Has anyone had problems of a mod affecting grouping.i have two tikka t3 varmints one 243 and one 223 i have a wildcat p8 .25 cal which works well on both rifles.the 223 with this mod will make 1/2" groups.however i just purchased an ASE ultra jet-z compact in .25 cal and i have only tried it on the 223 and the groups have opened up to 3".its straight on the barrel and there are no bullet marks on the inside of the mod any ideas?
