Yeah, that's ok.
tell your son great job and good luck!
My two Tikkas will do the same.
One a 223 1:8, set up with the Burris FFII 3-9x40. With 65 Sierra GK or 69 SMKs over 24 grains of TAC I get one ragged hole at 100 and sub 3/4-MOA at 200.
The other a 243 Hunter with Leupold VX-3 3.5-10x40 has shown sub 1" groups at 200 with regularity with 90 gr NBTs over 43.5 of IMR 4350.
Love those guns.
