DodgeNerd Posted June 19, 2020 Share Posted June 19, 2020 So I was able to try 200rds or so 9mm tc 147gr BBI, 3.05gn sport pistol, 1.09oal with a shadow 2. I havent crono d these, but started with 2.9gn SP, 1.09 OAL that got me 126pf, (I only figured I need 3gn to get me through the day). I'm leading pretty good, I believe my crimps are .378ish, and I am using a NOE expander, i do not see any shaved bullets when loaded. Thoughts?

Farmer Posted June 19, 2020 Share Posted June 19, 2020 Coated or just lubed? Bevel base, hard cast? Bevel base with regular lube will lead more than a flat base and if they’re hard that makes it worse. Try upping the charge a bit to see if it helps. May not be obturating enough to fill the bore. Also make sure the brass isn’t squeezing the bullet down smaller when seating them. Some brass has more taper than others. Hot powders can be a problem too.

DodgeNerd Posted June 19, 2020 Author Share Posted June 19, 2020 Coated, FP* https://shop.blackbulletsinternational.com/9-147gr-500-9-147-500QTY.htm I will try to pull a bullet or too to see if it's getting sized down, using a Lee FCD btw. I didnt think sport pistol was hot. Maybe I'll bring it up too 3.2 and see what happens. Link to comment Share on other sites More sharing options...
Farmer Posted June 19, 2020 Share Posted June 19, 2020 (edited) Lee FCD will contribute to it. I don’t use mine on cast or even plated bullets because of that and accuracy goes away too. Try just a reg taper crimp. Took a while to pin that one down on my 45 & 327 mag. If you have a tight bore it doesn’t seem to be as much as a problem. On the powder I’ve seen some that just have a tendency to lead more than others but it’s the last resort if everything else fits like it should.

George16 Posted June 19, 2020 Share Posted June 19, 2020 Like stated above, it’s the FCD that’s causing it. The BBI 147 Gr bullets are sized at .356” while the FCD is at .355. The FCD is swaging down your bullet to .355”. This damages the plating or coating and thereby leading your barrel. I only use the FCD on .355” diameter like the PD 124 Gr JHP and 115 FMJ. Other than that, I use a taper crimp die for everything else. Link to comment Share on other sites More sharing options...

DodgeNerd Posted June 19, 2020 Author Share Posted June 19, 2020 Best die/dies for coated .356? Link to comment Share on other sites More sharing options...
Farmer Posted June 19, 2020 Share Posted June 19, 2020 (edited) The RCBS TC will work fine, that’s what I use. Actually either one. As a side note the Redding Profile crimp die will size down lead/plated bullets also. Works great on jacketed though.

jpm2953 Posted June 20, 2020 Share Posted June 20, 2020 I was getting leading with .356 BBI’s when I used a FCD. It was sizing them down to .354” I went to the Dillon crimp die and the leading went away. the FCD is fine for plated and jacketed but not coated Link to comment Share on other sites More sharing options...
madmosche Posted June 22, 2020 Share Posted June 22, 2020 Do the newer Lee bullet seating dies also do a taper crimp? So when loading the coated bullets, that could give it enough of a crimp without using the Factory Crimp Die? I thought I read somewhere that the bullet seating die does some kind of crimp on its own. Link to comment Share on other sites More sharing options...
George16 Posted June 22, 2020 Share Posted June 22, 2020 There are different sets of 9mm dies that Lee sells. I bought one 9mm set with the FCD and another set with the Taper crimp die. Amazon sell 9mm Lee die sets with either an FCD or Taper crimp die. Link to comment Share on other sites More sharing options...

I don't mean which die comes in the set, but rather does the bullet seating die do some kind of crimp on its own so you don't need to use a separate die?

I see what you mean. It depends on what dies lee die set you buy. Lee has a combination seating and crimoing die on the three pack set they sell. However, it’s a lot more difficult to set it compared to a separate seating and crimp die. On my 650, the seating die is on station 4 while my FCD is on station five.

t-squared Posted June 23, 2020 Share Posted June 23, 2020 The carbide "sizing" ring in the FCD swaging cast or coated bullets down to jacketed sizes is a well known issue. Google "removing the carbide sizing ring from a Lee factory crimp die". There are plenty of different posts of people driving the ring out fairly easily...then you're left with a nice easily adjustable taper crimp die. Another option is to just buy a standard taper crimp die from Redding, RCBS, Hornady, etc. Link to comment Share on other sites More sharing options...
