No issues whatsoever, ran flawless in both my 2011 limited guns - fed smooth - the recoil impulse seems very soft (not snappy) to me, which I like - also it chrono'd at the advertised 170-171 PF out of my 5"
Have used Atlanta arms with no issues but have recently tried these from super vel and like the price point better

Says $75 and in stock in a couple of colors
So I had similar issue with "bullet straightness" going into the case with the standard Dillon seating die. I switched to a Redding competition seating die and problem went away. Its design seems to make the bullet go in straighter
