TC's are one of the worst brands to buy when you want to shoot conicals. TC even used to tell you their rifles were designed for sabots, not conicals. Their QLA system was a poor set up and causes huge accuracy problems with conicals.
That's funny there.My Hawkin's original barrel did not have the QLA, the subsequent two they put on after I wore the barrels out did. All three shot darn good. My two in lines ,have them and they shoot darn good. The Black Diamond will not shoot maxi-balls ,but talking to TC they reccomended the Power Belts, which IMHO is a conical also. I remember they said the inlines different twist and need for a more accurately made bullet than the maxi-ball was the reason. They never told me they would not shoot conicals well and were designed for sabots. Yes,I actually talked to TC a number of times.
