308 subsonic ballistics crack#
Please Note : Subsonic bullets are ideal for shooting through suppressors because they help reduce the sound signature and are designed to perform reliably at subsonic velocities. Subsonic bullets do not exhibit a supersonic crack making them quieter when shot through your favorite can. The ballistically engineered solid base b oat tail configuration combines with the streamlined green polymer tip for extreme long-range performance, and for easier loading. These bullets are new production and non-corrosive. The heavy jacketed base prevents bullet deformation during firing and acts as a platform for a large-diameter mushroom. 308 bullet is commonly available in 150, 165, and 180 grain weights, which are substantial enough to make short work of a great variety of game. The fully-tapered and special lead-core allows controlled expansion and optimum weight retention at all practical velocity levels. This data card system I used for the 168 grain but it was much better for the 175 grain. However, if you use this Field Density Altitude Compensator (FDAC) 308 175gr METERS it will. It will not be very helpful and when you go out to shoot past 300 yards, your data will not correlate. These flat-shooting, wind-defying bullets utilize ballistic-designed boat-tails and polymer tips to increase long-range efficiency and protect against tip damage in the magazine. Forget all of the 'free' stuff on the internet. 300 AAC Blackout and impacting at 1000 FPS (Feet Per Second), these bullets maintain 95% weight retention even after 12" of expansive penetration. These bullets deliver the accuracy, consistency and down-range punch required for clean kills in all situations. Hunters have a choice of fast expanding through to stout. Below 10gn, any such powder, be sure projectile leaves your barrel.
10gn is a useful start point to work up or down from.
30 Caliber (.308 Diameter) Subsonic 220gr Round Nose 50/Box was built for subsonic use and designed for much lower velocities than its Ballistic Tip Hunting counterparts. 308 is immensely effective across a wide range of game species. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Some other Shotgun powders are very close to AS30N, which is very close to Red Dot.
