My experience with them is similar to Stone Cold. They should come with a warning on the box that says "Danger - High Explosives". I heard, however, that the newer generation Ballistic Tips bullets are made a little tougher than the original bullets - which came in a green/red box of 100. The newer ones are in boxes of 50 and are in a black/gold box. I quit using them for big game quite awhile back, but still think they are one of the better varmint bullets.
