I have used it on deer and it did the job well....bought several boxes when I found them on sale for $8.00 a box.
Accuracy is fair but nothing better than the steel cased Wolf I use.
It does not feed well through an AR due to the blunt nose and feed ramp design. It also doesn't help they are 1/4" shorter than a standard 7.62X39 also adding to the feeding problem.
I still use them in the AR pistol but have never needed more then one shot on deer.
As for home protection I would NEVER use them for that due to the obvious persistent feeding issues.
They "may" feed better in an AK because the feed ramp is an open ramp design unlike the split design of an AR.
I'm really impressed with the penetration of the 22 magnum from a 3" barrel revolver.
Both of these meet FBI penetration standards. The Gold Dot had good expansion. That not a surprise it's a gold dot.
I'm surprised by the penetration of the 32acp.
With the right ammunition it can be used for self defense especially for people that are recoil sensitive.
The Colonel was in contact with Norma when he helped design the 10mm, when Norma came out with their load it was hot and if you fired it in a light weight gun you would have problems. Aluminum frames didn't hold up well to repeated firing.
The old Remington flying ash trays (200 grain HP) where a good to go defensive rounds, but 16" of penetration is good. as long as it hits vitals! Now to opening up a hollow point it's been proven that if something fills the HP it's not going to open, and a HP thats not getting above 1000 fps is really not going to open up. Might as well been shooting round nose bullets. A semi-wad cutter bullet style would make a better wound channel as it would cut flesh with it's sharp edges.
