NEW!!! Expanding on our top selling 223/5.56 SUBSONIC ammunition, we have added the 70 grain Speer SP!! Why 70 grain? Because a heavier bullet at subsonic speed limits will have more energy on target than a 55 grain bullet. $109.50 per 100 rounds Link to purchase: https://dallasreloads.com/product/223-5-56-70-grain-subsonic/This is made with once-fired LC brass, Speer 70 grian SP (soft point) @ 1030 fps in a 17". This ammo is loaded to SUBSONIC speeds for barrels from 10" to about 22" barrels. This subsonic ammo is not designed for barrels longer than 22". This ammo will NOT cycle an AR-15, but you can manually cycle the bolt. This ammo is designed for 1:9" twist or faster (1:9", 1:8". 1:7". etc). The 70 grain SP bullet is marginally stable in a 1:10" twist barrel at subsonic speeds, and should not be shot in any slower twist rate. Priced per 100 rounds. This ammo will NOT cycle an AR-15!!! It will shoot fine out of an AR-15, but you will need to manually cycle the bolt. If you are zero'd at 100 yards with normal full power supersonic 223 or 5.56 ammo, your point of impact (POI) with the subs will be about 6"-12" low at 100 yards. Priced per 100 rounds. Why use a 70 grain SP (soft point) flat base, instead of a BTHP, VLD, polymer tip or match bullet? When shooting at subsonic speeds, bullet stability becomes a huge factor for the bullet to properly stabilize and for it to shoot well. Bullet length is a major factor in how stable it is out of the muzzle. In a given twist rate (like a 1:10″ or 1:9″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer BTHP or VLD match bullet of the same weight. The 70 grain SP flat base is a much shorter bullet than a similar weight 68/69 grain BTHP designs. This allows the 70 grain SP flat base to be more stable and have the potential to be more accurate at subsonic speeds than a BTHP design. BC (ballistic coefficient) is for supersonic flight, and does not matter at subsonic speeds. Having a high BC match bullet at subsonic does not benefit the shooter at all. This is why the 70 grain SP flat base bullets work well as subsonic round! Bullet Trajectory- Distance is in Yards and drop is in inches. 25 +1.94 (high) 50 +3.51 (high) 75 +2.88 (high) 100 -0.01 (100 yard zero) 125 -5.22 (low) 150 -12.84 (low) 175 -22.92 (low) 200 -35.52 (low) Our top selling 223 subs in 55 grain SP, $99.50 per 100 rounds https://dallasreloads.com/product/2235-56-subsonic/
