In the top photo the crimp is cleanly removed at the top, surface you can see. At the bottom of the same photo you can see the step from the crimp which will cause the primer hangup. I want a smooth even chamfer all the way around.Tested 20 cases with the Lyman and 20 cases with the Burstfire chucked in a drill. Held the case on the reamer with moderate pressure for a count of one second. Tested with the go gauge. 20 for 20 with the Burstfire passed, 14 of 20 reamed with the Lyman passed. Others are reporting their Lyman reamer works great so I’m guessing my sample of one maybe is out of spec. It really isn’t cutting much, even when pushing fairly hard. It just feels like the reamer is spinning free.
I will say, with a functional tool, reaming goes pretty fast (a lot faster than it did before with the Lyman, so unless my hands get tired, I can’t imagine anything other than an automatic case feeder into a swager, i.e. the Lee APP, being faster.
I’m going to prime 20 Burstfire reamed cases and see how that goes, and then move on to finish the 1,000 or so cases remaining.
First photo was reamed with the Burstfire, the second with the Lyman. Again, with my results and others’ reports, my Lyman reamer is not working the same as others.

That’s what I use, although I have coveted the Dillon Super SwageThe rcbs crimp remover is neither.... it only chamfers the top of the pocket and doesn't touch any of the primer walls. The reamer and swager do touch the primer pocket which make it possible to overdo.
Exactly, and I have so few I have needed to doI guess it is a matter of scale.
You have to swage hard to the hilt of the tool or it won't round the edges causing stoppages on a progressive, due to the edge not rounding enough and catching edges.
Looks like it's your lucky day I was just on the Lee website at the bottom of the page it says Swage and save. You buy the Challenger press or the App and get a free Ram Swage tool! Lee's dealers will likely have even a better price.I'm still in the process of figuring it out. I haven't had the need to do much with crimped pockets. The first time I did, I was using the Lyman reamer. I only did 20 or so cases, spun the reamer until it seemed to spin free of taking brass and still had issues seating primers. I wasn't using a gauge to check those, but I subsequently bought some gauges. After reaming some with the reamer chucked in a drill, I still had some issues. Recently started processing a bunch of my range pickup brass and knew I wanted to try something different than the Lyman reamer. I had an RCBS crimp remover in my inbox ready to buy, but after googling, saw a post on the forum referencing the Burstfire and checked out the Burstfire video. I know it's marketing and they aren't going to post their product failing, but they were comparing it to another reamer, and that showed the experience I was having. They also compared it to what appears to be the RCBS crimp remover, and I didn't want that experience, either.
Why reaming? Right now - because it's cheaper. Lee APP and Lee APP Primer Pocket Swage Kit = $182 VS Dillon Swager = $163 VS. Reamer chucked in a drill = $17
The "Automatic" part looks pretty enticing though. I think the Lee looks like the way to go for fast swaging if I decide to up my game.
I’ll try deburring after the Lyman. See if that makes a difference. Next step will be to try priming the brass reamed with the different reamers.
Lyman on the left; Burstfire on the right. They look similar, but are definitely working differently.
I'm also seeing a slight radius.

Separate question for those with more experience, if you use a primer pocket go/no-go gauge and it passes, how common is it to have issues when priming on a progressive press? I know it depends on the press, but in general. The pieces I've hand primed after using the burstfire seemed to prime just fine.
I have done multiple batches of mixed cases and not once had to adjust it............................for what it's worth..................you only swage the crimp (as you know) and adjustment isn't needed.....find that I have to fiddle with it due to case measurement differences.
I've had some tight GO's and some loose GO's. But I wouldnt toss either one because of that feeling. Im not gauging every single case either when im processing in bulk thats kind of cWazy.
I would like to understand the Dillon process. A case is inserted into the tool and held by a pin in the open end of the shell. Then the case is pressed onto the tool. If the metal size at the base of the case, from inside to outside varies, as is should, then you would have different depths of swaging. I gotta' be missing something here.I have done multiple batches of mixed cases and not once had to adjust it............................for what it's worth..................you only swage the crimp (as you know) and adjustment isn't needed.....
I've tried a couple different makes/models and after doing a few hundred LC I found the easiest for me is to just leave it lay on the ground and not pick it up in the first place. I have access to too much brass that has no crimped primers. Reaming primer pockets rates right up there is trimming.
