Your thoughts echo some of my own. I mentioned to him that the TC Encore should handle up to about 50,000 psi. Your suggestion that 70 grains of 2230 should be a limit, reinforces my thinking. Thanks.
On Friday past, I also fired about 20 handloads from my son's Traditions .44 mag. He registered results as I fired. That went well. Then, I also fired a few 225gr AccuBonds from my Traditions G3 in .35 Whelen. It's the load I've settled on for "come what may". Three into .67" at 100 yards from a corrected to MV of exactly 2850 fps. Formula: Rem brass, WLRM primers, 69 grains of CFE 223 at 3.45" COL.
And many "donkeys" for all you've done and still do: There's great stuff in those recent posts.
