Finding first stage "Nood" made simple.
Lucky too meet up with reloading dude Vick today.
First place accurate "Nood" is + or - from the recommend factor load of each bullet for each rifle.
So in my case, a old school factory load from the stone-ages for the 180gr bullets was 2450 ft-per second.
So load the power change too best hit the feet per second based on the factory rifle they used... So if my rifle will not produce the ft-per second, then too bad.
Example might look like this :
180gr 30/06 mild ground is 2450 ft-per second, so load a string and blast away. "check grouping."
Load next 2 stings keeping everything the same same less 1 spring .5gr up @& the other .5 down.
Shoot both strings and check grouping.
Which ever group looks the best, then keep adding .5gr until the string falls apart.
Out off the 5 too 7 groups pick the tightest of them and test once more too confirm.
If this group matches the first of its kind then your onto a good thing / if not, pick the next best grouping from the mix and re-test.
Once the re-test group shows up consistent with first group, then do the .2gr + / - from that powder charge too fine tune.
Once it's fine tuned come a little simple easy test too see if the group increases above or bellow the 1/4" tightening up or spreading out.
This is with the powder change that holds the tightest group as this primer change only will improve or not the group.
Try 2 different kinds of primers for chiz's and giggles.
In most cases of doing the simple primer thing seem that a lager % of this finds that,,,
A, the primer your using is the best.
B, a different thrown into the mix primer tightened things up.
C, A person won't know until one tries.
So find tightest group by powder by .5gr fast track followed by .2gr fine tune.
Do the different primer test, now we're in line for the COL thing. Ha.
Old school Vick said too follow the factory ft-per second too find the simple easy "Nood" as the next Noods of higher ft-per second will be above that.
Start off with the factory "Nood" first, then go after the rest of the others after that.
Simple, easy fast since all cartrages of many for each caliber have a factory ft-per second, Vick suggested that it's most likely the easiest too start here since the weight of grain bullet from the factory is "normally" a proven.
It's up too us as reloaders too fine tune from there.
Learn as I go at keeping it simple.
