I have both the 204 and 20 practical and can't tell a dimes worth of difference in the performance and accuracy between the two other than brass for 20 P is much easier to come by. 20 Tac wouldn't be worth the trouble or the cost and making brass would be a lot more work .

A Doe walks out of the woods today and says, that is the last time I'm going to do that for Two Bucks.
