20 Tac Prac
Sounds like you want to use the magazine, make up or borrow some 20 Tac rounds and make sure they feed at length and bullets you hope to use. If it feeds, go with the 20 tac. But either way there is so little difference between the two. Good luck sgtg
PS my 20 Tac. loves 8208 or CFE 223 CCI 450 I use 20 Tac. Hornady dies but if you have a 223 bushing die get a bushing and do the 20 Prac.
