Jeff was kind enough to send me a few of his "Hammers" to give a go, if you will. I got the 200 grain screw-in models and took them for a walk today.
The biggest assets, other than the variable weights available, is the design....packs a whallop and doesn't snake under the grass or leaves. I shot them into dirt, stumps, trees and rocky ground, and didn't harm them at all. I really liked the idea of just shooting them in the pasture field and not worrying about losing them in the grass and sod. Here's some photos of my little outing.
I used them on some 2113 aluminum arrows, and my 52# Shakespeare RH 400 from 1959. I got perfect flight with them, and flight shooting them noticed a difference of about twenty yards between the Hammers and 200 grain field points. Obviously the broad end will not be as aerodynamic.
I probably shot about fifty or sixty shots through the woods and around the fields below my house. I have to say I like them better than others I have tried to date...mainly because of the broad end and weight variation. I think anyone who loves to stump shoot will enjoy having a few of these in the quiver.
Here's why I call them the Terrible Tulips...looks like some black poseys 8^).
