Hello all, I have decided to take the reloading route. I have never done it and have no equipment. As of now, I am only planning to reload for my 7mm rem mag. I am looking at purchasing the RCBS Rock Chucker Supreme reloading kit. I know that I need calipers and dies. Any die recommendations? Also, are the 2 dies in many of the sets all you need? Also, is an electronic powder scale a good idea over the manual scale? As in how hard is it to get accurate with the ".1, .2," etc. measurements? Thank in advance. Excited to get into this.
