I have been reading this thread from the beginning and someone mentioned a Tap Test. Excuse my ignorance but what is a tap test? I have not heard that phrase before.
It holds it very nicely. Ever tried a lever action with bullets that are not crimped ? There's no neck tension in the world going to stop setback.Once Again...Crimp DOES NOT HOLD THE BULLET ... Neck Tension does. TC is just to remove the flaring done to seat the bullet.

Lever guns are normally rimed cases. Which is different on what we are discussing here. But yes, I have loaded for them and simi auto rifles (magazine feed). I do put a roll crimp if the bullet is designed for it. But most of the bullets I have loaded did not have the cannalure and I did not put a crimp on them. Did not have a problem and these were loaded near max, 308W. But it's std practice to roll crimp rimmed cases.It holds it very nicely. Ever tried a lever action with bullets that are not crimped ?

I only load +P and +P+ and if I do not crimp with a roll or FCD there will be bullet setback.

I use an RCBS hand chamfer tool, so isSo after some thought, I chamfered the inside of my .40 brass mouths enough to allow a jacketed bullet to seat straight, and without shaving
a trial & error thing till you get a good feel for needed amount of chamfer?chamfer enough to allow bullet to seat straight
If it was handgun ammo, it may be taper crimped not roll crimped, you will not see a taper crimp by eye.Are you sure? The couple times Ive looked at crimps on factory rds, a few boxes appeared to have no crimp at all..and I wondered if they ever go without crimping. These had no trace of a crimp that my inexperienced eyes could see.. Maybe they're more perfectly executed and harder to see...?
So you do apply a crimp.@ jell-dog
In my experience, it can vary depending on what bullet you're seating. With the old Hornady 147 grain 9mm boattails all that was required was to remove any burrs or high spots that could scratch off flecks of the bullet jacket, seating the boattail did the rest.
On the other hand, unlike some others here, I've never been able to get away with not belling my cases when loading cast bullets. I've come close with some loads, but I'd still occasionally get that big smear of lead down the outside of a case that would hold up production and leave me with a 49 round box of ammo.
I HATE loading partial boxes of ammo!
Without complicating the thread discussion further, so far this is what I have:9mm: is crImping always necessary
I wouldn't call that successfully.I loaded successfully for a long time with a 2 to 3 per cent rejection rate.
