I had my daughter shooting my 308 with 125 grain ballistic tips and trail Boss powder. That was a hoot!
For a little more power use H 4895 according to the instructions.
If you stay subsonic the noise is much less so you can run that gun anywhere from 950 fps to 2700 FPS. For that matter you can do it with any bolt gun. Some of the reduced loads are very accurate. If you run really slow, with a low case fill you may see standard deviation velocity be high. In 100 yards it may not matter that much.
I never really have understood why people compromise on flexibility and run a marginally small cartridge and then push it to the max.
Crap! Not that I would want to, but hypothetically I could buy a 264 Winchester magnum and run it for years as an everyday shooter at 6.5 creedmoor velocities. The barrel would last forever, and when I wanted to I could step it up to 3200 FPS.
Reduce loads are in my estimation, underappreciated. If you have a light handy rifle, and you hand load, there's no need for a kids gun.
