I wish this was true but have a read of Section 5.10.

On outdoor shooting ranges where the CofF is captured by the slope of a man-made structure or topographical feature the following is to be considered:
a. where the slope is less than 56 deg ricochet is to be considered and managed,
b. where the slope exceeds 56 deg the danger area is cut off at the point where the CofF intersects the slope establishing a RDA range.

56 degrees! You will need a cliff or a bluff!
I would guess most if not nearly all target shooting done on farms won't meet this requirement.

Greetings @Gillie,
As I read it it is only the cone of fire and not the whole backstop that needs to be at 56 degrees. I have been working my way through the document. I have been looking primarily on how my Ad Hoc (Formerly known as Private Range) and I don't think complying will be any problem. Noise will be the big factor and I am onto that.
Regards Grandpamac.

That's great for you @grandpamac, but finding a natural 56 degree slope on most properties is not easy at all. You are also correct it is only the cone of fire that needs capture so if i had a target at 100m and based on a 20MIL cone of fire i would need a 4m by 4m area of slope at 56 degrees with the target placed in the center. At 300m this goes to a 12m by 12m area of slope at 56 degrees.

Lets say at 500m i only do supported rifle shooting. The cone of fire drops to 15MIL - this equates to a 15m by 15m area of slope at 56 degrees with the target placed in the center....
