I've successfully used Xtreme's plated 165 gr RN bullet, and the velocity was ok, but they were too hard to represent anything I wanted in a penetration test in wet pulp. I even 'modified' them by flattening the tip and drilling a hollow point in them. I shot them into a stack of copy paper (had nothing else). Penetration was good but only one shot out of 8 shots 'expanded', which was more like the mangled end got a half inch in diameter. So I'm getting there slowly, but didn't realize how many problems would have to be worked out.
Also, I'd like to try them at maximum COAL, for obvioius reasons, but getting them to feed is a bear.
