Boomstick303 Posted September 2, 2022 Share Posted September 2, 2022 3 hours ago, HOGRIDER said: I have not been to the Range for chrono testing of this particular load yet; but based on previous testing of very similar powder weights, I feel confident they will be in the 137-138PF range. Is this for the KKM barrel? I intend to actually back down my PF with the Barstow barrels I have just installed in my Legion and AXG. In initial off hand testing the accuracy seems to be the same with slow 147 gr bullets at a PF of about 130 and faster 125 gr bullets at a PF of about 135-138. Something I found super interesting is I did not get a big POI vs POA impact between the 147 gr and 125 gr bullets at 10 yds I use to see with the Sig barrels. POI seems to be the same for both loads. I intend to slow down 125 gr a little bit and test accuracy. You might want to test at some lower PF and see what happens. I intend to get into some pretty detailed testing with the new barrels in regards to accuracy with my current loaded ammo. I will report back in what I find with off the bench testing.

B585 Posted September 2, 2022 Share Posted September 2, 2022 If that’s at 25 yards, I didn’t think that was possible out of this gun. Very impressive!!! Link to comment Share on other sites More sharing options...

This friends RR shooting area has some limitations, so it's 20 or 50 yds. I am at 20 when testing there. Link to comment Share on other sites More sharing options...

Yes, this is definitely with the KKM. My initial testing was 4.4, 4.6, 4.8, and 5.0g. Per KKM's recommendations I was looking for that sweet spot of 1050-1100fps. 4.6g and 4.8g showed some definite promise and I did have earlier chrono numbers but only for the 4.8 and 5.0 loads. The 4.8g was averaging 141PF/1138fps. During this latest RR tests session, I tested 4.6, 4.7, & 4.8. My results above were at 4.7g! So again I'm guessing the chrono will result in ~137-138PF. In all honesty, the groups I've seen at anywhere from 4.5 to 4.8g would be satisfactory for many shooters. But I also want to see how the Zero 125s react to the KKM. When I have time................. Definitely looking forward to your results with the Bar-Sto! Keep me in the loop! Link to comment Share on other sites More sharing options...

HOGRIDER Posted September 18, 2022 Author Share Posted September 18, 2022 (edited) FWIW: Wanted to share another short test as I had not sighted in the MAX with this particular reload. This is at the range using my very inexpensive Caldwell plastic pistol rest. As you can imagine, it's not a real solid/stable platform to test on: https://www.caldwellshooting.com/rests/shooting-rests/the-pistolero/562771.html#start=1 But I feel my results turned out very well! The first image was, as noted, 15 yds while the second was checking out to 20 yds. I have to admit, with the sun being very bright, I was having a hard time keeping the red dot centered on the "red dot" of the test target on the 20yd results. Hope this helps............
