RA51,
Me again. I just started reloading the 223 REM and am using Ramshot TAC. I chose this powder because the nearest gunshop to my house carries it. Load still in development but to date have tried the following in both my Kids AR15 and my handi 223.
OAL 2.22
Taper Crimp (switching to lee factory crimp soon as the die arrives)
TAC 22.8 to 25.9 grains
Hornandy FMJ-BT 55 grain (cheapest bulk .224 bullet @ Grafs)
Rem Small Rifle Primers
Using once fired military and commerical brass. 3/4 neck size only.
All loads cycle the AR15 just fine. Not sure on the accuracy as my wife took the gun to bust clay pidgeons sitting on the 100 yard backstop. She report one shot, one pidgeon for a 20 round mag.
Have shot 19 rounds through a brand new H&R 223, 22" standard barrel. Powder in the 24.0 to 24.5 seems to work best but this is very prelimary. Got approx. 1" group on 3 of the 6 powder charges I have tried.
No signs of overpressure on any of the loads. Ramshot does not publish data for this bullet, they do list 26.0 grains as max for a 55 grn Blitz king.
Let me know if you try this powder and how it work.
thanks
