[QUOTE="TMR, post: 679057, member: 5819"] Kirby, Hopefully you took no disrespect. When I had one of the 7 AM's, WC872 was the powder of choice. This was before I think you starting using Retumbo. The 7 AM is one of my favorites for sure. I totally agree that more horsepower is better and can get a guy out of a bind. Plus the 7AM cheats wind like no other. I may have to give Retumbo another try and see what happens. It does work well in all the other big 7's for sure. I did play with the STW alot. 13 barrels worth to be exact! Brass is difficult to find now a days, and it won't feed out of AI mags for my tactical customers. What I did find, is that this case design comes really close to my STW's speed with less powder.
