4895 and R15 would be way down on my list? I have the Ackley Improved version. I long ago decided that 100 gr. bullets satisfied all my needs, specifically the 100 gr. Ballistic Tip. In spite of all the hysteria surrounding temperature stable propellants, I get the best performance with R22, about 3400fps. Or, a full case of H4831sc might work for you, if you can find it? BB
