Hey Guys - doing some load development for my sons 6.5 Grendel (Howa Mini) and until now we have just been seating them all to Saami specs 2.250 COAL.
However, we measured the "lands" today with our comparator (to the best of our ability) and it would seem at 2.250 we are around 0.050 off the lands.
We do have a bit more room in the magazine and loading a dummy round we can squeeze 2.290 into the mag and that would put us right on 0.010 off the lands.
New rifle and we have only done our first batch of testing and so far it's been shooting ok with the best load just under an inch with my young fella shooting.
Questions - we are about to load up some more to test / verify so would you stick to the Saami COAL 2.250 and adjust seating depth later or run this test batch closer to the lands ?
The bullet testing is the 123 gr. SST over various charges of ADI 8208.
Thanks in advance.
