I'm having such issues with seating bullets for my AR in .223 Wylde. I'm getting variances of up to .010" and I believe it's due to how the bullets are being deformed by the seating die. Ive tried three different dies, RCBS, Lee, and Now my Forster Micrometer seating die. I tried using the hot glue method and that didn't work, the glue wouldn't stay in the die. Then I put some of the steel/putty type epoxy in and it worked great for a while, but it eventually disintegrated and I was right back where I started. I'm open to any ideas, or maybe I'm just overthinking this and it's no big deal. I've been thinking of taking some valve grinding compound and jigging up the seating stem and putting a bullet in a drill press and just using this to grind the seating stem to a better fitting shape. But this method worries me about keeping it concentric and not ruining the seating stem.
