Went and played with my new chrono today

I bought a CED with the IR screen upgrade and all that stuff when I started ordering my reloading supplies. I needed to wait on a bipod and yesterday the GF was down south and hit the local walmart for me on the way back. (the closest walmart is about a 45 minute drive so I dont go unless I have a real reason) Anyways I figured I would test some ammo out of my 16 inch MK68 from AR performance.

It was so windy I couldnt get the target to stay on the stand so I just shot each round through the chrono into a berm. The chrono was about 12 feet from my shooting position. They are all in FPS and the average temp is 75 or so.

(I hope with Art's new powder we can step this up some)

Now I have heard how SSA has changed the combat to the tac and lowered the velocity ect ect so I figured I would test an old lot of SSA combat in the brown box, a New lot of the SSA CL that I had and the newest lot of SSA Tac loading:

So it doesnt look like at least for the OTM there isnt much difference between old Combat and new Tac load... I dont have any normal SSA OTM loads to compare however....

And last but not least I tested some of the good ol Remington 115 OTM round

Wow wonder why everyone has been working so hard to correct that screw up?

I know I should of shot 10 rounds per string but 5 seemed okay until i got home....
Is there anything else anyone wants tested?

Update:
As requested I went and shot the lighter grain offerings I have from SSA I was kinda surprised with the results..... All rounds were fired from my MK68 (16 inch barrel) and the chrono was still about 4 paces away the wind was giving me some errors but I got 5 shots of each after a while....

Looks like we dont need a combat load if we can keep these velocities up..... For some reason these rounds wanted to short stroke in my rifle, I dont know if thye powder changed or what but something was weird.

I was surprised how slow this round is going compared to the older 90 grain varmint round...
All of the 90's gave me slight issues with not locking back all the way or Short stroking.

There you guys go, let me know if you want any more info. I could do the pro hunters and the 110 accubonds....

I am going to add updated info to this post so it is all together...

I forgot I had one box of none combat loaded pro hunters and I should of tried those out but I didnt see them till I came back from the range. I may do it another day though.
