Tumbling loaded ammo question

[Tuna]

[QUOTE=milboltnut;489137]No it does not, that is purely your opinion. Only on larger cases such as 460, 480, 500 or long cases

It would seem you do not read the manufactures instructions as the ones I have all said "To lightly lubricate cases" and yes I do agree with you about cleaning them before sizing BUT many do not do this step and think because it's carbide that it won't
matter.

sorry tuna.. thought you said carbide, not carbine.

I have since learned that a standard flaring-type expander die is not the way to go with cast bullets, if you want best accuracy. A Lyman M two-step expander allows the projectile to align best with the case, with no distortion. Now, there's no way to do this on a 550, but it too will eliminate any slop from bullet (not case prep) lube on the outside of the case. My cast loads routinely exceed my jacked loads for accuracy - and stuff smeared outside the cases just show that the lubed projectile isn't entering the case concentrically. Problem solved!
