"If you had a lighter bullet you could start with the data for the lightest bullet you can find. Work up from there. If you have data for 85's then 70's should have less pressure with the same charge. "



Didn't realize this. I wonder if the lower in weight/grains you go the shorter, hence the jump to the lands become farther. The 85gr Sierra is .858, they sit in the case neck roughly .165 deep. OAL is 2.650. So if the bullet was made even shorter because of reduced weight then the ogive would be yet even farther from the lands hence why the selection is based at a certain weight from lightest to heaviest?

Does that make sense?

I would guess 70 - 75gr would be feasible with a normal ojive on the bullet, lighter than that you would need a bullet with more of a blunt or round nose so you have enough bearing surface as was stated by Aaron.

Yeah 70-75gr is what I want as I would just use my 22-250 beyond that.

Default short 6.5mm

Norma used to make a target/training bullet at 80 grains. I've got a bunch of them from shooters clearing their shelves and some in factory Norma ammo. The factory stuff shoots accurately at 100m and was cheaper than factory brass. Might find some of those bullets lurking around if that is a small enough bullet (and they are quite short, and round nosed and full patch).
