and performance thresholds. Actually, the lowly 30-30 has roughly equivalent power and energy at 400 yards as the light subsonic load you are using at the muzzle. And the old school and antiquated 30-30 has nearly 3 times the power at the same range. Even though this is our "most powerful" option, at 100 yards you've got a round that produces a measly 500 ft/lbs of energy, or about HALF of what is generally accepted or recommended as suitable for deer. 30 cal like a suppressed 308) that still remains subsonic is a 230-240 grainer at 1100 fps. About the most "powerful" load in a 300 AAC (or any other. So a heavier bullet will give you more power. A 220 grainer going 1100 fps strikes with more power than a 150 grainer at 1100 fps. Unable to increase speed, we have only one choice: Increase the mass or weight of the bullet. So we cannot increase speed and remain subsonic to increase power. If we increase the speed of the bullet, it will not longer be subsonic, and you'll get the loud "crackkkkkkk". ![]() If its subsonic, any bullet has an absolute "speed limit" of about 1120 fps or so. Stick it in a 300 mag of some flavor, and now the its going 3200 fps, it strikes with MUCH greater power. Stick the same bullet in a 308 and drive it t0 2800 and its going to hit harder. A 150 grainer in a 30-30 is moving at 2200 fps. What we often do to increase "power" is to increase a bullet's speed. The energy and impact of your bullet is determined by two things: Speed of the bullet at impact, and the mass of the bullet. Methodical load development by Discreet Ballistics has created a system which will minimize point of impact shift allowing the shooter greater confidence when it’s time to hunt.If you re hunting anything with ANY round that is subsonic, you really need to reconsider what you are doing. The Discreet Ballistics’ two load system was conceived so that the shooter of subsonic ammunition can practice with a less costly target load, and hunt with a premium Hunting load. The Selous projectile uses state-of-the-art ballistics modeling software with the goal of maximizing stability at subsonic velocities. This load incorporates a machined copper 30 Caliber projectile (the Selous bullet) which expands at subsonic velocities above 750FPS. This round will also function with semi auto platforms, but will require manual cycling of actions. This load is intended for short barrel (<20″) bolt action rifles with 1:10 or faster twist barrels. The Discreet Ballistics 308 Win Selous Subsonic Hunting load was conceived as part of a two load system. INTENDED FOR BARRELS WITH A 1:10 OR FASTER TWIST. ![]()
