I'm set up for reloading the 140gr Hornady FTX bullet in .357 magnum. I've trimmed the cases per Hornady. That was time consuming (and expensive) as around 0.030" had to be trimmed off. I forgot the exact no.

I was setting up my seating die and descided to see how the seating plug fit the FTX bullet. The RN plug does not fit at all. It only contacts the flex tip part of the bullet. I'm not about to seat those long bullets by pushing down on that flex tip.

My 460 Mag seating plug is made to fit the 200 gr FTX flex tip bullet. Do I call RCBS and have them make a plug for me for the 357 bullet?

I could drill out the center of the seating plug slightly larger than the diameter of the flex tip, so the plug would only contact the copper jacket of the bullet?
