I thought about Clays too, but one thing at a time. After this afternoon I found the best load with TG was 6.0 grains. Tried 6.2 and had a few flyers so I went back to 6.0 and here's what I got: Ten rounds total, SD of 10.1 fps total, average velocity 942 fps. First five fired with powder against bullet, last five fired with powder against primer. Of the last five, the three in the middle were all exactly the same at 941 fps. Powder orientation hardly made any difference at all.
I played around with seating depth with some 5.5 grain and 6.2 grain loads before this last string and ended up going to 2.875" in order to help solve a little problem of lead deposits on the outside of the necks.
Specifics are:
Rifle: Savage 111, .308 Winchester with 20" Hog Hunter barrel and ATF Form 1 silencer.
Brass: LC 08 trimmed to 2.015", chamfered, neck turned to cut halfway around the necks, Neck-sized with .335" OD bushing, expanded with .309" RCBS spud.
Primers: Federal standard rifle
Powder: Hodgdon Titegroup, 6.0 grains even.
Bullet: ACE 314-230 plain-base cast of 2 parts clip-on wheelweights, 1 part stick-on wheelweights (mine have high tin content), one part roof lead (6.5 bhn), air cooled and aged a month to ~12 bhn. Sized through a Lee .309" push-through after aging to .3098", bottom two bands lubed with SL-68.1 in a .310" H&I set in a Lyman 45.
COAL: 2.875" which puts the bullet's front band about halfway into the throat.
Put nine in 3/4" at 25 yards with one outside high making it just over an inch, but I'm pretty sure that was me not getting the front bead fully under the bull (shooting into the sun, target in full shadow).
