With all the talk about how the ultra 243 does not stablize >85 grain bullets had me reluctant to even buy a box to try out. But I finally broke down and bought some ultra cheap loads (igman if your wondering) accuracy wise they weren't bad.
Here is the question if the twist was too slow they would all key hole right. Because all but one hole looks normal. I was shooting at a propped up cardboard box so it could be just a funny tear. I'll see if I still have the target if I do I'll post a picture.
