NOE's New Old Bullet

Just wondering what some of you more experienced target shooters think of this bullet. I notice NOE rounded the front edges of nose like Frank requested. Is this bullet designed for a rifle that has lots of throat erosion? How would you fit this bullet to chamber or vice versa?

looks pretty good for a match chamber ... but for an extended and oversized eroded throat it would not seem to ever touch anything but the rear groove diameter .... but that wouldn't be contacting much when chambered in an eroded production chamber ...   in fact, many production throats are way too long in the first place .... dang those jakkted bullets with not a care in the world ...

... but then there aren't a whole lot of rules in cast bullets  cool .

Don't know why you would want nose taper for a new chamber either.  Even worse for an eroeded chamber if the bore started out at .300" or larger.  if the bullets came out a bit larger and with the right eroded chamber you might get lucky and have a perfect fit, but probably not without some mold lapping.  However, the only thing worse in this type bullet is a nose too big to go into the bore requiring nose sizing -- at least for me.

At least with an undersized nose you can sometimes save the day with beagling.  Lapping the nose out to the diameter needed for a good fit is better but more work but only has to be done once -- until more erosion calls for more.  Lapping can be done to only the front of the nose by relieving the rear part of the lap. Having the part that fits the further forward the better.

"you might get lucky and have a perfect fit, but probably not without some mold lapping. " 

John

That is a very good way of describing it.

And like Ken says "looks pretty good for a match chamber"

Would bumping bullet work better than lapping or beagling mold?

Have you guys read a recent article in The Fouling Shot called "On The Road to Records"? He uses a bullet very similar to this bullet to break records...he listed ACC 311230E as bullet used, but sized to .312...so he probably bumped bullet larger. Article is a very good one, but leaves a lot out about type alloy used and throat description.

Good Morning all.  This may or may not end up working out for me but the reason I was interested in this bullet by NOE has nothing to do with eroded throats or chambers that are cut to match this bullet. My idea was (is until proven otherwise) Hey, I bet that bullet will feed great in my 300 Blackout AR.   We also have my daughters 300 BO that is a Handi rifle to try. The bullets I've had the most success with so far have been sized .311 on the bands and .301 on the nose. With my powder coating system that should bring the nearly 1/2" nose up to .301 to .303. I've been wrong a time or two before. We will see  I'll post up either way when I have a chance to give them a try.   Gp

I ordered the NOE aluminum 3 cavity version. NOE's molds seem to cast a little better than the Accurate versions for some reason? Better venting maybe? When casting I use only the front and rear cavity (not using center cavity) for better venting. Segregating both front and rear bullets when dropping from mold.

Bullet will be used in Contender chambered in 300 Whisper. Barrel is 1/10 twist with .309 diameter and .200 long free bore.

Am interested to hear how that works out. I have something similar, only in 6mm/223 with an 8" twist, going right now. The  Contender pistol barrel is supposed to show up on Monday. The intended 6 MM bullet looks much the same

This is the actual mold that the NOE represents.

The MX4-30-ARD has a parallel, .301 bore riding nose. NOE made it tapered, because many wanted it that way.

Behind that, it's tapered at 1 deg per side (that matches many leade's in match rifles), it doesn't end at .307 (.307 is a mid diameter) but, continues to .311.

The original MX4-30-ARD, probably holds more CBA records than any other bullet. At least 20 by Mel Harris.

I have the Eagan MX 330 ARD which when bumped becomes what is likely the bases for this later MX4-30-ARD version. My bumped bullet lacks the small upper GG.

Bumping the MX 330 ARD produces a tapered bullet that matches the lead angle.  Basically, making fixed ammo to address an 'no breach seating' demand.

 For what it is worth, I have an interest in Eagan molds. I think the thread topic relates to this mold as well.

 

This is the MX 330 ARD mold and the bullet out of it after it has been bumped to what I think might be the MX-4-30-ARD before Eagan made a cherry for it.  That is a guess.  Edit - also my bumped bullet lacks the larger flat on the nose.

This thread got my attention because the above drawings look to be this bumped bullet but with the added upper GG. Any info someone can add would be interesting.

Your MX3-30 ARD was designed for Ardito's throat of 1991. That throat has a 1/2 deg (per side) leade and this bullet matches that.

The bullet, as cast, has a good BC. Bumping it, as you do, even though it is more pointed, reduces the BC.

If you do not have the 1/2 deg throat, I think it would shoot better, as cast in that throat.

With it's 1.14 length, it's a good bullet for a 13 or 14 twist.

I guess the trick is fitting the bullet to throat and zero loaded neck clearance against neck area of chamber. After firing, bullet can be seated without resizing case, new loaded round is chambered with slight resistance against neck and tapered throat (custom chamber reamer).

Here is a picture of die I made to squeeze the bullet to desired shape. Each bullet is squeezed exact amount during cam over of Rock Chucker press. You can use ether the expanding or neck crimp Lee die body to hold inserts for shaping or squeezing. The Mini lathe makes it possible for me to make these.

You can also press the tapered bullet into tapered die insert before sqeezing fatter and more round.

I received my mold and inspected it using magnifying loop. Some of the vent lines were clogged in band area of cavity caused by burrs leftover after cutting. I removed these burrs using sharp lead pencil. Next i scrubbed cavities using electric tooth brush and Arm and Hammer toothpaste with baking soda. I then sanded top of mould using 220 grit paper and flat surface. The rougher surface holds more lube to prevent sprue plate gaulding during opening by hand (downward pressure against mold). Aluminum molds will gauld more easily than brass or steel.

I really like NOE's mold lube. Apply thin film using QTip before and during casting. Too much lube will contaminate  leaving ugly bases and bullets.

I received my mould yesterday and cleaned it up and temperature cycled it as per NOE's instructions. Within about 20 casts it was dropping nice bullets. This is one feature I appreciate about the NOE aluminum moulds in that the ones I've purchased don't take a lot of breaking in. As for mould lube, I like the tip I was given by Gary. I now use dielectric silicone grease under the sprue plate as it does not migrate into the cavities and lasts a LONG time. A little bit goes a long way so don't get carried away.  On the pins I use 2-cycle oil.  First rounds sent down range today out of my 300 Blackout AR. Sadly, I was a bit timid with my load as it was just a WAG. 200gr 299s have been cycling just fine with 12.5gr. IMR 4227 but this bullet weighing an average of 217.5 won't cycle the bolt with 10.5gr. Wind was whipping today so no attempt was made to shoot a group. No problem hitting clays at about 60yrds. though fired single shot.  I'll try some as cast as soon. The ones sent today were altered and powder coated. the nose was sized to a strait .301 and the bands were sized to.311 Looks like it's worth some exploring as a 300 blackout bullet. Gp

2 years ago I wrote 3 articles on the 300 Blackout. These articles were published in TFS. The point of this is that after shooting a 300 Blackout in matches for 2 years, I settled on 3 powders : 4227, H4198 and AA1680. I shot the 311299 about half of the time. Go slowly but you may well find best accuracy north of 12.5 gr.

This new NOE bullet does not fit my Thompson very well...bumping or sqeezing is needed to make fit. I need to make nose punch to match nose (35 degree included or 17.5 per side angle) so I can squeeze from .299 to larger .301

For now I will be using my custom Accurate mold 31-210M instead. This bullet has been bumped from .299 to a larger .301 for perfect strait bore riding fit. The long free bore diameter of pound cast is .3095. Bullet Bands are about .3093 

I have never shot this bullet in any gun, but I believe it will shoot very good?

 Frank,

Yesterday you wrote, "The bullet, as cast, has a good BC. Bumping it, as you do, even though it is more pointed, reduces the BC."

In my simple mind I always thought  longer, pointier (technical term) bullets had better BCs. Why am I wrong.
