Self Reliant Airgunning - Pellet Production

[milegajo 595]

This evening I've undertaken some long overdue ballistic coefficient calculations on my "Tomahawk" Homemade pellets.

 

The results were interesting, though not exactly too encouraging. The pellets are a tight fit down the 97kt barrel as well as the Th208. However the .22's are very loose in my chums HW100! bizarre.

 

Thankfully accuracy was very good but range is limited with the 97 showing severe drop off over just 15 yards. Here are the chairgun results.

 

 

 

As you can see by the graphs, the drop off is most pronounced in the .177 through the HW97kt, I may perform further trials using the tx200 tomorrow out of curiosity. I've reported the findings to the chap who makes them to help him refine and modify his future products.

 

It doesn't help that both guns are still rather new. The 97 may benefit from a strip down, the TH208 from a tuning kit. My conclusion is therefore that these pellets at present are best suited to FAC rated air rifles. Though should the proverbial poop hit the fan I'd still be happy to sling these at some pigeons! Boy they would pack a punch i'm sure.

Keep us updated, this is interesting!

An interesting project , and one that a mate and me tried a while back, but sadly with LEM which was pish,

The hassle is that it can cost as much in heat production as it costs for pellets sometimes. lol

 

Dad on with it though, it makes a great thread and something different

I'm using charcoal that costs £4 odd a kilo to buy luckily its pretty efficient.

 

I'm a bit concerned/am hopeful I miscalculated somewhere. I'll see what they're like through my new HW95 at some point.

Milegajo, I am an ex plumber, and noticed that you are using old lead flashing in the production of your Tomahawk pellets . May I suggest putting about a table spoon of tallow into your moulten lead , this will bring all the impurities to the top which you can skim of with your ladle. Also in the past I have melted lead in an old steel pan on the top of an electic oven as well as a gas oven. Cheers and good luck Sherlock.

Thanks for that tip, will give it a go when i do the next batch.

Hiya Miles, are you going to the meet up tomorow? I hope to go but google says estimated fuel usage £19.26! I hope thats for there and back. I have a few bits I dont use some of them brand new so it might be worth my while depends as well if the weather is kind. Cheers.

Hi Tron,

 

Yup, hope to be there from 09:30-17/18:00.

 

Hope to see you.

 

Many thanks.
