I'm trying to work on figuring out a good zeroing point for my TA33 to match with my stockpile of Black Hills 75 grain remanunfactured ammo.  I  see they list it at 2750 fps, but I'm assuming that is for a fairly long barreled bolt gun.  My rifle is an 18" setup.  Does anyone have some chrono data?  

I actually asked this a while ago, and got a figure of 2700 for an 18" barrel, but that seems overly optimistic.

I can get a crude estimate from this thread:  Hornady Tap  It looks like an  18" barrel would be in the neighborhood of 2550-2600 with the .223 pressure TAP, which seems to be a similar load to what I'm using.

ETA: Meant to post in the ammo section––sorry.

Thanks––just what I was looking for.  Those black hills loads do seem a little hotter.
