I shot 2 50 grain Pyrodex pellets and a 295 grain Powerbelt Hollow Point and I got very poor performance on deer. Shooting at a target they shot very accurately though. My only 2 friends that still use Powerbelts are using this exact same load, and they don't find half the deer they shoot. I can't figure out why they wont switch.
Shooting the same load with a Fusion 300 grain bullet, saw awesome performance on deer. I love how these perform, but they have a price of a premium bullet, and seem to just have the design of a regular old bullet. If money was no option I'd shoot these all the time.
I've not shot a deer with one of the Gold Dot Deep Curls, but it looks like it would perform similar to the Fusions.
