Some of our old Fibbies can correct me if I'm wrong, but the "FBI Loads" I've seen have all been semi-wadcutter hollowpoints. I was actually given several boxes of them by a retired FBI firearms training officer years ago. Conventional wisdom is that the LSWCHPs usually expanded from 3" and 4" barrels, not so much from 2-inchers. Our resident adherents to the "more penetration is always better" school will tell you that SWCs are as good as SWCHPs, or better. I disagree, except when the HPs fail to expand. This has been hashed out ad nauseum in many threads, so I must add......
