I need a little extra length of pull on the 464, so I decided to go with a leather pad instead of rubber...... ....plus it adds a little more "western flare". I added another inch of spacer in the sleeve, so that does the trick. It's more comfy to shoot too! BTW, I mentioned in a previous post I was moving the rear peep from forward of the breech to just aft, trying to zero the sights closer to 100 yds(rather than 50). It worked great.
