Re: Matching Ammo - newbie question
You are on the right track. As long as you are using the same bullet and get a load that is consistent and near the same velocity, the drop data you get from the factory loads will be useful. You may need to adjust it a little for the change in velocity, but using the same bullet with comparable velocities will give you a lot of valuable data that will easily transition to a slight change in velocity with your reloads.
I'd look for loads that have around 90%-95% fill capacity and the same velocities you are seeing with the factory loads. This will get you very close.
If some is good and more is better, then too much is just right.
