Don't worry guys, part deux will soon be added. I should have enough news paper to shoot the new bullets you guys sent me pretty soon. Thanks for you patience!
How's part II coming along? lots of interest about this thread.
**Huge CGN .264 Bullet Test Result** (lots of pics!)

How's part II coming along? lots of interest about this thread.
I know this thread is long dead, but I have been reading it and had a thought.
It strikes me that another useful piece of data that can be calculated from the results that are already shown here is how consistent various bullets are. For example the 140 grain Nosler Partition and the 156 grain Lapua Mega have identical averages for expansion and % weight retention. Looking at the photos however, the Lapua seems to have very little variation between the three test bullets while the Nosler has more variation in expansion and weight retention. If the standard deviations of the averages were included then we could compare how consistent each bullet is.
I very much agree that the average expansion and weight retention is great information to have, but I would also like to know whether the bullet I use is consistent enough in its manufacturing that it performs almost identically every time or if its performance is variable.
The best part is that using the original measurements this can be calculated without having to go back to the range.
If this is too picky for some of you I'm sorry, I'm a scientist so its just part of my nature.

Does the "scientist in you" really think that an SD from a sample size of 3, especially in bullets that showed much variability, would be valid?
I agree that an SD would be very useful; but I'd think we'd need a sample size in the 10's to get anything really repeatable.

Very, very impressive, thankyou very much! Your work and Great effort time and patience is appreciated and will be beneficial to all shooters. From one to Shooter to another, Thankyou!
And if Anyone thinks they can do a better job and "armchair" this test, than go ahead and do a better one. Your work has been seen and appreciated as stated (Your work should be passed onto
one of the popular gun magaizines, obviously shooting real game would be great and would be hard to simulate as crtics may have stated, but this test is good enough on it's own).
Keep up the excellent work!

Thanks for a very good overview of a lot of bullets, Steve. It verifies why I have been using Partitions for 40+ years and had so much success with them. The TSX and TTSX bullets are the new "Kids on the block" and are impressing many, including myself. As I already mentioned on another thread, I will not live long enough to test them the way I have tested Partitions. That said, I have shot 3 or 4 game animals with them, and they seem to kill very well. One problem, I have yet to recover a bullet - all have been passthroughs. Regards, Eagleye.

BC Steve,
I am new to this forum and the first post that caught my eye was the .264 bullet performance chart you have put together. It is outstanding! I own one rifle, a model 70 featherweight in 6.5X55. I have experimented with a number of bullet and powder combinations over the years and this is what has performed best for me. For Ontario whitetail, wolf, coyote and fox I use 120grn Nosler ballistic tips. For Ontario moose and bear I use 156 grn Norma Alaska. Again your study is incredible and extremely usefull for someone who shoots the round.

BC Steve,
You are a dedicated shooter/observer for sure. The sheer number of pages in this thread in the short time it has been up would demonstrate the interest and appreciation in your posted results. Mine included.
I was wondering if there were any velocity numbers to go with this data, since manufacturers always list the optimum velocity for maximum bullet performance. Even if you never post another comment, however, your information has confirmed many of my beliefs about bullet performance and has me thinking about future choices in a significant way!
Thanks,
Brendan
