Dear Ralph,
I hope and believe we will receive useful information from CH4D.
Thank You very much.

Your lading data is very interesting. Not so light bullet, good amount of relatively fast powder and excellent velocity, and all that for lead bullet. It is very good. For that velocity the lead have not to be soft. You need hard casts alloy. The expacivity of hard cast bullet will be low. May be it would be interesting for you to make experiments with 300 grain 0.429 handgun (shotgun) jacketed SP bullet.

Many years ago, when we (I and my father) bought this drilling, we also began our empirical experiments with lead bullets, but results were not satisfactory. My construction of bullet mould was not so good. I decided to use jacketed bullets. It was impossible to find any reloading components. The brass were made by lathe. So it’s capacity was limited due to cylindrical interior shape. I used 3.75 grams (approx 58 grein) of powder and it was the maximum possible capacity. I used powder from rifle cartridges (Russian 7.62x54R). It was BT powder. It is more or less similar to Vihtavuory N140 or Reloader 15. My semi-jacketed bullets was about 21 g. (325 grain). I don’t know the velocity. I was also limited in pressure due to soft berdan primers (for smoothbore cartridges).

Now due to some political and economical changes much new became possible. A lot of different information on the web also may to help. At last I began to understand what the gun I have and what the cartridge I need.

Now I decide to renew cartridge system to more modern using not handmade, but real reloading equipment, brass, bullets. Also primers and powder are possible to buy now. I began experiments with brass fireforming. I will use 30R Blaser (RWS) brass. (Bertram and it’s Grundig is too far from me).

About pictures. For great regret this forum does not allow to attach picture direct to the post in forum. You may only attach a link (or so called hot-link) with address where You picture are keeping (so called image-hosting). There are a lot image-hosting sites on the web. Partially they are freeware, but partially not.

Is very popular in our forum.
I use
http://www.largeimagehost.com/
It is not the best and it’s interface is not the friendliest, but hot-links are free and without limitation on size.

You simply have to find and chose the appropriate web-hosting-site, to registry account and upload Your images to Your album at the chosen web-site. Web-site will generate special codes (simple html-link or BB-code for hot-link). You will copy and past the string of codes (also so called URL-string) from Your album at the hosting web-site into Your post. If it will be a hot-link the image will be visible in the post (as my). If it will be a simple link it will be necessary to click on the link to open the image.

If You want to send images not to the forum, but direct to me You may use my e-mail:

Here You can see one example else (at our forum in 2006 year). This old drilling cannot be for 444 Marlin. But it is possible to put 444 Marlin brass in chamber. If it is possible to use handgun 429 bulllets for shooting (as written) so that drilling can not be for 11.15x65R (429-Diameter is too big for 10.75 and too small for 11.15). I suppose it is drilling for our cartridge.

Sincerely Yours
Oleg
