Good day, I have a quick question for you guys. I recently purchased a Sako 7mm Rem Mag. and I have loaded 168 GR Berger Bullets, know for the question at what range should a Guy use to see if the load is accurate or not I have been shooting at 100Yrds. Some opions would be greatly appreciated. As well a person should zero the scope to the target at what range as well.
