Excellent product! I did have to smooth out the shoot to get the primers to fall smoothly but it has worked flawlessly since. This is a tremendous time saver. If you’re not looking to spend the $$ on an automatic primer tube filler but still hate manually picking up primers then this is your solution. Highly recommend!

Didn't do well with Remington 1 1/2 small pistol primers but did really well with CCI 350 small magnum pistol primers. A real time saver when bundled with the Combo: PRIMAFILL, 2x 5 pack DAA Primer Pickup Tubes and Primer Rack!

So my Frankford Arsenal VibraPrime finally died and after loading 7 tubes manually I had to get a primer loader ASAP - a good excuse to get this product. Unexpectedly the WSP primers proved somewhat of a challenge having to manually tap it occasionally to get the primer to fall in. But otherwise seems to better than VibraPrime until after finishing my 600-round loading session. Found 21 rounds with the primers flipped!! These would've flipped during the primer pick-up tube filling. Some may say 21/600 isn't much. However after loading 30-40K with the VibraPrime without a single flipped primer I think 21/600 is 21 too much. Looking at the design of the primer outlet chute, it's slightly deeper compared to the VibraPrime which makes the WSP primers flow better but this makes it prone to flip. The coarser and lower frequency vibration of the Primafill also makes the primers "jump" more making it more prone to flip compared to the VibraPrime which has a finer higher frequency vibration.
But the one good thing I like about this is the primer pickup tube locking mechanism. That is a real plus compared to the VibraPrime.
Saying all that, we know WSP primers are slightly irregular in thickness due to the anvil sometimes not seated in the cup properly. This causes the primer to get stuck in the primer outlet track/chute in the VibraPrime having to manually remove it. This is not an issue with the DAA Primafill.
I will try this for a few more 600-800 round loading sessions. If I keep getting flipped primers then it's time to shell out for another VibraPrime.

dear Boon,

Primers really cannot flip over while falling down the exit hole. The size of the hole is too tight. They can only end up upside-down in the tube if they approached the hole that way.
I am sure that when you flipped them on the flip tray you visually inspected that they were all correctly oriented. What could possibly happen, in some cases, is that the lid is slightly warped/bulging upwards, which allows too much of a gap between the tray and the lid. In such a case, a primer may flip over again while being fed towards the hole.
If this is the case in your unit, the simple solution is just to apply more pressure down on the lid as you operate the device in your hand. That will prevent the gap from being too large under the lid and solve complete your flipped primer issue. If this bothers you much, contact us for a replacement lid.

I have used the Hornady 45 vibrating primer filler and the Vibrafill from Dillon but both were a disappointment.

I used the Double Alpha unit to load some large rifle primers and was delighted with how well this device works. I think the vibrating action is more powerful than either of the other two units which seemed to aid the filling action. I'd say this one is a home run and I highly recommend it.

So far I like it. It can be a little finicky when flipping primers due to pattern of the ridges, but overall it works well. Those last few primers are usually going to have to be flipped by hand, otherwise you end up flipping some in the wrong directions. As to filling the tubes, get the angle right and they flow right in without issue. So far I've used it with CCI, Federal and Fiocchi. CCI and Federal are a breeze, but because of the way they're packaged, Fiocchis are a little more of a pain, but once the tray is ready they fill the tubes just fine. It seems well built and overall I'm very happy with the purchase. I think it's a hard to beat time saver for the money.

I bought one and could not get ANT (Rem, Win, Fed, or CCI) to drop. Spent hours trying to get it to work. Sent it back at my expense and received a refund within two days. I hoped this would really work.
