Reloading .300bo subs using 220 CC. Cases are fine with a genorous chamfer. After loading some are slightly out of spec not seating in gauge. Tried different seating dies same issue. Case is LC once fired converted. Thoughts??
What's up all! I recently built a 16" supressed grendel for daughter to hunt with. I'm looking for a bullet (reloading) to maximize her range. Whitetail and Mules central Nebraska.
