Have any of you shooters out there any loading info on the 223 Ackley imp or links to info

There are a lot of folks here that use .223 AI:

Do a couple fo seaches in the "Custom Rifles & Wildcats" forum, and I am sure you will find what you are looking for.

We have had real good luck with AA 2520 in the .223 AI. You need to use a drop tube to get it all in the case, but in longer barrels this powder can put the .223 AI into the low end of the .22-250 performance levels.

My accuracy load is 28.3 gr of 748 using ww brass and federal match primers pushing a 50 gr ballistic tip or vmax, both shoot to the same point of impact. Haven't chronied the load yet but the vmax wound channels have been just plain devestation on groundhogs, haven't shot one with the ballistic tip yet. I have a lb of benchmark and 3031 that I'm going try when the weather turns nice. What I did was to weigh a powder charge to the bottom of the case neck on both a 223 and 223 AI case, came up with a 10% difference in case volume and adjusted my starting load up 10%. I'd suggest doing this calculation with cases formed in your chamber after being full length sized. If you err do so on the side of caution.
