the lee book I have does not go into the detail for working a load up that I would like,
I have seen articles on ladder testing, some charges for other pet loads, and powder manufacturers load data as start and max
as well as factory velocities of given projectile brand and weight

the caliber in question is 223, the powder is varget, cases are LC, primers are federal and the projectiles are 77 gr sierra hpbt, hornady 68 gr hpbt, and hornady 60 gr v max

oal will be 2.260 to fit in mags

from what I can see velocities of factory loads will be near max powder loads (within .5 gr for the most part)

I have seen articles on ladder testing and there are variations in the powder weight charge increments..

the question I have is where to start on the low end of the powder charge, and what increments to go in..

I have seen most loads posted that are between .2 and .5 gr below max

I'd rather not load from the bottom charge through the middle charge if there is no real benefit of it..
I'd rather start in the middle of the charge weight and work up..

any insight would be helpful

Thanks
