      Any interest in a multi-cavity version of this one? It’s a tapered bullet that weighs 195 grains. Because of the taper it is a great choice for magazine fed guns. It’s been a good performer in my 300 Blackout AR which has a fairly short throat. You can seat it out to where the mouth just barely covers the lube groove and it will still fit in the magazine and feed perfectly.

          Bumping this back up. I assume Al received the samples and was so blown away by their awesomeness that he is grinding a cherry now :)

            I’m interested in one.

              Any chance of a .314″ version of this design?

                Couple of thoughts here.  John Ardito, who I understand designed that bullet, was far less concerned with BC than with accuracy.  My Lyman version was terribly undersized and out of round, I re-aligned the blocks and knurled the cavity faces to make it round….and it casts .300″ exactly on the nose from ogive break back about 3/8″.  The main portion of the nose is exactly parallel, the drawing presented here is far better as it indicates a shallow taper transitioning to a steeper one, which is a well-proven design.  What will be an issue for many people is the .300″ dimension being so far out toward the tip of the nose.  Many rifles will not accept a bullet that is even 1/2 thousandth larger than bore diameter without pushing it back into the case.  Without exception, I have found NOE moulds to cast at least that much and up to .002″ larger than the drawing indicated with common WW alloy and no additional tin.  If the mould is made and casts .301″ or larger on the nose (adding any tin makes the issue worse) this bullet will be useless in all but the most worn and largest-bore rifles. If the rifle will accept the bullet at .301″ or larger due to wear, it will likely leave most of the middle of the bullet’s nose unsupported due to the common throat wear pattern of .30-caliber rifles.

                What I would like to see is the nose dimension at the trailing edge of the ogive reduced to .299″.  This would ensure adequate ease of chambering with most rifles and alloys that will be used, and also increase the more oblique nose angle slightly, which could also be an advantage to both BC and accuracy.  Reducing the nose size would practically be a requirement for autoloading rifles.  I have an M1A, three .308’s with various chambers, and two .300 BLK rifles and NONE of them will accept anything larger than .300″ past the end of the throat taper.

                If I were to keep wishing, I would also like to see a crimp groove located so the rear of the “band” in front of the crimp groove is about .850″ back from the tip of the nose for .300 BLK, but then that might call for a new mould number.

                  In total agreement with a .299 or even .298 nose with a taper.
                  But a crimp groove would make it a totally “new number”
                  Would be happy to put something together on a new thread.

                  Two sizes shouldn’t be a problem (.310 and .314)

                    Al,

                    What did the samples I sent measure at the nose? That’s what I would hope for in a NOE design. For my wants, a smaller nose is better than a larger one. I already have plenty of molds with fat noses, and they all require seating too deep in 300 blackout, 30-06 and 308 autoloaders.

                        Well, I like the nose numbers. The bands could be a little bit fatter. Maybe that’s why it chambers so easily :)

                          The .298″ or .299″ nose with a taper would work fine for me as well.

                          Swede:  Thanks for agreeing to .310″ and .314″  Can I assume that a corresponding fatter nose will accompany the .314″ diameter version?
