Thread: 7mm rem mag factory ammo cds data

After some help with the leupold cds. I've just purchased a tikka t3x elite in 7mm rem mag with a dpt suppressor on it. I've got a vx3 to go on top. I'm going to be running the Hornaday proformance hunter factory ammo (162 grn i think it is ) . Is the load data off the box accurate enough for ordering a new dail cap ? The scope currently has a custom cap for a 223 and my factory one is about 9 hrs away from me.
