Anyone out there tried using IMR4227 in the 7TCU? I have a Encore 12" which I load the 140SP Sierra and played around with a few different loads starting from 15g up to 16.5g I seem to get good mixed results thinking that I have it dialed in but then I get a bit of a group variation even within the same charge. There is no load data that I can find using the IMR4227 but wonder if that powder is just too inconsistent.

You'll find 120 gr. very satisfying.
The TCU is more efficient and possibly more accurate than the Waters.

The cast bullet mold of his test the Soupcan is still available from Midsouth. If you ever do start casting that is a good one.
Mold is cheap for a 2 or 6 cavity custom.
