I have very limited experience with the partitions, three deer shot and two recovered. There was not a lot of bloodshot meat but there were longer trailing jobs than I’ve experienced with “softer” bullets. Of course, the softer bullets (ballistic tips and accubonds) resulted in more bloodshot meat.
You won't find a bullet that has a much "softer" front end than a Partition except varmint style bullets.
Partition front sections are made to expand quick fast and in a hurry.
