Home Forums Hunting & Shooting Hunting Rifles 30 cal bullet test, cow femurs and newspaper part 1

Part 5 added. Enjoy.

Well friends, here is part 5. Lots of bullets tested (22 this time) and some results really surprised me. Just as a reminder, all the 30 cal and 6.5 bullets were tested with cow bones as outlined above and the 6mm bullets got deer bones.
