Forgot I asked this last year, must be getting old, SMH

I obtained 100 rounds of Weatherby Mag and don't gave anything to shoot it in, I have a couple Magnum 111's and a few extra 3006 barrels laying around so as I see it I have two options.
1. Sell the ammo for about $30 a box.
2. Buy a reamer from grizzly for $120 and have a new hunting option.

Has anyone here attempted this? Is there anything I need to consider?

Thanks in advance,
Ninner
