Seeking light 30-06 load for bolt gun

[1tfl]

I'm looking for some load suggestions.
My son wants to shoot my Ruger rifle... just because he likes the rifle.
It's 30-06 caliber is still a little too much for him to handle.
I want to load some "light" load for him to shoot that's still accurate.
This will be for paper shooting only out to 250 yards or less.
I prefer something using 150gr bullets as I have a lot of them.

For 100 yards, some very good 150 grain bullet groups have been posted at various forums that were loaded using IMR Trail Boss. The velocity is low enough that 250 yards is asking a lot if accuracy in wind still matters, but you can try. Instructions are here. Their site lists 13.3 to 19 grains, with about 1500 fps being the high end velocity. Otherwise, Speer lists 26 to 28 grains of Accurate 5744 as reduced loads for 150 grain bullets. Those get up to 2000 fps and should make it to 250 a little less blown about.
