So further to my past queries on excess pressure signs on primers.
I was up at the range this AM. I had backed off my past load of 53 Gr of RL19 behind a 160 AB to 52 grains, and I observed the following:
On the left is a factory 160 Gr. TBT, the next 3 are from my 52 gr RL19, then the last 2 on the right are from 52 gr RL22, 160 Gr AB.
My feelings on it are that the third from left has some flattening, and the 2 on the right have the same.
Any thoughts on this?
Both the RL19 and the 22 loads were shooting fantastically. 1" group with 6 shots. Easy to chamber, easy to unload.
Now my handloads are loaded longer than standard COAL to fit my chamber better as per the Nosler manual. I wonder if the excess pressures would be resolved by shortening my COAL? The Federal TBT load is actually under COAL, but still shoots very well.
Thanks again for the sage advice and tips.
