HELP on keeping bulet straight

[bjay]

Ive been having hard time seating bullet straight.. i can FL case with bushing dies and neck will be straight acording to my concitricity, but when time to seating bullet WOA! run outs are terible to .007 i even tried seating bullet halfway raise ramp then twist round to 180 degree then complete seating bullet.sometimes works maybe 40% at a time..i bought couple seater for my 7 saumand 6creed and still no luck.. its even harder to seat bullet straight with HYBRIDS.im using classic and LnL hornady reloader.i even removed rubber ring on hornady bushing making dies free float still not geting result thst i need.. am i missing something here is my neck to tight? I use sinclair expander die..any tips?
(Pls excuse my grammar and english)

when you say your case is concentric..... it has to include the the I.D. of the mouth of the case.. where the bullet is inserted.i.e neck turning req`d.... otherwise you are at the mercy of brass quality.An inline seater or forestor competition seater sure helps.

Why are you using an expander die? Are you using it after the case comes out of the bushing die? Have you altered your seating plug, with sandpaper to make it vld style, dumb to say the least?
If you can, try running a bullet on the concentricity gauge just to rule out it's not in the bullet, reaching here.

Try seating a couple without expanding, then measure.

If you have to use the expander try this...loosen the expander lock nut and run the case into the die until the expander is in the actual case mouth. Then tighten the expander lock nut. Try it again with some different cases and see if that don't help. If that don't improve things consider a L.E. Wilson straight line seater blank and have it cut with the same chambering reamer you did the barrel with, {if that is even possible.} I can get most of mine to within .001"-.oo15" with that setup, but as long as they are within .003" that will do it. It is proven that there is not much to be gained by having them better than .003" and definitely not worth worrying about. Hornady makes a tool that is supposed to correct non-concentric seated bullets after the fact but I have not had the privilege of trying one yet. Good luck.

I forgot to mentioned i also tried the process of not using expander at all and try take advantage of using bushing die..but still the concistency is not there... altho i would have those days that 80% of rounds a reloaded stay inside .0002.5 run outs.. im just curious if missing or lack on something..

Bjay, as you know I use custom Hornady bushing dies with 270 bushing and no expander, Lee shellholder, Lee Classic press and I started with Hornady seater but now I use the Forster Ultra Micrometer 6xc seater, either seater produces no more than .003" runout, usually it's next to nothing. Im not doing anything special and it's going pretty good, hope you can figure out whats going on, maybe a different set of eyes might help, have one of your buddies come over or make a video of what your process is.

Maybe just the way im seting up things.... i can produce straight sized brass but when time to seat bullet.... problem starts lol

I think the problem is your brass........... wall thickness variance..... can only be corrected by neck turning

But, the Hornady brass is very consistent in the neck thickness, 14.5-14.7 from one side to the other does not merit neck turning.

Also check the inside of your bullet seating die for dirt that may have built up inside the cup that holds the front of the bullet. If the piece that holds your bullet is crooked, or the stem that you screw up and down to adjust the height is crooked, the bullet nose gets held at an angle while you are trying to seat it.

I have bent a couple of the rods that adjust length of the cup that holds the bullet's placement, and everything comes out crooked. Another issue I often find is dirt inside the shell holder that gives me crooked brass from the start. Check the concentricity of the cases after sizing. You have to check the outside of the case, the inside and outside of the case neck for concentricity first though. If case and the inside and outside of the case neck are concentric with each other, then the problem would sure seem to be in your seating die.
