Last week i wanted to check if a bullet would mushroom on game. At least get an idea. So, i set up some long life milk containers filled with water along with some carboard between them.
125gr bullet at abt 2700fps.
Bullet passed straight through! Bullet lost. And little sign of mushrooming.
I know wet news paper was popular once but not much of that around these days. Lol
Planning another test soon and adding some additional cardboard. Perhaps some light plywood.
Is what i did a fair test?
Any ideas, suggestions?
KISS
Not interested in mucking around with gel

I'm beginning to think perhaps similar set up but fill the milk cartons (easily obtained) with alternating cardboard and loose dirt/mud. (fill them up on the day backed up with some pine or chip board to ensure the bullet is captured. Something like some thickish plastic or 3 ply on front to simulate skin.

Yeh, Its more about confirmation.
Cup thickness is abt average for a hunting bullet.
Lead is about average BHN for a hunting bullet too.

I guess I do lean that way, I prefer a soft-point over a hollow-point bullet.

I think having an expansion initiator, like a metal or plastic tip, a ball bearing, or simply an exposed lead tip really helps with consistency compared to an open hollow point. With an open bullet whatever material (grass, mud, hair, skin, etc) is first to strike the cavity becomes your initiator, making it very random.

Cup thickness no idea never measured it . Think the CH jacket is fairly parallel inside and .021 thick near the base but the J4 Jacket is very parallel and about ,018 thick . It's for target bullets but once it is core bonded the jacket thickness is less relevant .Cup thickness is not a parameter I need to model a bullet .
