I reamed mine myself,and it took about 5 minutes on mine,and about the same on Lik2hunts.You can use the 44 mag dies,and they go from 1646 fps. to 1977fps.with the 445 in the rifle barrel. I'm getting 2166fps with the Hornady 265 gr. and over 2200 with the 240 gr. Its closer to the 444 than the 44 mag. Digger
