Reducing loads too far can be dangerous. I personally wouldn't go much lower than published minimum. I'm guessing a minimum load of RL17 would produce good velocity with low pressure and probably reduced recoil. If I was looking for a good reduced load, I would start with RL17.
Check out the Hodgdon Youth loads in the Data section on their site. IF there is a load listed for H-4895 then you can take it and use their 60% ruls and reduce the load using that powder.
It has worked great for me in several calibers making very accurate reduced velocity loads.
