I'm not sure, but I suspect that anything much smaller than .470" could need a special extractor.

Yes, I used a cull staple to hold the cutoff open so I could photograph the region of interest. I have been working with Damnesia on those, but to date do not have a repeatable process for one critical phase of the operation.

Here is an update on the alternate method of handling short cartridges. I like it better because it has no snap-in parts. It uses a split collar spacer on the carrier to prevent forward movement of the cartridges due to recoil. Parts are hand made and crude, but it works. Cartridge guide took a LOT of work, but ended up having a lot in common with a 243 guide. Magazine loads very smoothly, rounds feed into barrel as hoped. I cant fire it because I don't have a 41 mag barrel.

Sam,Looks good!!! I may end up doing something similar with the 414.I had a Barrel bored and chambered by JES hoping it would clean up bad spot in the chamber area but it didnt!! So i went and rechambered it in 410 and that cleaned it up. I have to send out another barrel to JES before i can continue on my project. Don

I may change my mind about not firing it, as I can take a junk barrel and hog it out such that the 410 bullet will make it through. The primary purpose of firing it would be to demonstrate that the recoil barricade works as believed. I personally have no interest in a 99 chambered in 41 mag, but I never asked the question, "Why bother?" I bother because I learn. The things I learn can be transferred to other situations, other calibers, etc where it means a lot to me or someone else.

gnoahhh suggested some time ago that I write one of my technical notes on the cartridge handling characteristics of the 99. I have not done that yet because I don't think I know enough yet. Although I have done around 40 customs, I still get surprised. This experience has brought me closer to being willing to start writing.

I have removed the 41 hardware from the testbed rifle, but it is bagged and tagged so once I bore a barrel I could in a few minutes assemble a functioning rifle and go shoot it for closure.

Is there a short cartridge that does click your trigger? Experiment with that


What you have done is not nearly as important as how you have done it!!!

In all honest frankness... I'm about blown away. The only thing between me and such project(s)... As Time, Talent, Tools & Tenacity. Especially the latter. I do congratulate you all mechanical engineers here as artisans to accomplishing such goals.
A factual nod of admiration as perhaps to patience and sense of commitment leading the way!
Good Luck!

Thanks for the kind words. I discovered some interest in the 41, so will proceed with it, and take it up to the point of firing in an unrifled barrel. If that all works as hoped, I'll have a real barrel made and see if I can hit something. Whatever I do, I will at suitable times, provide updates to this group.

Wow! Gotta echo what others are saying. Respect and admiration to this group of creative, talented pioneers in the development of some fascinating pieces. I have really enjoyed reading, looking, and learning. Thanks to Sam and so many others of you (especially from this thread).
