I am not loading anything for my 5R now as I sent it back to Remington for the third time in 2 months and requested a refund. First bad Remington I ever owned, but I definitely got a dud with this one.
That being said, if you you want to shoot heavier bullets in it, the load that JohnBoy gave with 208 A-Maxes/H1000 should work fine. A lot of 5R shooters seem to like that combo.
