Three 50 grain Triple seven pellets..Yikes. Read the directions. It is a magnum but can only take 3 50 grain pyrodex pellets. I have only worked up a load for 50 yrds but my ml likes 85 grains triple seven FFF in front of 295 grain powerbelts or 240 grain xtp sabots. I have not tried any other projecttiles but I have a bunch I will be testing.
