Alpha Dropper Powder Funnel

$39.00

 

Reloader's rejoice... The Alpha Dropper Powder Funnel is here and it’s compatible with All Dillon powder measures.  This funnel was designed from scratch and takes care of any and all issues associated with the sub par funnels that were previously available.  This is compatitlbe with bullet feeding dies.

The benefits:

- Material used is overkill... 30 Hrc internally hardness with a 67 Hrc hard low friction surface finish.  

-No more sticky scratched up worn out funnels.

-The machine polished punch tip is tapered to greatly reduce the sticky release chunk on the upstroke.

-That same taper is perfectly sized to capture your bullet tightly.  All bullet types tested 100%.  Your bullet tipping over on index problem is now reduced.

-Ported and polished powder path for maximum flow and it’s Larger than anything available.

-With the Alpha Dropper you will experience a more consistent powder flow rate as well as tight bullet placement. It’s the last powder funnel that you will ever need to purchase.

SETUP NOTES, PLEASE READ

** Powder measure die adjustment IS needed....

** DO NOT DRIVE THE FUNNEL TO FULL DEPTH... that will over bell the case and kill bullet neck tension.  The chart above is a starting point.

** Measure your previous brass for your favorite bell diameter.. setup the Alpha Dropper to match OR LESS, but do understand that unless you run new brass, you have lots of variables.  The Alpha Dropper will typically run perfectly with way LESS bell.. remember it's a taper now... 

** Some have reported of their Alpha Dropper top funnel locking onto the Dillon powder measure out tube.. don't panic.  We have great reports from commercial reloaders of a more consistent charge.. It rides with the measure and doesn't allow for loose powder to get caught in the gap.

** 9mm/38sc Typical Brass Bell measured Outer Diameter: 0.385-0.390.  Also refer to chart above.

** 40s&w/10mm Typical Brass Bell measured Outer Diameter: 0.435.  Also refer to chart above.

** Keep your funnel clean, we recommend using XXXX Steel Wool.

** We also recommend using Brass Juice case lube for your reloading.

Alpha Dropper

I have been reloading for over 30 years and a couple of years ago I found the Alpha Dropper. This is the most ingenious invention for a Progressive Press since they have came out. Here are a few reasons why this is the best addition. The material used is not Carbon Steel like all the others, it is made out of a Stainless Steel which will not rust. Another is the taper, what this allows you to do is come out the case very easy and being the taper is so gradual it reduces the over working of the brass mouth like the others do with the Bell. Being it is a slight taper it will not work harden the case mouth which can cause cracking. At $40.00 this is a must for reloaders.

Flawless!

Huge upgrade over my Dillon 9mm and 45 funnels. Case stick force is probably reduced by 90%+ for my wet tumbled brass! Bullets sit perfectly inside the cases with very minimal flair - it's hard to even see the flair without measuring. The surface polish and nitride finish is fantastic - you can see the attention to detail, especially where it counts on the tip. If I had a 10mm/40cal to load for I'd order the SSI funnel instantly. I couldn't be happier with this purchase! I wish SSI made funnels for more calibers... I'd buy funnels in 38/357 (9mm may work, but haven't tested), .224 (with improved internal hi-flow geometry!) .257, .264, and .308!
