my first attempt at the challenge
Thought this was going to be easy with my "new to me" 6 mm ppc. (not so much)



The gun is a tight neck 6mm ppc with heavy stainless fluted barrel, don't know the manufacturer. It is a glue in to the stock, 2 ounce jewel trigger, 36 fixed power Baush and Lomb scope.
First picture is my first target ever with a generic load I made up, boy was I excited, .284 5 shot group in November of last year.
Last picture is from November when I was testing various charges, best 5 shot group was .284 with 26 grains of H322 and Berger 68 grain match moly coat bullets and worst was .625 with 25.6 grains of H322 and Berger 68 garain match moly bullets. seating depth is what the dies were set at when I recieved them with the rifle, appears to be a couple thou off the lands but haven't verified that yet just going by the barrel chamber sample that was done I think with the same reamer as the rifle that came with the gun, when I insert a loaded round into the cutout I can see that it almost touches the lands.
Once I settled on 26 grains I was getting groups between .206 and .392 in November and December.
Now for the part that really sucks. Loaded enough rounds to shoot the challenge with 10 extra as I have been having some fail to fire issues and need to go to the 205 primers as my remington bench rest ones seem to be too hard. Anyway as you can see on the second target I missed out by .011 (group was .511) First measured it as .497 but when I rechecked all the measurements I was off by .014 somehow.
Best .257, worst .511, average .4178.
What I can't figure out is how I could get the groups I did before in the cold miserable weather and when I get a good day with very little wind, light mirage, I got worst groups than when I started!! Now for the excuses, I didn't read the wind, shot 50 rounds of 44 mag and 50 rounds of 357 mag then went directly to the rifle range 30 feet away to do my "precision shooting"
I think though that I am going to go back to the hotter loads that I used to use in my old Sako single shot and load up in the 28 grain range of H322, will see how that does.
Just realised the last picture is pretty poor, hope these ones are better!
