Brad;
You can run the front part of the rest quite high. However, I have excellent results (under 1" at 25 yards with my more accurate revolvers and pistols) with resting the heel of my hands on the rest base. On the other hand, I have done well shooting with just the handgun supported, too.
You just have to try and see what works best for you.
I've been doing this for a long time and have access to a Ransom Rest. I prefer the rest pictured at the bottom of my original post.
Like any shooting, you have to do a bit of it to learn how to use the "new" equipment. I'm happy doing it like I've mentioned.
Regarding the "under 1") comment, that is using normal revolvers and pistols. Using my Contender with various barrels and calibers, I have shot indecently small targets at 100 yards. As an example, my .221 Fireball with cast bullets and 4.0 grs. of Unique will cut 1/2" groups at fifty yards. That makes for a dandy squirrel gun and general small game.
FWIW
