amp Posted May 26, 2015 Share Posted May 26, 2015 (edited) I took my new open gun to the range to do some chrono work this weekend. My results are below, I started low and worked my way up. But the results have me a bit uncertain. I did not expect my starting loads to make major but I did get to major PF with a lot less powder than I expected. My chrono has always been pretty accurate but maybe something is not quite right with it. Competition Electronics ProChrono Digital Chronograph is the model. Thoughts?

Adam B Posted May 26, 2015 Share Posted May 26, 2015 is your barrel nitride coated, all of mine that are tend to shoot a touch faster Link to comment Share on other sites More sharing options...

amp Posted May 26, 2015 Author Share Posted May 26, 2015 It is not, it is just the KKM that CK puts in it. Cheeley Comp and 3 holes in the bbl. Link to comment Share on other sites More sharing options...
scottlep Posted May 26, 2015 Share Posted May 26, 2015 Seems about right. I have a Phoenix Trinity built gun with a KKM barrel, Cheely comp and 2 popple holes. The major load I run is 115 Xtreme plated bullet with 7.8 grains of Autocomp loaded at 1.169". From my chrono data my Max V was 1572, Min V was 1510. Averages out to 176PF.

amp Posted May 26, 2015 Author Share Posted May 26, 2015 Sounds good, I will keep rolling with it, I have some 7.6 and 7.8 loaded up to run. It just seemed a bit low on powder to achieve the results Link to comment Share on other sites More sharing options...
jcc7x7 Posted May 27, 2015 Share Posted May 27, 2015 Run 7.4grs in my gun, STI TRUBOR barrel with a 125 MG Getting 170 PF different guns/barrels perform differently seems like you're on the right track Link to comment Share on other sites More sharing options...

lcs Posted May 27, 2015 Share Posted May 27, 2015 It is not, it is just the KKM that CK puts in it. Cheeley Comp and 3 holes in the bbl. In my experience with KKM 9 barrels, the barrels are faster than most. Link to comment Share on other sites More sharing options...
