Agreed. I can cut 1/3 MOA off of even match factory loads and it is the end users responsibility to do their research and make sure the recommended load is actually safe to use. Not to mention the cost savings of reloading.
I could tell you the best way to shave with a straight is to hold it perpendicular to your skin just above the carotid artery and begin with strong downward force in a sawing motion...bet most would not attempt this however.
If you can't tell the equivalent of this in a reloading recipe then you most likely should not be reloading ammunition in the first place.
