I went out today and did a seating test. it was at 100yrds, 6brai, only 62 rounds on the barrel before the test began, 105 hybrids and varget powder. this is the first time for me to test like this ( I have always shot short range and just kissed the rifling with the bullet of choice and it worked perfect for me) so my question is: is the 3rd picture ( .000 seating depth) the ideal seating depth for this load? the reason I am asking is because I have seen powder charge test and what appeared to me to be the obvious choice was not the right choice. any input is appreciated and thanks to all. bryant.
