My experience in loading 100 grain bullets for a friends m/38 Swede did not go very well. The loads didn't shoot anywhere near as well as the rifle did with heavier bullets.
My buddies 100 grain bullets were Nosler Partitions, he got fairly good penetration on pigs due to bullet construction, but those bullets were awful as far as ruining meat.
If it were me, depending on how they group, I'd use 'em for target practice or trade 'em off. Even at todays inflated prices, bullets represent a fairly small outlay of cash compared to the other costs usually associated with deer hunting.
Never forget that no matter how fine and expensive your rifle is, all it really is, is a gas pipe mounted on a stick. It's the bullet and only the bullet that does the work of killing.
