[QUOTE="imartin, post: 1846358, member: 106328"] Doublez, Your post was reason enough for me to go back and review my loading/shooting notes on the limited experience i had with 8133. My extremely small sample of data appears to support your notion about 8133 gradually building pressure. And as it turns out, it was not that far behind Retumbo in velocity. It appears that I can get similar velocity to Retumbo by using 2 more grains of 8133. In other words in 70 grs Retumbo gets me 2900 FPS, 72 grs of 8133 gets me there too.
