+2 on War Eagle's comments.
When push came to shove, I opted for alloying to achieve hardness rather than HT'ing. HT'ing is certainly viable, and to be recommended in general. I felt that there were too many variables in play to get repeatable results from one batch to the next, or even between the beginning and end of one batch, ie: melt vs. quench temps, oven temps & heat soak times, etc., etc. Then I wised up to the fact that less velocity, softer alloys, and stricter attention to bullet design and fit equaled better accuracy on paper and animals that were killed more cleanly.
I am intrigued by the "two tone" bullets you are using Von Gruff. Been meaning to delve into it, just haven't gotten around to it yet. Paper patching is another area I want explore too.
