[QUOTE="elkaholic, post: 1013168, member: 13833"] This is not entirely uncommon. You may shoot 10 more in the same spot at the same velocity and get a baseball sized exit. The problem occurs because it is difficult for bullets with very small meplats, like Berger, to perform the same every shot! The most likely cause, in this case, probably happened because the tip was closed. Your impact velocity was PLENTY high enough for a Berger to expand! I use a .040" drill bit to clean out the tips. You will find that most are open, but some are not. This occurs because, in the tip forming process, they are squeezing a.284" diameter jacket with .014" wall thickness down to approx. .060" O.D. A lot of jacket wrinkling occurs during this process, as you can well imagine. I do the same thing with other manufactures as well (i.e. Matrix etc.) although it doesn't seem to occur as often with the Matrix. A ballistic tip bullet will always be more consistent, but not necessarily better. One positive for the Berger is that they will penetrate a little before they expand and the bt will expand immediately.............Rich [/QUOTE]
