Reloading Question

Just learning, don't mind me.

Thanks I appreciate all the help. I will try all of these and hope fully get it to work if I dont run out of rounds first.

I wouldn't crimp either. But if you are going to crimp do it seperately. In other words back off your seating die. Seat the bullets. Then back off your bullet seating stem. Now adjust your seating die to crimp.

[Muddy Bud]

my suggestions:

dis-assemble the FL sizing die and the Seating die


polish inside of die using cordless drill and steel wool with FLITZ , polish die mirror fine


then adjust expander ball (on decapping stem) so it expands and sizes entire case neck

lube brass ..... personally I would NOT crimp the bullets

This makes total sense on why the bullet will get started and then stop.
Thanks Blake.

I didnt crimp my rounds that went into a bolt action. I will take a look at my load data and give you my measurements.

Do you chamfer your necks? Try a vld chamfer tool. 300 WSM has a very thick neck and you need to "break" the edge.

yep, need to chamfer inside and outside of case necks

then use a .30 caliber brush to clean inside of necks and remove powder residue

crimping is really only needed for rounds that go into tubular magazines. excessive lube can dent the case walls but rarely collapses the shoulder. if the case oal is long it could be butting up inside the die. you stated it was virgin brass, if so it should be sized then trimmed and de-burred using a vld or similar tool. i don't think you have a cartridge oal issue but maybe a trimmed to length problem.

If you have another 30 cal die from the same manufacturer you might try swapping the expander balls. Cases with high shoulder angles seem to be a little problematic. I was crimping the shoulder in 7-08 cases until I worked out a sizing technique.

If you want to crimp it use a separate crimp die made just for crimping cause it sounds like your seating die is adjusted too far down. If your brass is not all the same length and you adjusted the die on a short piece of brass and you try to crimp a long piece your going to collaspe the shoulder.

Got it figured out. Seating die was was bent causing the case to enter lop sided just enough to put excess pressure on shoulder. Swap dies and adjusted accordingly and the rounds seated perfectly. Thanks for all the other tips I will be using from now on.

the seat die was bent , or the seating stem that guides and seats the bullet ?


call the die manufacturer and they'll swap it out for free

I used to be in the accuracy work-up business and all the family of short mags and super short mags were problematic--but not as you describe--

Glad you found the problem--sort of like tuning a bow--work on one thing at a time until the problem is found.
