A cold bore shot ( The first fired ) can be from a clean and oil'ed barrel , A fowled barrel
that has been dry patched , or a barrel that has been shot many times with out cleaning.
A clean oiley barrel normaly shoots a diffrent velocity than a fouled one , thus changing
the POI from the second and third shots if they are nessary.
I always clean and shoot one fouling and then sight in with the next 3 shots on my hunting
rifles. Then I clean and fire one fouling shot ,dry patch to remove the powder fouling (No oil)
and I'm ready to go hunting knowing that the first 2 or 3 shots will be on target.
With the stainless barrels you can hunt the hole season with out cleaning just dry patch
Some rifles do ok with out doing anything but most will change POI after cleaning for the first
Even if it is different from the first shot clean to the second as long as you are zeroed how ever you want to prepair your rifle for the first shot ( The one that counts )Is the most important.
I hope this helped
