Try IMR-4064. I use it with great results in my 243. Specifically, 36.5gns for the 100gn Nosler Solid Base bullet.

I've had good luck w/ IMR-4064 as well using Sierra 100 Gr bullets.

For Nosler 100 gr PT bullets I'd try RL-22 - I have a .243 that likes 42.5 gr of RL-22 and CCI-200 primers (that load is the book max - start low and work up).

I have a Rem 788. Varget seems to work very well with
any 100 grain bullet. I don't recall the load in grains, but shoots
sub MOA. I have a 3-9X 40 Tasco.

imr 7828 100 grain PT.

IMR 7828 works for my daughters youth rifle and a 20" barrel. I'm shooting 44.0 grains IMR 7828 and getting 2700fps average velocity with a 95 gr. ballistic tip. This load works well on deer out to 200 yards and groups sub-moa at 100. Recoil is mild and pleasant to shoot. No large flash to scare the child. :grin:

Imr IMR7828, H4831, RL22 or Varget, I'd start with which ever one I had on the shelf, in that order if I had more then one, and feel pretty comfortable I'd come up with a good load. He will be fine for deer, with either bullet.
When it comes to elk, unless the conditions are VERY controlled, I'd ask that you consider something bigger just as soon as you feel your son is ready for it.
