h110 for .223 ?

[Texas by God]

H110/W296 is all I use in .30Carbine and .300BO; and the upper level .41 magnum jacketed bullet loads.

Using your data source, stick to red dot or green dot.

Have you thought about trying Trailboss?

I would look real hard at red dot/promo for the loads you want.

H110 is excellent for steep loads in both 357 and 44 magnum. I agree with others here that a fast pistol powder like unique, red dot, green dot, etc. would be better for your application. These double based pistol powders do not require a filler and are usually not too position sensitive. Once you get up to slower powders like blue dot or H110/296, you'll need to use enough powder to develop enough pressure to get good ignition, and this will increase the velocity above what you're looking for. If you try using slower powders for reduced loads you'll end up blowing a lot of unburned powder out the muzzle, and your velocity spread (and accuracy) could be all over the map.

I've messed up brass using loads of W296 that were below 90% case fill with "published" loads. But, 223/556 at subsonic speeds - why not shoot 22lr instead? CMMG makes an adapter for your AR.

I really like H110/WW296 in the 22 Hornet. There is a ton of published data. I would never shoot it in 222 or 223, but I do wonder if it was all I had and could somehow make the case volume the same as the hornet what might happen.

Welp guess I'll keep that can of h110 for something else

Works real good in 410 loads.
