Was reading the Hornady 8th edition for the FTX 140 grain. It states that I need to trim the casing down to 1.25. Instead of trimming can I use 38 special brass. The brass on the 38 is 1.144. So there is a 0.106 differance. Being very new to reloading I thought I would get some advice from people who know more than I. I have read that 38 brass can't hold the pressure of the magnum and not a good idea to load it up it will work fine. Has anyone used the FTX? Has anyone done what I would like to do? If so what recipe was used? Thanks in advance for any input!
