I have no specifics as to exactly what the effects are, but this seems like a place to start thinking about internal ballistics.

PowderBurns Black Powder / Muzzle Loading Forum:
I see where you are coming from. Short barrel....more complete burn with fast burning powder. Less muzzle blast for sure. Velocity won't be as good as some slower powders (even in the 12" barrel). Accuracy? Probably should be pretty good.
But, if you are going to use this in short barreled gas operated semi-auto, you are going to have short recoil for sure.
Alliant 2400 wouldn't be my first choice for a short barreled 223 Rem., but if you have some on hand and want to use is in a Contender or other pistol, it should work OK with your 53gr. CCI/Speer bullets.

Just re-read your original post. What are 53 grain cci hollowpoints?
Good question. It should have read 52 grain cci/speer. Maladjusted fingers I think.

But I have had very good luck with Blue Dot, I use 12.8 grains with a Sierra 40 grain SP it was designed for the .22 hornet, gives about 2800 fps and exploasive performance on ground squirrels.
Very accurate with 3/4 in groups or less at 100 yds. This load fills the case to about 3/4 full. Fun load with very little recoil. As always work up to this carefully as shotgun/pistol powders develope preasures quickly. The most I have loaded with this bullet and powder is 13 grains.
James Calhoun has an interesting article on reduced loads for the .223 on his web site. Just punch "James Calhoun fine shooting bullets" in your search engine and it should get you there.
