Are you saying suppression is against the constitution or having to do the nfa "hoops" - the way you worded it it sounds like you think suppressore are against your rights...I don’t have any firearms with suppressors as I feel suppression is a violation of constitutional rights.
I use a .243, have a .223 and my favorite(which I don’t have) is 22-.250 with 1-7 to 1-8 barrel twist.
