Ok i've searched, i got nothing.
How much feet per/sec and energy is a 75gr projectile going to lose when compared with a 16" barrel?
Thanks.

Look what I found using the ORANGE SEARCH button on the top of the page.

Thanks
note: use the search up at the top, not the other..
My 12" LMT piston using same ammo as direct gas Bushmaster 16" :
16"- 75 gr HPBT PRVI reloads w/ 21.5 TAC, AVG Velocity 2363fps
12"- 75 gr HPBT PRVI reloads w/ 21.5 TAC, AVG Velocity 2222fps
difference 141 fps, or 35.25 fps per inch between 16" and 12".
These were very light loads just trying to figure out the same thing as you were looking at. From my reading other peoples results it can run around 50fps per inch on hotter loads.
Not trying to discredit your help Iraqgunz, but that still doesn't answer his question. If anything, it just gave him more questions.
I have been searching for a while now on some hard data about how much velocity I'll be getting out of a 10.5" with Hornady 75gr. TAP in the .223 and 5.56 loadings. I can't come up with anything concrete...kinda frustrating...and trust me if I had the funds, I would do all the T&E myself (and post it for everyone else's benefit of course)
Thanks KBN.
The only reason i asked is i am trying to decide whether or not to go 556/223 or 6.8 for a 12.5 build.
I really wanted to stay 5.56/.223 and i *think* i will. I beileve a 62-75gr bullet will get the job done out to 300yds (which is the farthest i'd push it with a 12.5..if that far)
(note this is a hunting/range/maybe patrol if i ever find a job-make it through the academy, gun)
again Thanks guys.
I was under the impression that a 12.5 Noveske Crusader will chrono almost as much as a 14.5 colt barrel.
I did a search to find numbers, but only found people saying it was the same...
I would be tempted to get a 12.5 and a suppressor mount that reflexes over the barrel like an AAC MITER.
