I don't know how the smart folks do/did it; but I used to take a target/field/blunt tip; and hacksaw off all but an 1/8 of an inch of it; and then put a rubber blunt over it.
That way my stump shooting saved my aluminum arrows from wrecking too much.
If you just slip the rubber blunt on without a flat surface; the arrow can pass through the blunt; and ruin the arrow or worse.
I shoot some gamegetters once and a while; but I pretty much stick to the sticks; I like POC and like they say- wood has a 'soul'.
If your shooting metal blunts- your going to be held accountable for it on rocks and such.
I really liked the 2216 - and I went through a lot of autumn orange ones over the years
