Thanks for this, I will give it a try. Sent from my iPhone using Tapatalk

This is all mixed head stamp once fired brass. Mostly Winchester, Federal, and Speer. I just started doing a very slight ream to knock the edge off. 300 rounds loaded in the last hour with no visible damage. Sent from my iPhone using Tapatalk

Thanks a bunch for all your help. None of my problems were the fault of the bullet. See my post. I guess I'm getting a lot of once-fired brass with edges too sharp on the inside. After reaming, I am able to load quickly without damage. Since the ID of the Dillon seating die is 0.430, it will swage the 0.438 flare down to that anyway so I set the flare to 0.429 which is still plenty as long as there is no sharp edge on the inside of the case mouth. I'll be giving you a call to order another 2200 of these tomorrow! Sent from my iPad using Tapatalk

Try reaming the inside of the case mouth. If you are buying once-fired brass from the same place I am, this may solve your problem...it did mine. Sent from my iPad using Tapatalk

Yes, this is the new coating.... at least on the 200 gr. RN's Sent from my iPad using Tapatalk

I measured the ID of the Dillon seating die and found it was 0.430 because I noticed that the flare was less coming out of the seating die...basically it was about 0.430 ... makes perfect sense! So I set the powder die funnel to give me a 0.429 flare. This did improve things but still was getting a damaged bullet about every 5 (2 out of 10). Decided to try RaylanGivens suggestion and reamed the inside of several cases and dropped them in the case feeder. This solved the problem completely as I was able to load about 100 rounds without an issue. It will take a little extra time for case prep but still not as bad as rifle cases. I sure Thank everyone for all the suggestions and help in this thread! I also Thank Donnie at Bayou Bullets for all of his efforts to help. He took the extra effort to load a bunch of these 200 gr. RN's trying to duplicate the problem I was having. It looks like I must be buying the wrong once-fired brass and no one else is! It is sure a comfort to know that there is help readily available in this sport though. Thanks everyone! Sent from my iPad using Tapatalk

Ok, set the flare to give 0.438 at the rim. Placed bullet carefully to be level, pulled the handle, and got the first photo. Pulled the bullet to show the second photo. Close examination of the inside of the case mouth shows smooth, nothing to scrape the bullet. Sent from my iPhone using Tapatalk

The crimp is not the issue. The issue is the coating and lead that is being pushed up around the case mouth (inside the bell) during bullet seating.The load is Bayou 200 gr. RN @1.182 OAL on top of 3.9 gr. of VV N320 - Avg Chrono (20 rnds) is 840 GPS The bullet is being damaged during the station 4 seating. I can see lead and coating inside the case bell. I believe the bullet is tumbling due to this damage. I have found that if I take several seconds to make sure the bullet is exactly level I can get a bullet seated without damage. At this point, I may as well break out the single station press for only this bullet. No such problems when I load lead, plated, FMJ, 9mm, 45 ACP, or 223 on the Dillon 650.

Actually it's quite possible. You could be belling to an extent that the sizing die is squeezing the case down as it goes in the Redding seating die. Redding has their roots in benchrest and they just seem to keep their stuff on the tight side of things. I had to send in a Profile Crimp die to be enlarged because it was swaging the brass down with a cast bullet which usually run .001 bigger than a jacketed. Their CS was great and they had me send the die, 6 bullets, and 6 cases and they would make it work. They did. When discussing it with them all the measurements showed that it should work and they admitted that they really are intended for jacketed, but should work with a .001" over cast bullet. I had them take out .001" and it works fantastic now.If you feel any resistance at all as a sized case enters the seating die that is probably what's going on, it should slide in with no resistance or contact at all. Good stuff. Unfortunately I have tried the Dillon seating die instead to the Redding. The Dillon was about 0.420 inside dimension so it does not affect the bell at all. It does a better job but still I get lead pushing up inside the bell of the un-crimped case about every 5 or 6 rounds. I pull the bullet and see that the coating and some lead have been scraped upwards from the bullet base on a small area on only one side of the bullet. The XL650 is a 5 station progressive so there is always some pressure each stroke from the sizing die in station 1. But I am able to feel what I think is increased pressure whenever a bullet is being damaged in station 4. I do not use a bullet feeder, just by hand trying to set the bullet level in the case bell the best I can. It seems like the only answer is that the case internal diameter is ending up too small for the Bayou 200 gr. RN bullet in some instances, but not all. Sent from my iPad using Tapatalk

I have reduced the amount of case bell to the point where the bevel on the base of the bullet rests very slightly within the bell. This is pretty much the setting I started with for the Bayou 200 gr. RN's. I also measured the internal dimension of the seating die and found the Redding to be slightly less than the Dillon seating die so I have put the Dillon seating die on station 4. The combination of these actions has caused a reduction in the frequency that I detect lead showing at the case mouth within the bell, but it has not completely alleviated it. The instructions for both the Dillon and the Redding seating die's say that these dies do not provide any crimp and that a crimp should be done on the next station which is exactly my set up. What is a little confusing is that the powder measure funnel actually expands the case mouth internal dimension to about 0.399 below the bell and the bullet itself is only 0.400. Sure seems like this would be sufficient and not too tight to damage the bullet coating or push lead up but that is sure what is happening. The bullets do vary in diameter very slightly but only about 0.001. Sent from my iPad using Tapatalk

LOL, I actually do tumble completed cartridges to get the case lube off but that I only use on rifle rounds. I think I have seen what you are talking about. But in this case I get nice round holes shooting Montana Gold 180's at the same set up. Exposing lead is not going to work well in the rifling unless the whole lead bullet surface is evenly in contact. I can tell that these rounds I am loading are not removing the coating evenly and neither shaving the lead evenly. I'll pull a few this evening after I check to make sure the seating die is not crimping the case in station 4. Station 5 is the intended crimp die. Thanks for the ideas!

I will check to see if the seating die is crimping. If it is, it is not to the point of bringing the case mouth edge in contact with the bullet but it might be removing some of the bell. The intended crimp is at the next station and that is set to only remove the bell. Sent from my iPhone using Tapatalk

What dies are you using? I am using all Dillon dies but the seating die is Redding competition. I am wondering if the sizing die is making the neck of the case too small. The neck is about 0.39 after sizing but the belling funnel does widen the neck to 0.40. With a 0.020 bell, the bullet base drops into the case about 0.12 which is plenty. But even so, lead appears when the bullet seats. Sent from my iPhone using Tapatalk

I am loading these 40 S&W on a Dillon 650 using the standard Dillon powder drop and case bell. I am seeing lead and coating being scraped off the bullet during seating (1.182 coal). I have experimented with several belling diameters but this is not the cause. Material is often seen after bullet seating regardless of the amount of belling on the case mouth. The Bayou 200gr RN is right at 0.40 and seems to be unable to be seated in a sized and belled case without material being remove. These loads are tumbling so I need to solve this issue.
