9mm loose bullet

[Xoneloa]

Just got into reloading and starting off with 9mm loaded correct length and all the only issue if anything is the bullet feels loose its crimped and it doesn't move in or out of the case it just spins inside the case like a .22 lr is this acceptable or is there a way to make it like a factory loaded round? Thanks

It happens, particularly with some plated or jacketed bullets. Try loading it in a magazine, then chamber it via the slide. If it doesn't set back and get pushed in, you're GTG (just don't do it too many times with the same round).

Most of the time, neck tension is sufficient to hold the bullet in the case and too much crimp can cause the case below the crimp to expand and loose tension. Then the only thing holding the bullet in the case is the crimp.

It chambers without an issue just worried about the bullet twisting thank you!

Assuming you have calipers, measure the diameter of the bullet itself to confirm it's 0.355.

Back your seating die off a bit and seat a bullet to the same OAL. Does the bullet spin? If not, you're crimping to the point where you're bellowing the case where the bullet sits. Ideally you shouldn't need much of a crimp to hold the bullet.

Hmm. This doesn't seem right to me. I will admit, I've only been loading for about 1.5 years but in that time, I've loaded about 30k 9mm rounds. I've never had this issue loading various bullet types.

It would seem to me that you don't have enough neck tension and you're over crimping. It may be crimped enough to keep the bullet in the case but with no neck tension it spins. Neck tension is what holds the bullet in the case in a pistol round, not crimp.

Is this happening with all the cartridges you've made or just one/few?

If it's just one/few, pull the offending bullets and measure with a caliper as someone else suggested. I would guess these are undersized. If it's all of them, then it could be your die setup. Are these new or used cases? Did you resize them properly? What type of crimp die are you using?

As mentioned previously, try pushing the bullet deeper into the case on one of these that are spinning. Easiest way is to hold the round between your fingers and push the bullet into your bench top then take a measurement to see if it seated deeper.

These rounds should fire safely from your barrel. However, accuracy will probably suffer. You may even get tumbling of the bullet which will be evident by a keyhole shaped hole in your target.

The crimp die is only used to remove the bell that you formed on the case mouth for autos, over-crimping squeezes the bullet. The case springs back and the bullet is now undersized, that is your problem, been there done that when I first started hand loading. As was suggested, back off the die until you just remove the bell, case gage or drop test the round in the barrel, if it goes you are good.

Have you looked at Lee undersized sizing die. One of my reloading friends ran into the same issue using used brass.

Yup - this is the likely answer.

change your brand of bullets to a jacketed bullet and your problem should be resolved. It is very uncommon to have a die that is oversized from the manufacturer. I have been known to polish my expander die a time or two to narrow the initial plug. This should not be necessary with correct diameter bullets.

Normally the effects of that will show up as not chambering easily, not with a loose bullet. Press stretch will cause the base end of the case to be unsides (or undersized) due to the die not coming down far enough. The mouth is sized as normal.

Backing the seating die off worked no movement and solid thanks everyone!

I love happy endings!
