I would love to see this . It should fit just about any airgun barrel and be good with stock power . There is a shortened mold being tested and the groups are very promising.
I talked to Al about this, and he did up the drawing, so I believe it is planned at some point…. Certainly adding your name to this thread can’t help but speed things along…. here is the drawing of the HP version…. It is planned to make RG2 ad RG4 moulds, so that you can cast Flat Nose, Hollow Point, or Cup Point, just by changing the pins (supplied)….
While this started out as an airgun slug, there is no reason that if there is enough interest, Al could not make them in 0.225″ diameter as well…. but note, this bullet is too short to have a GC stub, it will be PB only…. He even said he could do a 0.250″ version, which would be about 40 gr. (HP ~38 gr.)…. I’m on board for an RG4 as drawn above…. Incidently, this bullet would fit in a .22 cal MRod magazine….
