I found a single cavity c309-160-R stashed away in my closest a few weeks back and so far I've managed to shoot a few with very good results using 17 grains of BD and 20 grains of WC-820. I'm thinking about springing for a brand new 2-cavity c309-160-R in hopes that the dimensions will be similar to my 1-cavity version. I don't really care much about the nose diameter on this 'un because of its short length but I'm hoping it'll drop at least .310" on the bands in 50/50 (WW/Pb). I'd also like to buy one other Lee mold but can't decide due to the awe inspiring selection in 309-312. I can eliminate the 309-200 'cause of the long nose and I'd really like something that has the potential for mind boggling speed, although most of my ultra precision shooting (i.e., squirrel hunting) will be done at around 2000 fps.
If you'd like to share your successes with Lee boolits in fussy aught-sixes, I'd love to read about them.
Thanks,
MJ
P.S. Can anyone post the bearing and overall lengths on 309-150 and 309-170?
