Daughter Sandi just got a new Tikka compact so to the range we go. Now I'm a relic of the past and still believe in shooting in a barrel. Adjusted the length of pull to suite her and started shooting. First 15 rounds were with the old Hornaday superfomance 139 grain. Just shooting and cleaning between shoots. Rounds 15-17 using Hornaday GMX 139 grain, basically all cutting each other dead center. Raised it up 4 clicks (one inch) and 18 and 19 in same hole again dead center. Put in 2 Barnes 120 TSX BT, half an inch higher, dead center and same hold. Folks, this rifle has a 20 inch barrel and is a shooter. Very impressive and I am not a good bench shooter.
