I've posted several questions on heavy 35 caliber rifle bullets lately, here's another. Can anyone identify the bullet on the left?

The one on the right I believe came from a lyman 358009 mold. I recieved a small box of these two bullet types from someone a number of years ago, and don't know what mold the second bullet is from. It weighs 301 grains with the gas check, unlubed. It doesn't appear to be sized, an measures about .362" on the driving bands. The nose section measures .350", with the small nose band at about .355"
For comparison, the lyman bullet weighs 275 grains, with the gas check, unlubed. I would guess both bullets are cast from the same alloy.
Here's another picture.

That driving band on the nose leads me to suspect it's an NEI design. You might want to check their catalog. Take a look at .358-300-GC #169 DD

Thanks, looks like you are right. That NEI mold does look very similar (the picture I saw doesn't show the nose driving band, but I see they offer it.)

Any thoughts on that nose band? It seems that it would prevent seating the bullets long enough in a lot of rifles. I need to resize mine before trying it out.

you could size the nose in a smaller die on alyman 450 then turn over and size the body.
i was going to say maybe an old h&g mold. but it could easily be nei know i have seen it recently
but not a poured bullet.

My understanding is that the nose band is supposed to engrave the rifling when you chamber a round. Being as small as it is it should not take that much effort to chamber and it should not pull the bullet from the case when you eject it unfired. That is the theory, I have not used one. NEI says that they will put that band on any bullet mould or leave it off if you don't want it.

The band is narrower than the bearing surface. It is supposed to make up for the fact nose bore riding designs are often actually a little under bore diameter in many barrels and that can lead to them tipping slightly in the bore, which affects accuracy. The band is supposed to force everything to center and line up by just kissing the rifling. I don't know if it works well or not? I don't have one of those molds. Bore riding cast bullet noses, at upper velocities, are often squashed shorter and fatter by their own inertial resistance to the accelerating force, and wind up touching the rifling anyway. Whether that band successfully helps them do that evenly or not, I also cannot say? It would be interesting to experiment with.

That particular bullet's mold line makes it appear the mold was jammed slightly open at the bottom when it was poured. Have you measured its diameter perpendicular to the mold line to see if it is wider than just either side of the mold line?
