Occasionally crushing cases in my new Loadmaster

Postby CurlyShuffle » Mon Aug 28, 2017 12:59 am

Hello,

Somewhat recently I got my first LoadMaster (40 S&W). I've been able to load a little over 200 rounds so far (all 180 gr Hornady XTP). Once I've tinkered everything, it seems to run pretty well, with one occasional exception. I've crushed 15 cases. I would guess the obvious solution to this would be to crank down the flare die a bit more, but I don't want to run into an issue where the indexer doesn't go through a full stroke. Should I change out the bullet seating die to the Hornady seating die (I have their 3 die set) to minimize the issue? Or is there another solution I should try?

Get rid of the Lee flaring die and replace it with a Lyman M die. I use them for 9mm, .40S&W and .45acp. They are much more forgiving of minor differences in case length than the flaring die and I have not crushed a single case out of multiple thousands that I have reloaded.

What do you use as a powder drop if are using the Lyman M die for flaring?

Websterz, When I did some additional research on the Lyman M dies, I came across a YouTube video from FortuneCookie45LC regarding Lyman dies. He mentioned that there is a separate attachment for the M dies that give it the same powder through ability as the Lee die. You would then use the Lyman powder measure. Is that the setup you use in conjunction with your Lyman M dies?

I'm running a Lee Auto Drum for my powder measure and I have it backed out of the turret just enough that it adds no additional flare to the cases. No additional components needed.

Websterz how are your dies setup ? Is it size , prime , Lyman m die , Lee auto drum , then seat and crimp in one step ?

I deprime in a single step prior to wet tumbling, then I hand prime with an RCBS Universal Hand Priming Tool.
When reloading I leave station 1 empty. #2 is the Lyman M die, #3 is the powder drop, #4 is bullet seating and #5 is the Lee Factory Crimp Die.
Leaving #1 open prevents crushing case rims if the case pusher doesn't get the case fully on to the shell plate. As the plate rotates to #2 any short stroked cases are nudged into place by the case retainer at station 2.

Curley, I reckon you have it all straightened out by now, but is it at the bullet seating station were the crushing occurs? Are you using a bullet feeder or setting by hand? If set by hand, does the bullet sit just a little into the case and stands up plumb to the case? If so there is not much else that should be needed. I load 40 short'n weak with cast lead and coated cast lead bullets with ease and can not recall ever crushing a case at the seating die. I have crushed one or few at the size deprime when the case feed rod is beginning to bend a bit. When I use an M die I place it at station 2 to act as my primer alignment assist (not that such is really needed). The M die is chiefly a diameter thing, although it will bell.. Then I set my powder through just a tad deeper to get the flare I desire. I seat next without crimp and crimp at final station. With jacketed bullets you should not need an M die.
