I have a few loads that work really well, but when measuring the bullets I just got delivered - it looks like the change will be too drastic to ignore.
Goal for load: I use this to shoot F-Class 1,000 yards and I would like to get as many X's as possible.
Current loads that work well for me:
44.2 Varget seated 0.010 off the lands
44.4 Varget seated 0.010 in to the lands (20/1000 longer)
- This was with a .308 Berger 185H, Lot 4119, Average OAL: 1.426", Base-to-Lands: 0.690", Lapua brass
My new batch has an OAL of 1.453" and Base-to-Lands: 0.713"
The difference is more than the 20/1000 that I have different loads for.
- What should I consider changing?
I can't set them further out to keep the case volume constant, as that would move me from a jump to a jam.
I really don't want to remove powder and start testing all over again.
- Any rules of thumb?
