A Theory offered by CINDERS

[CINDERS]

Neck tensions the key BIO I said in another thread somewhere about the AMP annealer the fact some of my F Open 6.5 x 284 brass plus my wifes 308 brass is 5 years old and was work hardened after constant reloads I was getting fliers that whilst the conditions were constant were way outside the MPI of the group at all ranges.
That was the primary reason I spent a good sum of cash getting the AMP annealer and pilots for all our rifles its first outings over a few days it got a very good work out doing a 1123 cases of the different calibers we shoot on the first outings with the annealed brass in my 6.5 x 284 I dropped only 1 point.
Then at a comp not 2 weeks ago over 6-7-800m I shot 178.16/180.30 with a 60.09 at 700M so the proof is there about work hardened brass and how it can affect the neck tension I never used to crimp my 303 brass I do not run hot loads the load I have at present is 2 grains under max for the 2209 so I am heading back to that train for this episode to see what gives I may try 5 crimped ones at the end as a base to see the difference.

Anyway I am in disusions with another member here in Aus who is doing something similar and we are going to correlate what we find.

The kicker is the data is going to be what we found with our rifles and can be freely used by shooters as a guide only because the condition of their rifle may vary to ours, their location, their loading habits thats why we are stipulating the data gained is a GUIDE only, no responsibility accepted by its use.
Because I know there a people out there who like to throw spanners through spokes just to try and de-rail someones honest intentions and efforts to try and get something that will work as that's what they do I call it preening the ego that I know more than you well good on ya pity you did not try and do something similar! (Sorry for the angst but I have come across this type in life before a PKFA = Professor know F*** Alls and classify them as air thieves.).
As I said to the member it is far easier to adjust the powder load than change front sights tapping it a gnats whisker this way & that way to centralize then mucking with it to see if you are getting POA/POI with your pet load.
