Yep I want to know seating depth before powder charge, so if I end up going all the way to a oal jammed into the lands, i dont have to then lower my powder charge if i am running at near max.
4-shot groups at 100, sorry was as far as i could get this weekend
Not trimmed, not weight sorted, i was in a hurry so i just FL resized and loaded em up.
2nd Group is .020 off lands and 42.5g imr-4064
Measurements were as good as i could get them might be off a tad but meh close i think. Paper tears funny when its just hanging on a frame.
I had another group that looked and measured just about like the .020 jump group except it was .010 off the lands, it looked prettier so I decided i am going to work with .010 jump and see what i can come up with. If it isnt consistent enough ill just go to the .020 dont know why .015 and .025 jump didnt work out very good seems odd to me that the gun would like .010 and .020 jump with SMK but nothing in between.
