Good point, should have added this . Laser bore sight for 25 yds ? never need to do this if shooting a 2' sq first at 25 yds. Slap the scope on and your off to the races...No rifle rest? Laser bore sight?
I start at 50yards and strap the rifle into a rest. Insert bore sight. Adjust scope to cross hairs on laser dot. Remove bore sight, fire a single round.
Adjust cross hairs to impact of 1st round and reposition rifle so cross hairs are on bullseye. Fire single round and adjust if necessary. Two more rounds to confirm.
Move target to 100 yards, aim at bullseye.
What always cracks me up is when guys sight in with cheap ass target ammo. Spring for a box of match grade ammo FFS.
Bore sight is not a must, but I think a rifle rest is. I strap it to the bench with ratchet straps.
I use the same method with irons. Once I have done this, I am pretty confident that the rifle is zeroed.
