ok so i took 49 rounds and ran them through my sizing die (hornady 223) and i bumped back to 1.454 as my fired rounds were coming out 1.458-1.459
now majority came out dead on at 1.4540 or 1.4535 (yea measuring to 10 thousandths just for learning phase) I had 5 shells that did not meet these specs. 1 - 1.452 4 at 1.465-1.470 now...all will feed in my rifle and all pass the case gage. But especially the 4, i RERAN them through the die....same results. Thinking maybe die moved but doubting it, i grabbed another fired round calipered it to ensure it was 1.458 or higher, then resized, it was perfect so it's not the die setting. Is this normal some times and just happens? how will this effect me when i'm crimping and have roll set on my 1.454 mark? anything to check? |

Make sure to get some lube on the inside of the neck, or the expander ball may stretch the shoulder forward as it's being pulled out of the case. Some brands of cases behave differently than others as far as resizing. yea i tried the lube on the next...now i have two types the imperial powder and then the white stuff that comes in the forestor case brush kit. i must say i can't see much residue on the inside of the neck when i do it with or without the brush. I also learned to lube the entire case to get consistent. The other thing i did note was it was wcc cases, but....i found other wcc's in the mix i was sizing that came out just fine. strange. how often should you throw lube on the necks? as it slows down the process (i've been doing about every 5-6 rounds, sometimes i might even do 3-4 in a row then go to about 7 -8 more until i do another) |

I use a homemade case lube that is ~8 parts 99% iso-propyl alcohol and 1 part liquid lanolin in a spray bottle. I put the cases in a gallon ziplock bag, give them 4 - 6 squirts, then seal the bag and shake them up to cover them well, then open the bag for about 2 - 4 minutes for the alcohol to dissipate. You may have to fiddle with the lube recipe to get it so its not too thick or thin. I started with 12 parts alcohol, but it was too thin. I just added lanolin until it gets to the right consistency. Before sizing the first case, I put a small drop of pure liquid lanolin on my finger, rub it around the neck and shoulder, then roll the case mouth on my finger while scooping up the rest of the lanolin into the inside edge of the neck. I repeat this every 20 - 30 cases, or when I feel the press is getting harder to pull. Using this method, you will get very nicely consistently sized cases every time. I used to have the same problem you are experiencing, it all cleared up when I started using this method. YMMV. |

Available at wally world? (sorry not much into shopping for those things so i've no clue  )
Lol never mind the better half knew exactly what this was and where to get it. Said its common as water |

Good catch! My reloading is in the basement (53F degrees) so I put a nut in the spray bottle to help with mixing because it usually sits a week without use. |
| Not lubing the case neck enough has screwed me up before. My RCBS .308 die must have an expander that's way too big because it will stretch the hell out of a case in a second. I'm about to switch to Forster or Redding bushing dies so I can size the neck exactly how much I want. |

Lol never mind the better half knew exactly what this was and where to get it. Said its common as water Check out a product called "Fluid Film". We use it on the machines in our food production center because it is natural, non toxic and it just works. It is industrial quality refined lanolin without the "hippy added tax" Fluid Film Website |

Relative to my experience, that is very, very good...holding 1.4540 to 1.4535. I don't know how you do it. I do well to keep it within the 1.465 - 1.470 of your last four. You should see the shoulder tolerance show up again in the case trim length if you use a giraud or possom hollow trimmer that indexes off of the shoulder. |
