Every god damn one of the dummy rounds I've made load into the f'ing chamber, and then the f'ing bolt is stuck and I have to strain to pull back the charging handle to eject the round. Seriously what am I doing wrong here:
75gr Hornady Trim length 1.746 OAL 2.258 Compared to a BH Blue box 75gr Case length 1.757 OAL 2.248 |

Its a larue built rifle using a wylde chamber 1/8.
As far as I can tell the ogives are the same, the kinetic bullet puller seems to be worthless with bullets with a crimp so I can't get the tip out to do a good comparision. The only noticable difference between the 2 rounds is the BH has a cannelure and the Hornady doesn't. I've compared all the possible parts of the cases and they are within .001 with my reloads being the smaller of the two. I can't say how much this is pissing me off at the moment :/ *edit* Sigh so I found the first dummy round I made using a LC 06 once fire round vs the PPU's once fired I tried. The LC cycles perfectly, so I guess the PPU brass is crap :/ Ya I've got a case gauge on the way. |

First, measure the resized brass to make sure they are not over 1.760". Then you should set up the sizing die without the expander and screw the die down in 1/32 turn increments until the brass chambers. Since dies are threaded 14 TPI, each turn is about 71 thousandths. 1/32 turn is about 2.2 thousandths, hence the need. The headspace tolerance is about triple that so be careful.
Once the headspace is right, put the expander in and the die is set. If they don't chamber after putting the expander back in, the cases need to be lubed INSIDE the neck. Here, Lee resizing lube is prefered as it won't harm powder. Being a semi-solid, it will make a deposit on the top of the expander and this really helps maintaining uniform lubrication of the inside neck area. Just a tiny bit on every 5th case or so, once this lube has built up. |
| All my cases have been trimmed to 1.746, that includes the LC and the 7 PPU brass I tried. Bullets are all seated to the same depth......I guess I don't understand about lubing inside the neck more than I'm already doing and how that would affect the bullet getting stuck in the chamber. |

The case necks are sized a bit under the recommended 0.221" ID to account for brass with thin necks and harder necks which have more "springback". When the expander is pulled out, it will "pull" the shoulder out a bit, making for a tight fit. Lubing the inside of the neck will prevent most of this. Some reloaders get around this by using a bushing die which has a removable bushing so the neck is only sized enough for the ID to be 0.221-0.222". A range of bushing is needed to account for all the brass. Others use a body die for the rest of the case and size the neck with a Lee Collet die. If you are using a spray type lube, apply some to the inside with a Q-tip to test. You didn't mention brand of dies or lube. Most dies have the expander button pretty low on the stem, this makes the expander easier to pull out. But it also contributes to the problem as it causes the neck to be pulled off axis since very few cases have perfectly uniform necks. |

I'm using the hornady new dimension dies, and their one shot spray lube. Sigh and now I've got a case stuck in the damn die. I can't friggin win today :/ The best bet for One Shot is to lube the day before you size the cases. It has a lot of alcohol to enable it to be sprayed from a can. And it doesn't get enough into the necks unless they are sprayed when standing up. When I lube with Lee, I use it like hand lotion, then grab a handfull and roll them in my hands. The lube should not be easily visible on the cases, except to dull the shine. I can lube 500 a minute and it gets enough in the necks to prevent pull-out. Use wet or let dry, it is the same. |

I'm using the hornady one shot spray lube. Sigh and now I've got a case stuck in the damn die. Not using enough lube. One shot is notorious for this. Put your brass in a gallon zip lock spray heavily and shake well. Let dry. I switched to dillon lube from HOS and glad I did.

Thanks again for the help guys....I always seem to run into problems starting out on stuff like this :/ Your not the only one. I'll be posting my problem in a few minutes. One thing that helped me, when you start getting pissed walk away so you don't f*ck something up more  .

I never used the Stony Point gage, I use the Dillon case gage, if you size your brass so it falls in between the steps of the Dillon case gage and trim it so it's below the max case OAL your ammo will be good to go, unless you have an out of spec chamber. All my 223 reloads fit in my 5 Colt AR15's, just shot 300 rds of reloads this aftrernoon, no jams, no misfeeds, everyone went bang, rapid fire, slow fire, but mostly rapid fire.
