new on me
I've not seen the "expanding blunt". But.......I've shot a ton of the old Judo Points over the years.
Used to be that "stump shooting" was a highly endorsed type of practice. Might be, but I tore up and lost a bunch of arrows in the process.
The Judo did allow one to recover arrows in grass and brush, and deep leaves, usually.
I've also got a small suppley of the angled, washer looking things made by Bear that went behind a screw in broadhead, but I do not recall what they were named.
