Looking at the 158g Gold Dot Gel test, average expansion was .515 with 23" of penetration. Assuming no expansion from a Keith 158g SWC (1/8" less than the expanded GD) launched at 1150fps, would the penetration be much more than 23"? I don't know. I load 6.5g of Unique under a 158g Keith and keep it in camp, woods and sometimes at home for 2-legged psycho defense -- don't feel under gunned at all. In fact, I know my follow-up shots are faster than with full bore loads. If you're set on Unique and a jacketed bullet, you could always load 7.5-7.8g under a 158g XTP -- it's no slouch. Of course with Unique, if shooting in a rather confined space, everyone may die of smoke inhalation!
