so, i'm trying to "work-down" a load for steel challenge. any comments are much appreciated.
apparently, the power-factor for this competition/league is 125, which means that since i'm shooting a 200g bullet (L SWC) that I need a minimum velocity of 675fps, which is pretty dang slow imho.
i've been shooting almost exclusively a load that is about 900 fps as my carry ammo. putting aside, for a moment, the wisdom of having this much difference in competition and carry loads, is it feasible to get a velocity this low? at the range this weekend, almost everyone commented on how "hot" my loads were, despite the fact that 900fps is about halfway between starting and max loads. i.e. not really "near" max.
the point being, everyone elses loads were much lower. but... lyman cautions that "never decrease the (starting) charge as an increase in pressure could be encountered".
so... for a 200g lead SWC and the titegroup powder, is there a good load that will put me somewhere around, say, 700 fps? the lowest listed starting load i see is 800 fps, which is 4.5g, and it has a max of 1000 fps over 5.9g.
I figured I would start with 4.0g but before I do, is this safe? as much loading as I've done, this is the first time I've ever had a desire to go below a starting load.
