Went back and read the whole thread makes more sense now... those look much better... still would try and get them cast as perfect as possible before swaging just for that last little bit of consistency... hope they shoot well... the similar BBT seem to... the slightly hollow base and fuller round nose are about the main difference that will/may move the Cg forwards just a touch...

it does look more involved than making the BBT 40g... and also with the pellet once you get the pins set right on the Noe mold...that is a touch fiddly... My stock Mrod does .75 at 50 with the 40g BBT when sized to .2495-.250 at about 750 fps...the 34g pellet did well also despite a bad transfer port oring...

Hope testing goes well..

a 45 grain Super Magnum pellet..

My casting skill is no where near any where like people on GTA. but i have bought a new lee bottom pour pot. man that thing pours like a giant ^*%$#@ hot molten lead. and the result is very very good!!! The old pot was pouring slow, maybe that's part of the problem i had.

Yah, I am ready to send out some batches to beta testers...I cannot wait to hear results back...the pellets are a bit rough but i think it will do just find acting as a bullet when driven above 950fps.

Thanks for the data on the BBT 40 grains. I think i should size down to .250 to test it out again

A new mould is made and ready. It was as per Dark Charismas requirement of a Heavy pellet in 22 cal. The heaviest one being 33.9-grain JSB. So I made a 36-grain pellet 0.421 long. 5.52 head. I think the airforce condor in .22 will like them. It also houses 3... 40-grain meplat .25 pellets (Images will be posted after I resize the Hd images to 100kb jpg format). The design for .217 slugs is ready but I am aiming for the .357 light and .357 Heavy in 70 and 88 grain. long enough to fit any mag and versatile enough to suit any gun high or low powered. Anyone Interested?

yep i have a .22 condor, it may like it...so the .217 slugs is how long at 70 grains?

Looks like the light .357 is 70 grains; not the .22...

The heavy 0.217" pellet is 36 gr....

The images are close Macro shots. Some pics of other popular pellets. (https://www.crosman-air-pistol-owners-forum.com/board/index.php/topic,637.0.html?PHPSESSID=pgoq75vbtfcd50oavr3tg390t5) suggested by the subscriber.
Edit: the pellets are 5.527mm and 6.36 mm in diameter all around, these pellets are not cleaned hence the parting looks pronounced. They are straight out of the mould. The cleaning operation is not done.

I like the looks of that Ken. I am interested to see the .357 light and heavy on your mold.

Going to send you some of Bobs design for .177 cal, 20 cal, 30 cal and 35 cal.

I really like the metplat pellet from Bobs design. going to test that out

The kit looks really good. Thanks for taking the time to make the video!

ken47 · « **Reply #131 on:** November 01, 2018, 03:41:50 AM »

Thanks, It was undergoing tests so I made a video of it. The mold will be commercially available and will be priced similar to some good casting molds. The swaging setup will cost sub $400 with the mold, press, and tools (tools from Amazon). Same as buying 2 brass casting molds. Molds will be available through an exclusive dealer network soon.

ken47 · « **Reply #132 on:** November 13, 2018, 11:01:34 AM »

.30 and .357 are getting ready. They weigh in at 60 grain in 30 and 102 grain in 357. Designs are made by simulating the pellet through a Lothar Walther barrel and checking it for friction areas around the pellet. Skirts are designed to deform in areas seen visibly engaged. A lot of engineering is involved in making the latest and most advanced moulds to date. Will be released soon for under $399 (shipping included) through dealers in Texas and other states.

wow looks really good I was try here in Chile create molds, but are very expensive the development, if u sell in .22 and .25 I and friends will buy definitely ur molds

tronickero · « **Reply #135 on:** November 28, 2018, 06:50:41 PM »

here other option , from russia with love

Thanks dude, The Russians make really good swaging dies, lot to learn from them. What about Chile? whats the issue with .22 or .25 pellets out there? are they expensive, Banned or arent avaliable?

Hi ken , here in Chile the airgun world are very basic, there are not engineer development in this field, I think I'm the only one. Here the pellets are expensive and more in larger caliber that is why i tried build molds to obtain high quality pellets with high BC, but is very dificult with clasic tools.
because these i search options to obtain good molds but at reasonable price. now exist the Russian and u

Im fan of high power airguns ,slugs with high CB and long range shoots. My dream is build a rifle as a "tale of three brod" and use cast/swaged pellets

Im very near to be engineer and have many desings of complete airguns based in rsterne builds and personal desings but here in Chile dont have aluminum tubes or plates, Cromoly tubes .....is very dificult buy these materials. barrels are imposible

greetings ken

Those Russian dies look beautiful on the outside and seem to make nice projectiles (based on the images).

A shortage of barrels is a problem. Perhaps someone might be motivated to make some in Chile (assuming it is legal). Alibaba have both unrifled chrome-moly "hydraulic tubing" for sale, and rifling buttons; from various suppliers.

For instance, these buttons are sold as "reamers": https://www.aliexpress.com/item/6-Flutes-Spiral-Reamer-5-81-9-35mm-Push-Rifling-Buttons-Double-Layer-Blade-Reamer-for/32921843699.html
Unrifled barrel blanks https://www.aliexpress.com/item/seamless-steel-pipe-OD-12-mm-long-50cm-tube-steel-Hydraulic-40cr-chromium-molybdenum-alloy/32872237301.html

This is a licenced gun manufacturer that develop unusual guns. Here he makes good barrels as simply as possible:

This second guy makes rifled barrels with crude tools, just to prove he can do it. He has a number of videos at this link: https://www.youtube.com/results?search_query=idahoan+rifling

Certainly, pulling a button through a rifle barrel is better than pushing it, due to the tendency for long driving rods to buckle under compression, and straighten under tension. Push buttons are more appropriate for short large caliber barrels. If operating at such force levels is a problem, there are many people on YT showing off their home made sinebar or spiral guide mandrel cut rifling machines.

For instance (one each of a series of these videos shown as a sample):

A long time ago I have in my workshop the idea of a machine to make barrels, I found a Chinese supplier of the necessary tools.

https://www.ebay.com/usr/riflingbutton?_trksid=p2047675.l2559

soon I will start its construction, but the difficult thing is to find the tubes of Cromoly with the correct internal diameter
