So I have had this 300 for about a year now and have been using a 200 and 400y zero lately, and really like it better. Less dialing. The problem is that a lof of the matches I shoot have you make half the shots at 100y, and the other half 400-1000. I also hunt regularly with it, with my shots between 100-500y. I also have my own land and play at 1k often. I'm not sure what zero I should use.

Rifle is a 300wm I built. Its a sub MOA. It sits in an AI chasis with a USO SN3 tpal

Option 1. Use 400y zero and just use hold unders for the close stuff.

Option 2. Use 400y zero and remove zero stop and dial down for close stuff.

Opion 3. Use 100y zero and deal with it. (Feels silly having a 1500y gun with a 100y zero).

Suggestions?

Hey Andrew,

Option 2 will work, but you will have to dial backwards for the under 400 yard shots. It's easier to zero at 100 yards, and not have any enviromental conditions change your POI at 400 yards. Option 3 is your most common and probably most usefull. If you have enough elevation in your scope, then go that route.

I zero all my rifles, including a 300WM, at 100 yards as from there all dialing is up. I don't have to worry about going below my zero mark.

#3 is nice, you should have time to dial adjustments at the matches, and if you want it set up with a more universal zero for hunting (say 300 yards etc.) you can just dial the scope up to 300 and leave it there. That's what I've found to work the best on my rigs that do both target and hunting duty.

I just get a zero at each 100y and write it down on a range card that is taped to the side of the rifle. I then gauge the distanct and then dial it up on the scope and shoot right on target. Works for me.
