I have been also told that the speed of the 220 swift should make up for the slower twist, but it does not seem to work out that way. Even the long 55 grain plastic tipped bullets will not shoot as well as the 50 grain. To be fair to Nosler the 60 grain partitions that I have were obtained by me when they first came out,with the results on the targets showing the bullets to be unstable at 100 yards I gave up on them. Perhaps the newer ones are better.
