309JDJ trouble with brass *DELETED*

Post deleted by jimmylee

Okay, i'll bite, what sort of problems... are you sure it's the brass. I have two contender frames and they both lost their spring tension at nearly the same time, buncha "knowledgeable 'smiths told me it was a headspace problem, in spite of the fact that they quit firing in the middle of a hundred round lot of reloads. spent quite a bit of time screwing with this and that before replacing the hammer spring voilla!!no misfires-the strange thing was altho the 30-30 and 35 rem wouldn't function, the 7tcu had no difficulties whatsoever ...

What's your problem,Jimmylee?

After fire forming new brass I am only getting 1-2 reloades per cass. Brass for the 309 is made from 444 marlin brass. the case necks are cracking. Any help? thank you

Have you annealed the necks or have you thought about it?

I too have had brass splits for my 309JDJ.But now I think I have it under control.Start off with new cases,anneal them,only use Imperial sizing wax, watch your die settings.Kenny

Very odd. I have brass that has 8 firings on it and it hasn't split. As a matter of fact, I have a less than 10% loss during initial resizing. I went so far as to make sure I have extra brass just sized and waiting for failure and no problems yet. Maybe I'm just lucky.

Odd is right I'm pushing my 338-06JDJ and can get 4 to 5 reloads after fireforming.

Check your sizing die settings. could be a situation of excess headspace- by allowing too much headspace the brass is stretched too much at firing and then splits, this could be your problem. try re-firing the cases that didn't split, necksize only- when reloading- and compare the number of bad cases per hundred of the reloads with the original mortality rate. If it is significantly better, I would bet you had too much head space.-size your cases only enough that the gun closes and locks up. To neck size only, color the neck of the case with a magic marker, or "smoke" the case neck and adjust the sizing die down the neck only far enough to grasp the bullet, I go about thre quarters of the length of the neck- the sizing die will scrape off the ink/smoke as it progresses down the die.
