Hello all, I recently shot my STG 58 that was built by a gent from another board about 4 years ago. Yes it was in the safe for that long unfired. I scoped it for fun and went to the range with some Nato ammo. Well after sighting in, this gun shot four three shot 100 yards groups under 2 inches and one sub 1 inch. I was shocked. Does anyone reload for this caliber and if so what brass can be used and what loads and bullet weight works best. I would really like to see what this gun could do with more premium hand made ammo. Thanks gents
