[QUOTE="Lou270, post: 2765532, member: 5352"] This is hard to grasp for folks but the “hp” on a berger is not there for expansion or large enough to be very effective. They are very small to get as sharp and consistent an ogive as possible for max accuracy and BC. These bullets penetrate a few inches start to yaw then due to thin jacket come apart. They do not need to tumble to come apart because the jacket is so thin the nose will bend and burst apart or in some case the bullet will expand after nose breaks away but can tumble if impact velocity is low enough like any bullet. If the hollow point did something you would not see the bullet penetrate with a pencil wound for 3-5” before coming apart. The bullet would behave like any other hp and have near immediate start of expansion. The berger hunting bullets have thinner jackets to make sure they deform/fragment. The target bullets have thicker jackets so those who say the berger hunting bullets are the old target bullets are correct but when they changed/thickened the jacket on target bullets they kept the original very thin jacket on the hunting line because thickening the jacket decreased chance of bullet performing as expected (ie penetrate a ways then come apart doing lot of damage) It is counter intuitive but the berger hunting bullet does not need a thick jacket to perform as advertised. The very hard nose will help the bullet penetrate a few inches, even through bone before the bullet destabilizes in flesh and comes apart. A soft Point or hollow point/tipped bullet will start expanding and be most fully expanded a couple inches in where a berger hasnt even started yet. You are less likely to get a surface blow up with berger but more likely to get a pencil through type failure if something goes wrong. A traditional bullet then typically has some feature to stop or slow down expansion, a berger does not. Making the hp bigger MAY help at long range at the cost of making the bullet more fragile on closer shots since you are now taking a very thin core/soft bullet and adding a hollow point Lou [/QUOTE]
