zeroing

Tried to zero my Savage 110 338 Lapua at 100 yards. I have a 12x42 Night Force bench rest scope. I zeroed with a laser at 100 yd had it checked by a local shop. Problem is it shoots 24 min. to the right. Swaped scopes with my 308 goimg out today to find out if its the scope or rifle thats off...
