![]() IF there is a stuck bullet waiting in the bore, the next shot is going to be more than a surprise. Then you have to manually eject the fired case and rack the action to load a full power round. As suppressed subsonics are freakin quiet, in a time of stress it may be difficult to notice a squib round. You are then taking a chance by shooting a subsonic round through a potentially dirty barrel, which can cause the bullet to stick in the bore. To switch from one ammo to another you have to rack the action and eject the live round, which then has to be picked up. Quick, versitile, nothing extra to buy, nothing to convert. You put the original mag back in and you now have full powered ammo. You switch mags (to a mag loaded with subsonic ammo) and fire that shot. You need want to fire A shot that absolutely has to be as quiet as possible. Use them at your own risk - your mileage may vary. Make sure you know what you're doing with reloading before trying these. I probably need to reduce it to 5.3 grains or so.Īll of these were shot in my Savage 10FP with 22" 1:9 barrel using a YHM 5.56 Phantom suppressor. I did some experimenting and found some other successful 223 loads, as follows: The load fizzled and I had a stuck bullet. I switched to CCI Benchrest primers - DON'T DO THIS. I tried this recipe using some Sierra 55 gr soft point boat tails and it worked fine. I called Hodgdon, and sure enough, they had some suggestions. This is why the 55 grain SP flat base bullets work well as subsonic round!īullet Trajectory- Distance is in Yards and drop is in inches.The Accurate S1250 subsonic 223 loads have been discussed before, but I had not seen many other recipes. Having a high BC bullet at subsonic does not benefit the shooter at all. BC (ballistic coefficient) is for supersonic flight, and does not matter at subsonic speeds. This allows the 55 grain SP flat base to be more stable and have the potential to be more accurate at subsonic speeds than a BTHP design. ![]() The 55 grain SP flat base is a much shorter bullet than a similar weight 55 V-max or BTHP design. 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. Bullet length is a major factor in how stable it is out of the muzzle. Why use a 55 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. 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. 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. The 55 grain SP bullet is marginally stable in a 1:12″ twist barrel at subsonic speeds, and should not be shot in any slower twist rate. If you have a 1:12″ twist, you will need to check bullet stability first before shooting through a suppressor. This ammo will NOT cycle an AR-15!! This ammo is designed for 1:10″ twist or faster (1:9″, 1:8″. This subsonic ammo is not designed for barrels longer than 24″. This ammo is loaded to SUBSONIC speeds for barrels from 10″ to about 22″ barrels. Once-fired LC brass, Hornady 55 grain SP (soft point) 1030 fps.
