    If you would, next time you Chrony this load could you set the Chrony at 15 feet and report back.

    My F-1 does not do well less than 12 feet

    I can do that, although I cross-checked it with another chronograph using a known load and got nearly identical values. Of course; these are $89 machines.........

    I'm impressed with those figures also. It seems to me you do your homework so, I just have to think you have a exceptionally fast bore. I believe that is a 26in barrel? With the 168gr TTSX and my Rem 700 BDL And that charge of RL22 I can expect about 3050-3100. I am kinda anxious to see if the choro at 15ft makes a difference.

    That's the conclusion I made also. The long freebore certainly has something to do with it. The barrel is actually cut down to 24" with a 2" 'brake. The barrel is a factory stainless that my gunsmith called a "phosphate" barrel. Accuracy can be problematic with this type of barrel. It took me a long time to develop a good working load for it.

    One thing I will find out also is what temperature and altitude will do to affect this load. I had a situation years ago using a 200 gr. load that failed to group (4" at 100 yd.) at 7,000 ft. (I'm at sea level). Fortunately my 168 gr. TTSX load did group well and was subsequently able to harvest a cow elk with one shot. When I got back home I shot that load again and it was back to 1/2". That's the only time I've ever experienced that phenomenon.
