It is commonly thought that setting a FL die to "Bump the Shoulder a few Thousands" will solve problems like incipient head separation that you experienced. However it only reduces case damage caused by excessive HS and not the excessive stretch at the neck, shoulder and base of a case. Neck Sizing solves this problem, except for the neck, but only if one does not overpressure the case so that it is sticky at the base. |
I got lucky today-case separation
Here's the hottest load I put through it during load development

I necked them down to my 20-223 EXTREME and found that the Winchester Brass trim length stayed the same at 1.750" while the IVI trim length came out at 1.765" or 0.015" longer. I know that both these brass hold the same amount of Powder and that a new Winchester brass , formed to 20-223, has only increased by about 0.006" on six firings moving a 40 V-Max at 3668+ so looks like it does not suffer from being FL sized each firing or being formed from once fired 223 brass. |
My Lee Colliet dies showed up today, and I'll reset my FL dies a little less than 1/4" above the press bump.
I'll keep screwing the FL die down a 1/2 turn down at a time till I get those tight brass too chamber easy... Then lock it in place with about 2 thousands free space. Awesome ideas on getting some extra life of of our brass. Don |
Lee collet die has worked flawlessly for me on 5 reloadings of 6.5-06 winchester brass. I havent had to bump the shoulders yet.
Perfect feeding and very low run out. Maybe it's because of the generous body taper or the fact I'm running these in one chamber exclusively. Factor in the cost and it's an outstanding solution. Sent from my SM-N920W8 using Tapatalk |
Yes, this is what I heard too Duramax.
I'm hoping my 30/06 case is forgiving in this reloading world. Another fellow from our shooting range has been using the Redding compitition die-set as he's had good luck with them. Neck, body dies are each of their own. I'm sure I'll be ok with the standard FL and Collit dies. Don |
Most people over work the cases because they don't adjust their dies to only bump the shoulder back enough to chamber easily. Regardless of what the instructions that came with the FL die recommends, setting them to bottom on the shellholder will usually bump the shoulder back more than required. I typically neck size, and then bump the shoulders back only enough to allow the cases to chamber easily, when it takes more effort than I like to chamber the cases.Purchasing once fired cases can also result in having to work the cases a lot more than desired f the chamber that they were fired in is on the larger size.

Thank you for sharing. I want to get into reloading one of these days.

Well, my lee neck die and new lapua brass came yesterday, so I loaded 20 rounds with same charge weight, bullet, coal etc
50 fps slower, so should be easy to adjust for that, poi a little low and right of previous. The question I have is this-anyone see any reason not to throw mag primers in, and would I expect to see much of a velocity difference? I won't test it until I fire form the other 80 pieces as they are already primed. "Shuuuuuuussssshhhhh. You can't post stuff like that, too many heads will explode." Hillbillyreefer |
