Subsonic 223 recipes 90 grain how to#

To ensure the best highest possible loading density, select the bulkiest powder with the lowest bulk density (weight/Volume).Įxtruded flake, or -tubular or -multi perforated powders, are usually the recommended types, however there are some exceptions utilizing special spherical/Ball® powders.

However, there are exceptions involving slower burning powders with excellent ignition characteristics such as our Accurate 5744® In most cases extremely fast burning Handgun/Shotgun powders are the better options. Begin at the recommended minimum/Start loads and incrementally load lower towards the subsonic range, of between 10 Fps. Use any well-known Cast Bullet Publication, such as Lyman®, Speer® etc as a guide with the above equivalent powders. Use only powders with good ignition characteristics. Warning: - Since fast burning powders are used, it results in very low loading densities Therefore the possibility of double charging is very high!! - Please take extra precautions to prevent this from occurring. Subsonic loads using standard components will not cycle high power, semi auto rifles. Therefore, it is actually a waste /moot point shooting with these designs at subsonic velocities. Projectiles with sharp pointed ogive’s do not make good subsonic projectiles becauseĮxternal and Terminal ballistics at subsonic velocities does not exploit the design features of high BC jacketed SP or HP-BT bullets. This leads to low loading densities, which might cause ignition problems.īecause the requirement is to have subsonic velocities while maintaining the best possible combustion efficiency, the velocity should be kept as close as possible to the sonic threshold for the specific conditions, preferably between 1025 Fps to 1100 Fps. Therefore faster more efficient burning powders are required. This means the combustion efficiency is not good. But others here could have told you that as well if you'd asked.The practice of down loading rifle calibers to subsonic velocity levels must be approached in a special way.Īt subsonic velocities the chamber pressure is extremely low in most rifle calibers. You should re-consider why you're here on this forum you're not going to get the validation you're looking for this way.Ībout the only accurate thing you stumbled on here is that Blue Dot is a good powder for reduced mid-velocity loads in the 223. There's a big gap between 'wanting to learn' and ' something to prove', and you're on the wrong side of that gap.

Your first post started that way and you've continued that theme the only thing you've proven to the rest of us is that you know very little about subsonic loads or how to build them effectively.

It's sad to see someone so arrogant that they can't step back and see how much more there is to learn about a topic, because they're so focused on 'proving' that they're smarter than everyone else. You've been going out of your way to prove you're not that man. Save me.Ī wise man knows to shut up when he doesn't know what he's talking about. And also tell me what to buy and how much to pay for it. Maybe next time, you tell me what is OK to like and not like. I am allowed to say I don't like trailboss right? Or has the Democrat party taken over reloading too and I can't say that or have an opinion.

Subsonic in 5.56 is almost useless as you guys know. I wanted to see how linear the progression of velocity was until it cycled the gun. So now, I learned what charges will get me subsonic with prettty much any pistol powder, since the 10 powder sampling covers almost the entire range with comparable powders.Īlso, the Blue dot going UP, had nothing to do with subsonic. I never did that test before, that was first time out with pistol powders in 5.56 cases. As you can see, I could care less about load data from manufacturers so that doesn't matter to me. Unique? 10/10.īUT, if you won't load anything except following manufacturer load data, than Trailboss is great, and I understand that, for those folks. If versatility is why you like certain powders, like why people like UNIQUE for example, then by that measure, objectively, Trailboss is the worst pistol powder you can buy. For example, 9MM it doesn't work, and also, you should not compress trailboss.

I don't like trailboss because it has 'narrow' versatility.
