The 270 ball-et with 80 grains of powder shoot excellent out of my Wolverine. I have a friend that bought a Wolverine many years ago, and a box of the 270 ball-ets. It took him four to sight in and he's wasting two a year on deer. Its all he hunts with. Even his son shoots them. They are getting hard to find in stores, so if you see them, keep that in mind.
