I got rid of my '06 before these powders became available.
On a related note, I remember finding H870 for about $4/lb when H4831 was running nearly $10/lb. I tried loading some 220 MK's up in my old Win 670 '06 over a case full of H870 and lighting it off with a CCI 250.
The bullet impacted the target almost a foot low at 100 yds, and left powder granules in the barrel and through the action. I finally used the remainder of that can of H870 as lawn fertilizer about thirty years later.
