Hodgdon has youth loads listed for H4895. You got the wrong 4895. You can reduce H4895 all the way down to 60% of the max charge.
First, find your reduced load that shoots good. Then figure out what your velocity is (or estimate it, it isn't that critical). Then enter your bullet and velocity into JBM ballistics (free online ballistic calculator).
Try to keep at least 1000 ft lb of energy out to 150 yards. This is probably not critical, 750 will probably do the job.
If you shoot a 125 grain at 2500 fps or more, you should do fine. Just like always, where you hit them matters more than what you hit them with.
I ran the numbers myself, a 125 nosler ballistic tip at 2500 fps should be effective to twice your required distance.
