Thanks for all the help and replies. I have a small stash of the coveted SR4759 which was made just for this purpose. I’ve also found IMR4227 to be a good substitute. Not sure where I’ll end up velocity wise in his rifle but 2,500fps or a little more should be doable. It’s my understanding Remington uses a powder similar to 4198 in their Managed recoil loads which should give a bit more velocity but I haven’t worked with that powder nearly as much as the other 2.
It sounds like I’m on the right track with the 125 Ballistic tip!
Thanks again,
Rick
