Ammo tests with my sbr

[Bluto]

I am kind of new to this so please, no flaying alive...

I read and re-read with great interest ironman8's excellent review of several popular ammo loads on this thread: http://m4carbine.net/showthread.php?t=112461.

This has given me inspiration to conduct a similar test using my equipment and environment. I live in a hot, humid sea-level area and am shooting through a 10.5" sbr with a 1/8 twist with and without a yhm titanium 5.56 suppressor. The ammo I plan to include in my test is:
Hornady 5.56 62 grain tap part #8125n
Hornady 5.56 75 grain bthp t2 tap part #8126n
Hornady .223 62 grain tap part #83285
Hornady .223 75 grain bthp tap part #80265

I am planning on a test similar to ironman8's that will include two pieces of drywall, but I will include some filler material inbetween to simulate insulation, posts, wiring, etc.

I am particularly curious about the differences between the 5.56 and .223 versions of the same round and the differences using my particular setup and climate. I am gravitating more towards the heavier rounds due to my twist rate, shorter barrel and suppressor. I am purposely avoiding reloads and hand loads simply because these are (relatively) easier to find.

I will borrow a chrono for these tests and will take pictures and videos as much as possible and post my results here.

I am not a professional by any means and this, my first test, is really for my own education as to what MY ideal round will be. That being said, are there any other rounds I should include? Any other variables I should attempt to account for? Anything controls I should keep constant during testing? Anything at all I should be aware of?

I will likely start in early November and any input would be greatly appreciated! Hopefully my small test will be of some use to the great group on this board!

.223 Swift 75 gr Scirocco bonded PT

Of this bunch, I have found the most praise for the 64gr Gold Dot from an accuracy standpoint. Terminally, it does pretty well, also. It easily expands at lower terminal velocities than others, also, giving near full expansion (almost double-caliber) from a 10.5" SBR out to 200 yards. I have gotten excellent accuracy out of it. The new stuff for 2012 uses nickel-plated cases.
