One of the best buys in trimmers is the Lyman accutrimmer, which uses standard reloading shell holders and comes with a nice selection of pilots, including a .45 that will do 577/450 cases nicely. www.midwayusa.com/eproduc...mid=755364 As a note on the trimmer, in general the BP cases don't stretch out like modern smokeless rounds because BP operates at much lower pressures. The main use of my Lyman trimmer is to take out nicks on the case mouth before they turn into splits. Unless you make your own cases, a trimmer is a "nice to have" and not a "got to have."

As stated, neck sizing is a matter of adjusting the die so sizing stops before bumping back the shoulder. Depending on your chamber this may also size the body back a little, but not enough to matter. In reality what normally fails on the 577/450 is that the neck cracks, which is being sized whether just neck sizing or not. Regular annealing of the neck is the secret to long 577/450 case life. It doesn't have to be as exact science as the following link suggests, but annealing is essential. www.gun-tests.com/perform...cases.html

Depending on what loads you try there is a wide range of other materials you might need, including bees wax, carded wool, kapok, fiber cards and such. These generally can be acquired at a craft store or made yourself.
