So what you want to do is use the factory ammo to sight your rifle in. Point of impact will be different with reloads but at least you'll be on paper
Then decide on your projectile and powder, and use a reloading chart to determine the STARTING POWDER WEIGHT. Once you've got the desired load in terms of accuracy and velocity, stick with that load and put the factory ammo away.
If you chop and change between factory ammo and reloads, you'll be lucky to hit an animal at the end of the barrel
