I agree with this, to a point. The point is that for self protection, or in this case self preservation, I believe that you shouldn't carry a firearm that you are not familiar with or that isn't proven. That takes practice, and lots of it, and that adds up quickly to your income.Lead bullets work fine in low velocity cartridges, and for higher velocities hard cast lead is recommended. I realizes that they are cheaper, but feel that what ever you decide for protection against something that wants to make a meal of you, cost should not be a factor.
I always carry a revolver with me when hunting, but not for any sort of backup. It's used as a short range alternative for when the rifle is in the pack while hiking in.
California requires copper. I use the Barnes
The theory behind using a hard cast bullet is that moderate velocity guns like handguns kill more like a muzzleloader than a high velocity rifle; you want penetration to give entrance and exit wounds. Small calibers like the 10mm need the penetration to make up for a lack of frontal area.
I've had excellent results with expanding bullets in the 454 Casull and larger. The Hornady XTP mag bullets are completely different than the standard XTPs you'd use in something like a 45 ACP or 10mm. Bullets like the Barnes XPB and the Swift A Frame pistol bullets are also very effective and offer both penetration and expansion and work very well on deer and black bear.
The last black bear that I shot went 235lbs, it was a nice bear but not huge. This bear was getting ready to den up and had stacked up about 8 inches of fat. A hollow point bullet in 8 inches of fat is not going to penetrate into the vitals due to the expansion of the hollow point. A hard cast bullet will/might give a little expansion however will hold together better to get the most penetration out of the bullet without bullet fragmentation or jacket separationI was reading a post can't seem to find it. But some one said when packing a pistol load it with hard cast bullets. I asked why ?? I suspecting that this was in case of a bear attack. But why hard cast bullets and not hollow point?
