Please excuse my impertinence, but it would seem that the basic regulatory problem, that is the regulation of the use of black powder for purposes other than muzzleloading firearms, is independent of the source of ignition. I hope that I am incorrect in this read...

Use Pyrodex P. No more regulatory concern.

What's really neat about this product is that although it appears it is similar to AeroTech's Electronic Forward Closure, this product has been around longer, judging from the timeline laid out on the company's history page from their website. I wonder if AeroTech got their idea from this company, since the designer of the NoMatch displayed it at a BALLS launch two years ago?

Unless I am wrong, the canistor appears to be muzzle loaded.

Good going Oliver
, this looks to have alot of promise

Arnold,

While this device may be muzzleloaded, it is not an antique firearm and so it may not qualify for blackpowder use. Take a look at the lively discussion on the Regulatory strand on this subject. Don't get me wrong - it looks very cool, solves a number of problems, and I've got space in a couple of beauties to house it.




Are 2 grains of Pyrodex P enough, though? I get lower muzzle velocities on my Kentucky rifle with Pyrodex than I do with BP. But if you do use Pyrodex, though, make sure you clean it very, very well. Hogden recommends lots of hot water, and you might want to clean it several times after a use. I've stopped using Pyrodex in all but one muzzleloader, as BP cleans up much more easily.

Just sharing related experiences...

I would think a charge volume of 2.5 grams would be better suited for retail models, as it gives a little more fudge room for larger airframes, but then again even I have extended the BP charge well of an AeroTech 54mm forward closure by taping a short piece of 1/2 launch lug onto it.

As for using Pyrodex, I think you want to stick with Pyrodex P, which is the pistol powder, and is rated as FFFg equivalent. Pyrodex RS, for rifles and shotguns is only rated FFg and could produce lower velocities than FFFg or FFFFg black powder.

Also, I would like to see a "remote glow plug" option for this product, where you could mount the electronics with one orientation and stick the glowplug/ejection charge wherever you wanted.

You are right about the powder - the longrifle is .45, and gives vastly better performance on Pyroxdex P than on RS. This is about the cross-over caliber size recommended by Hogden, at least if you are using in in a rifle. I'm curious - what is the inner diameter of the ejection charge well on a 54mm forward closure? I wonder, since you said that you were using a 1/2" launch lug taped on, how this compares overall with the rifle.

BTW - I was in a different unit mode when I wrote the last reply, reading grams as grains. I had just ordered a number of bullets, all at 405 grains. My apologies.

The 2 grams that this new device takes is about 30 grains of powder, while the 2.5 grams you mentioned is about 38 grains. This is about the minimum charge I would put in a rifle, and my .36 Navy Colt takes about 24-27 grains of powder. One note - the equivalent charge between BP and Pyrodex is by volume, not weight. That is, the volume that 30 grains of BP occupies is the equivalent amount for Pyrodex, not 30 grains by mass. Pyrodex has a different density than BP.

A company called Track of the Wolf has a variety of powder spouts in different grain increments. A quick throw from a powder flask takes a lot of guesswork and mess out of loading.

I agree with you on the remote locating of the glow-plug. It would certainly simplify cleaning. Somehow, the thought of abundant hot water running across a circuit board does not thrill me much.

I am the developer of NoMatch and would like to take this opportunity to comment on some of the issues raised:




You are correct, that the use of black powder still falls under regulatory requirements, but at least the source of ignition (like some e-matches) does not.




The charge holder holds approximately 2 grams (not grains ) and can be upgraded to a larger size without any problems. I only charge a bit more for a custom size. When you order the unit, just specify the I.D. (1/4" minimum) and length of the charge holder you would like to order and I'll send you an invoice back with the cost for the upgrade.

Keep in mind when using Pyrodex, that containment of the Pyrodex is important for complete burn. Someone sent me a great website where they tested Pyrodex vs. black powder: pratthobbies.com/info_pages/pyrodex/pyrotest.htm

I personally like to use a piston system where the ejection charge is contained until positive separation is accomplished. This is one of the reasons I developed NoMatch, which makes it very easy to create a sealed piston system.




This is something I am looking into. Keep an eye on my web-page for any product updates.




As long as you briefly submerge the circuit board in alcohol after you cleaned the glow-plug with water you should be fine. The alcohol displaces the water and then evaporates. Be careful when you clean the glow-plug though. I wouldn't use a brush or even high pressure air near the heating element, since that might damage it.

Keep those suggestions and comments coming as I will try to incorporate them into future versions of this product.

What is this? The manufacturer reading comments and answering questions in near-real-time? What will the world think of next?

Why more manfacturers don't take advantage of the comments that readers leave and respond back to them is beyond me, but Oliver gets a big thumbs-up for reading our suggestions, considering them and then offering feedback to the community. Thanks, Oliver! Hopefully others will follow your example.

Aphyle

I agree 100%! Keep it up, Oliver!




Yup! That's what I said regarding the bullets and the powder charges! I have to order bullets by grains, as they don't sell them by grams. Ancient measures, you know!




That makes much more sense! Thanks.
