You really have to shoulder them. I do not know why but the gun I have the most trouble shouldering well. I always find myself looking over the bolt handle rather than the down the barrel. Tikkas shoulder quite well for me. From a quality and accuracy standpoint they are about equal.
in 7mm rem,the xbolt hands down,26 inch barrel with less recoil then the t3,now if you said 6.5 x55 in that range go with the tikka,clips or a plenty .
