    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Pretty recent. Bought it Black Friday, 2022. I assume that makes it Gen II? The rifle sets off factory ammo (American Eagle 55gr) 100%. It was about 40/40 on that ammo, and my ammo is probably 10-20% on the first trigger pull. So I don't *THINK* the action is at fault, but I have not...

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Take a look at the measurements above regarding primer height and pocket depth, as well as shoulder datum measurements. I hope you're right!!

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    I actually just set the shellplate before I loaded the last time. It was crazy how sensitive it was. Just a few degrees was the difference between feeling a wobble and the shellplate being completely locked up solid. But I think I had it as tight as I could get away with. I've considered one...

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    I tried to measure the firing pin protrusion, but it's hard without a real protrusion gauge. It's tough to tell if the calipers are completely and 100% straight. I was getting measurements from 0.052" to 0.057". What should that number be? What adjustment is there? Headspace wise, the cases...

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    So many good replies. I'll start with this one..... I measured 10pcs of new virgin brass from this lot, and they averaged a pocket depth of 0.1189". My CCI 450s measure an average thickness of 0.1195". So flush is about half-a-thousandth of crush. I measured 10 pieces of brass that I had...

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Yes, it makes me wish I brought calipers to the range and measured a few after the failure to see if they did seat deeper! I will manually try to seat some deeper and see how much they move.

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Thanks for this reply! This is what I did (and tried to explain in my original post, but I did so poorly), and I saw no difference in primer depth, but I will look into this again. Did you do this? Did it work? I went about 0.004” but was afraid to go too far without spare parts.

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Thanks for the reply. I will try to measure more installed primers, but they were all measuring almost exactly flush. The Dillon 550 really does not have a way to adjust depth. With that said, I have tried grinding a few thousandths off the bottom of the primer installation cup (several...

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    I've been attempting to load .223 precision ammo for a ARC Nucleus-based rifle on my Dillon 550, but I'm getting a ton of light strikes. Nearly every round does not fire the first time. I'm loading brand new virgin LC brass and CCI primers. The primers are as close to flush as I can measure...

    RCBS MatchMaster Dies?

    Because having a $10 spare part and changing it in 2 minutes without swapping out the die is a lot easier and more convenient than spending $50-$150 on another die, that then needs to be swapped in, readjusted, and may or may not act the same after taking significantly more time, then needing to...

    RCBS MatchMaster Dies?

    I love these Matchmaster seaters for Dillons, but last night, for the first time, I had a bullet not fully settle into the die. I didn’t notice it happened, and when I pulled the handle, the stem jammed into the side of the bullet, and it bent the stem. Probably my own fault for not watching the...

    American Rifle Company "Extended" Rails?

    Can anyone tell me for sure what the difference is between the "standard" ARC Scope rails and the "Extended" ARC Scope rails? I'm referring specifically to this page... https://americanrifle.odoo.com/shop/rail-m5-mausingfield-841 Pictures would be great if you have them. THANK YOU!

    6GT with 115 dtacs

    For anyone interested, David Tubb (SSS) has had 115 DTACs in stock on and off a lot lately. Apparently they're getting new lots every few weeks. I purchased another 2500 for my next barrel, and I can't wait to get them out to shoot them. And I've got nothing but good things to say about their...

    KRG New Products 2020 official...

    As I said, when I first got this chassis, I honestly looked at that and thought to myself "Well, I'll just clamp that down and never touch it". But the first time I took it to the range and was shooting prone, I laid down, and my bipod height was just a bit off. I could have shot it happily at...
