    Are Cowboy dies worth getting

    I have both the standard die sets and the cowboy die sets made by RCBS in 357 and 45-70. If there is a difference other than cosmetic my calipers cannot find it.

    The Cowboys dies that I own have a larger expander, and a larger seating die. The larger seater allows a larger bullet to slide up into the seating section of the die.

    Most people will never find the seating die difference without a small hole gauge or a set of .001 increment pin gages.

    I wanted another set of .38/357 dies anyway and since I cast my own, jumped on the Cowboy dies when I saw them in sale a year or so ago I got a set. They are very pretty and do the job as expected.

    As stated, the RCBS "Cowboy" dies are same as the regular RCBS dies except for the expander. For example, the standard expander for a .45 Colt is ~ .495. The Cowboy expander die comes with 2 expanders. One is labeled .452, which is actually ~ .4502" and made for jacketed bullets. The other expander is labeled as .454, which is actually .4525 and made for lead bullets.

    If you already have an M die (.45 Colt as an example), that will also measure ~ .495 but the larger RCBS expander will work in the M die and can be purchased for around $6.00.

    If you have oversized throats and want to go to a larger expander, Buffalo Arms can make whatever size you want that will fit the M die. It is about a 4 week turn-around to order one.

    If you have a Lee expander die then NOE sells the expander buttons that work in the Lee die and are in stock. Personally I much prefer the M die.

    Take into account spring back on newer brass. Personally I shoot for .003 - .005 neck tension especially when using slow powder.

    I have been reloading cast lead 30 years before cowboy dies came out. never had a problem. so I say just a p.r. trick.

    Not really.
    You can measure the dies and find definite differences. The average reloader will not care much but they are definitely different and accomadate a larger bullet in the seater that you cannot seat in the standard RCBS die. This is based on measuring multiple sets in 40-65, a set of 38-55, 32-20 and 32-40. For jacketed bullet shooters they don't do much for you.

    The really can make a difference in the 38-55. Some 38-55s have .380 to .383 groove diameters and the larger bullets required will not fit in a standard seater die.

    ^^^ Yes, the seaters and expanders are for cast bullets

    I ordered a CBY expander 45-70 (9914) made by RCBS and it measures .4555 x .463. Will not work with ny cast bullets.
