My question ; what is the best method of reaming the neck. I am loading for a Zastava m57, basically a Tokarev 33. I am waiting on some 90 grain, .309 bullets from midway. I have read some of the brass will not need to be reamed. I have yet to trim the brass, resize and annealing the necks. When i measure it, i might not have to ream, but if i do, whats the best way without buying a reamer?
