Sorry guys, I have not tried the NEF with the 209 carriers or with conicals yet. I have been working 8 days a week for the last month. Tomorrow is my birthday, so I took this weekend off. My kids have something secretive planned for tomorrow, so maybe by late Sunday, weather permitting. I still have to get out there after a big ole gobbler that wants to come to dinner too. Sure would be nice to be retired, but unfortunately I have several years yet to go.
I'll try to git-r-dun by Memorial Day, but no promises.
This is what 80 grains BlackMag'3 and 460 grain No Excuses does to primer carriers with Win 209 primers. I kinda suspect that BH209, also being a progressive powder may do the same thing. They do warn about not going over 350 grain bullets at the moment, but I'm sure they will do more testing before publishing pet loads.
80 gr BM'3, 460 grain No Excuses, Winchester 209 primers.
