Borrowing an idea from the Group Buy on the 65 gr. bullet, I have had a look at the possibility of making a second, shorter, lighter version of the 78 gr. BBT available.... I have yet to discuss this with Al, but I see no reason it could not be easily done without another set of tooling.... In addition to making the 78 gr. version as drawn, by simply not plunging the tooling as far into the mould block, it should be possible to make a version with a shorter boattail having a larger base diameter.... ie the exact same shape but missing the back 1/16" of the bullet....

Not only would the bullet be lighter, about 72 gr. instead of 78 gr.... placing it half way between the 65 gr. and 78 gr. BBTs.... but the shorter, larger diameter boattail would mean the bullet would be easier to stabilize.... There is no reason that the shorter version should not stabilize in a 14" twist, which is the standard for the commonly used 25-20 barrels.... I would definitely be interested in both versions, but some with interest in an airgun bullet in this weight range may have been shying away from this design because of the 11" twist recommended.... If you are interested in getting a shorter boattail version, please post in the discussion thread at NOE.... http://noebulletmolds.com/smf/index.php ... 096.0.html

If we get enough interest, I'll likely be able to convince Al to run both lengths/weights for us.... as the 78 gr. version is already in Group Buy....

As usual Bob your at the leading edge of cast slug tech. And congrats on have your trigger set design being used in Tom's new Evolv gun's. Any idea when the 357 mould's will be ready?

Nope, none of the .357s have proceeded to Group Buy yet.... we need more guys to post in the discussion thread for the weight they are interested in....
