Load Data Eligible SigSaur 1911
This is another upgrade I bought for my MEC 600 Jr. Mark V. I had never bought new hulls for my loads before and when I finally did I found out I was having problems getting the crimp right with them. I thought my MEC had gotten out of adjustment and went crazy trying to get it working right. Always learning something new. If you want to load new hulls, you need one of these.
