[QUOTE="Grifm, post: 2052229, member: 116508"] I sent Steve an email with my results and asked for his opinion on which direction I should go. I use 48.6gr of CFE223 with the 150gr TTSX and get 2900fps. I had two nodes one at 48.6 (2900) and the other at 49.8 (2960ish) . If remember correctly I hit pressure around 50.4 (have to go look in my book). I ended up settling on the lower node, the SD/ES was lower and given everything I have read about CFE223 being extremely Temp sensitive I didn't want to be that close to pressure signs. I think CFE223 is going to end up being to slow because 50gr with the TTSX is compressed so I think that with the AHs the load is going to be super compressed well before you hit pressure. I think the problem with the 308 is going to be case capacity. I've never used it but I think Ramshot TAC is going to be the best hope. All the ball powders I've used are denser/take up less volume than stick powders in the same burn range. I called around and haven't been able to find Ramshot TAC locally. One shop does have some H322 but I think I will just hit the same point as the Benchmark and IMR8208 and run out of capacity before I hit pressure. I loaded up 4 with 47gr of Benchmark to get an idea of SD/ES. Using JBM's Trajectory calculator the 150 AH @ 3000 will be still be going 2459fps with 2027ft lbs at 300 and 2289fps with 1756ft. lbs of energy at 400yds. Which should be good for any shot I would take at a Deer or Elk. But if I can get another 100-150fps, all the better. -Matt [/QUOTE]
