[QUOTE="Darryl Cassel, post: 21671, member: 34"] Hello It's hard to determine the case efficiency of the three 30s you mentioned. The illistration I used concerning the large cases was just to show the large difference in Powder capacity cases and how inefficient one can be to the other using the SAME case. The 308 Norma and 300 Win mag are both very good and very close. The 300 ultra and 300 Tomahawk are both overbore capacity cases. They are however very good cases for the LR hunter so the big efficiency situation is not THAT important to us, as I explaned. It would be hard to say which case is the BEST in any caliber you mentioned. The 284 case is versatile, the longstanding 30/06 is very good, the 270 is very good. I could go on and on but, you will know what efficient is when you start to compare several cartriges in the same bullet diameter. When you use less powder to achieve the same velocity a large case will give you, that smaller case is many times more efficient then the larger case. Most people think just because you can put more powder in a case you will get more velocity automatically. That's simply NOT true in every case.
