The drawing shows.256 for the skirts

The drawing on the NOE website says .257. I haven't found one yet that is that big. Every other NOE mold I own drops fat. Just my luck this one is undersize.

What are you using to measure the skirt?

Using my micrometers I only got.248-.250. I'm going to try and cast some up tomorrow. Mines a aluminum mold so maybe heating it up higher will give me the right size skirt.

I'm using a digital caliper. If I rotate the skirt it varies from .249 to .256 on different pellets.

I guess the small skirt size is the reason I can't use these pellets in my Sumatra's mag.

This is about average at 30 yards.

Hmmm, hope it works better in my Kral. I still haven't done more than open the package and glance at it.

When I'm weighing my pellets when I see one that's a little light I'll eyeball the skirt to make sure they look good with good sharp edges. I've measured them before and they'll always be very close to what the mold spec's call for. I've always had excellent results doing it this way. I think I only had 2 rejects from about a 200 count run during my last casting session of my 250-27-RF mold with the longest pin.

I'm using pure lead that I got from GT Bullets. It came from a split pig ingot too. I ran my pot hotter last night, and if anything my pellets were smaller in diameter. They look great though.

I weighed the pellets I cast today and they were coming in at 26.5- 26.9. The skirts were still in the.250-.252 range.

I weighed everything I cast last night and picked out everything 27 grains and above. The skirts are still undersize. Most ran .253-.254 I didn't bother measuring anything that was under 27 grains.

I need to push a pellet part way through my Kral, and another all the way through. I have a feeling this might not have been a good purchase for me.

I'll have to get mine cleaned up and cast a few, I have a replacement Lyman 9mm Devastator hollow point arriving Tuesday that I'll want to test ASAP. Otherwise I have a pile of stuff waiting for test and tune that I finished powder coating last night. Need to make a post on that subject. Melted down more rounds while chasing better flow-out. Toaster oven are VERY nonlinear, and the Lyman digital thermometer is incredibly slow during heating. Still finding powders that I like too.

I'm not happy with mine at all. I wanted the 34 grain, but settled for this one. Should have known better. I've got quite a few NOE molds and I've never had one undersize before.

Well, I have the .22 magnums mold and they drop undersize.
Back on topic, would this be a case were lapping would be a remedy?

I'm not sure how you would lap a mold like this.

Speaking strictly for my mold, I am planning on casting a pellet in each cavity and attach a thin rod to the top, use valve lapping/grinding compound and give each cavity a couple of swirls. Clean the mold, cast, measure pellets and repeat if needed. Either valve compound or JB which would probably be better.

How are you going to attach the rod? That might be the only hope for this mold.

I haven't "noodled" that part yet but give ne time, I'll make sure to pop back and let you know. Taking care of my mom is taking up all my time.

Take rod, flatten end with hammer, hold in place and cast around it with the sprue plate swung out of the way? Won't be perfectly centered, but might work. Need a ladle to poor the lead.

That's the general idea I am playing around with. What I was thinking was to cast with the sprue plate out of the way and attach the rod to the lead blob on top. The pour hole seems too small to allow the rod in place and be able to pour/cast the pellet.

Eddie

Have you shot and recovered an undamaged pellet and measured the diameters for the head and skirt,
with the same lead you are casting with?

I don't under stand this PC of pellets/slugs/bullets, can you build up the thickness enough to get a good fitting, so you can measure the dimensions etc.

IMHO,
I suspect that you also have a slightly larger bore diameter along with the smaller side of skirt diameters etc
which may be leading up to your accuracy problems.
