Sureshot BL-625 action video
JSR, Found some time to set up the pour. We had to heat the molds to around + 375° F before the tail started to fill nicely. Note the 9 volt battery and .177" (4.5mm) pellet in there for scale. Also a 2" UHMW blank for a pneumatic round we are planning. Oh, one of the first pellets that did not fill 100% was cut in half to show the skirt profile.

Beautiful, have any been fired yet? What does it weigh compared to a typical potato slug?

Action / damage video will be posted later when the new coaxial pnuematic gun is introduced.
Math says it should weigh .811 lbs, or about 368 grams.

Looking forward 
I take it the prototype Mike was telling me about worked well then?
I take it the prototype Mike was telling me about worked well then?The things you can do with a large machine shop. Yes, "It" does work well but there are a few technical issues. I do not want to steal his thunder. Another thing, I made the pellets to 1.5 sched 40, his test gun has an aluminum 2" sched 40 barrel. Oh well. When the VMC is open, there is a larger mold gonna be made...
Those "pellets" are amazing. With the weight of the 2" bore pellets nearing 1 lb and the new prototype easily running 200PSI (max current shop pressure) should be some serious energy. Replacement O-rings should be here soon!
I like that you included the UHMW slug.
USGF can you post the 20 minute ghetto dart from earlier?

I'm not sure about that really. The variance of slight changes and velocities plays a large part. Though however, when testing water rockets (same rocket, just different nosecone) the performance was greatly improved (max altitude) with a semi spherical leading edge. Though whatever works for you.jackssmirkingrevenge wrote:I beg to differ ;Pinonickname wrote:Unfortunately unless your going supersonic it will be rather inefficient but oh well.

1. Is for subsonic flight
2. Is for supersonic flight
3. Is for hypersonic flight
I bet those slugs would be awesome though..beautiful work on them. Destruction evidence shall be appreciated..

I wonder how many out there have experience with pneumatic intensifiers? We have endless 125 PSI shop air. So, with a 2.2 to 1 intensifier, we should easily see 250 PSI. Got most everything off Ebay. We will build one soon.
Hit the edge of a small c channel and left a endmill shaped crater. We will re-load and get a nice shot off on larger target.jackssmirkingrevenge wrote:haha!

Will these molds be for sale at some point? Or would I have to come to you as a client? If for sale, any idea on a general price range for say a mold for 1 1/2" SCH10? I would love trying different materials to make the pellets out of. I have a rifled barrel that would be wicked with wax pellets or a more durable yet soft material.USGF wrote:JSR, Found some time to set up the pour.
