    the maker have tested some 48grn air bullets which were 18mm long. 48gr bullets started to tumble at 35m. soon discovered that their weight distribution was 40% front and 60% tail. With the same design in 40grn which were 15mm long there was no tumbling and accuracy was 1/2″ at 35m. These both had a 3/4 F shape nose (similar to that of a spitzer). With a 3/4 E shape nose (same as a 9mm) they can cut the length by about 2mm and maintain the same weight. they think that 40grn is pretty much the max weight they will be looking at. Speed will also increase spin and better the stablization so you will need a very powerful air rifle to shoot those 40grn bullets. they will have 30grn available for those with standard 25-35fpe FAC rifles. with modified BAM.20 they were shooting the 40grn at an ave of 920fps @ 75fpe. also claimed when the final mods done it should be shooting at 85fpe in .20cal!

    Pics of new air bullets now with the skirt as previously mentioned… The nose might change from F to E depending on tests.

    Boondock!! Glad that you got my message.

    Those bullets look brutal although a little on the long side. I think however, that if they can get 1/2″ at 35m then that is a very good performance. Sure, they will never be as accurate as a JSB or Kodiak, but they certainly have their place for purely hunting and not punching paper.

    Those are all .20, right? I think that if they can get that kind of accuracy with a 40g .20 then they should be able to get better at a slightly heavier weight with .22 and I don’t know how heavy they would end up in .25!

    Those are impressive. Do you get to hunt much with those in South Africa?

    They look like real hammers on prey!

    TeflonTron… those .20 bullets currently under testing… should be ready next month according to the maker… after then they will finish .177 / .22 / .25… surely .22 and .25 will be more heavy… should be interesting..

    Adam… hehe… i don’t really think i need those bullets at this stage.. coz the biggest thing i will hunt will be Egyptian goose… weighted 6kgs… EJ should do fine with it.. but some people might wanna shoot something bigger or hit as hard as .22lr subsonic… then they might need those bullets..

    That they do! I’m interested in them because everything that I know tells me that they shouldn’t be stable, but if they can shoot sub 0.5″ at 35 Yards, then they seem to work okay. I think that a lot of testing would be in order.
