No, the problem with the short bullets is they don't always feed right and get pulled forward in the mag by the one above it or the BCG. Rims need to NOT have any rough spots. They get pushed to the front of the mag, bolt hits them and nose jams in the feed ramp. Don't load more than 4 in the mag so spring pressure isn't so great helps, I still get a jam once in a while. Try those 110gr half jackets - lots of jams. Always bang the mag on something hard to seat the cases against the back of the mag helps too. A proper solution would be a mag with smaller internal dimensions.
