Lee c309 113f - how deep to seat?

[ginoe]

Started casting these for plinking rounds in my 308 TC Encore 26" Blue Heavy Contour 1/10 twist barrel.

I've got some Unique powder & for starters, will try out 10grains at 50 yards. Hopefully I can find a combination that can accurately reach out to 100 yards.

Question: how deep to seat the soup can?

I've made a few gas checked rounds that reach the mid-point of the middle band (see pic)

I'm using a Lyman mold of the same sort. Plain base or gas checked, MY load is 10 grns of Green Dot. 308, 7.62x54, 7.7x58, these are the cartridges I use. This load improves my trigger pull and are a hoot to shoot. Kids love them too.
