yes.Copy that.
Final question..
When I go to re-chrono, should I wait enough time between each individual shot to allow for the barrel to cool?
Thank you for all of your insight.
Point of aim/impact and velocity usually change as barrel heats up, some rifles can shoot 2 to 4 rounds between cooling with the last shot having a slightly different POI, thats your temp limit... my guess is a 300WM heats up pretty fast.
If for hunting you want a cold bore zero and chrono readings for best ballistic estimations. Do the work up front and you'll have more precise ballistic data to use in the field past your zero distance. After that you'll learn what your rifle gives in changes in point of impact after 2 or 3 consecutive rounds so you know in the field what practical results you will get in the (hopefully) rare chance you need more than 2 rounds to fill a tag.
