and yes both of mine needed leade work to send the 40g BBT mainly because of the rear band catching and causing the short round to load cockeyed... for every pellet but the Benji domed the stock lack of a leade was not a prob... but the Benji domed sprayed...now that they both have a low angle tapered leade the Benji domed do almost as good as the JSB 25.4...as good as the Cudas and better than the H&N 20g at 50 yards...

If just shooting pellets I do not think all that low of an angle is needed for the leade like it is for some slugs...but yep just hard edged rifling cuts into the Benji domed skirts because of them being harder/stiffer skirted...

Hmm, both my G.M. gen II .25 are ~.2497/.252 ...are you sure yours is G.M. ; how many lands and grooves...

I think your results are more typical. Perhaps I was not making good measurements in this thread:

I haven't bothered with sending mine back yet. I figured I would let him catch up on orders first.

He doesn't really do email, been there and tried that. Eventually he did return my message. You'll really need to call him.

Ed, I'm going to try and get out this weekend and make a few more. Going to be really careful about ejecting them this time. The skirts on mine are uniform thickness which suggests that they are being cast correctly and getting crushed when they come out of the mold. They are normally the correct size across the split line, and short 90 degrees which again makes me think there could be operator error involved and I need to look at my process more carefully. I'm thinking I need to slow way down, eject them while still on the pins and then carefully remove them from the pins and measure. I think I checked the pins to be round, but now I can't remember, that could be another issue but not very likely.

I'm not sure at this time if the hunters are or aren't shooting accurately. My ldc is clipping.

Any body get their hunter mold replaced by Al?

Greg_E · « **Reply #208 on:** October 10, 2021, 12:56:48 AM »

I haven't had a chance to try my original again to make certain it isn't my fault.

Spacebus · « **Reply #209 on:** October 10, 2021, 09:58:36 AM »

I see I was a few months late getting into casting and missed out on the .25 pellet molds!

EdinGa · « **Reply #210 on:** October 10, 2021, 11:02:57 AM »

I haven't sent mine back to NOE yet. Life has been crazy.

I sent my mold back in July and just called Al yesterday. He seems committed to give us new molds but he has to make some first. If you see them on his website call him, I am pretty sure he will ship you one.

One reason I called Al is I got a new 25 caliber gun, a P35, and I shot a few of the cast pellets from my last run that I still had through it. The groups are about half the size of the groups I got shooting my Avenger. With it's favorite pellets (FX 25.4) the Avenger shoots smaller groups than the P35. But my Avenger is a lot pickier about pellets than my P35. My Avenger hates H&N FTT, for instance, and that is the best pellet I've tried so far in my P35. When my Avenger doesn't like a pellet, it didn't like the cast ones, it scatters them into 1.5 to 2 inch groups at 25 yards. It puts FX into 1/4 inch groups at that distance regularly. When the P35 doesn't particularly like a pellet, it will still put it into a group under an inch. It puts FTTs into groups under 1/2 and inch usually. At least one group with the cast were that size and all were under an inch.

Al admitted the mold was casting pellets undersize but said in his test of it they were only under by about half a thousandths. I measured more than that which he thinks is either alloy or technique. I don't know. All thinks I may not have had the mold hot enough.

I plan to try and remember to check the website to see if he lists them and then call him to make sure mine is on the way.

If you know anybody with a 25 caliber you might try giving them a few pellets from your mold to test. If they work better for them they might be interested in your mold.

EdinGa · « **Reply #212 on:** October 28, 2021, 10:10:13 AM »

I've run mine hot, cold and everywhere in between. I've tried different alloys and pure lead. It's dropping small no matter what I do. I'm getting close to being in the 1k club and I own quite a few other molds that I've never had this issue with over thousands of casts.

I have no doubt he will make it right, and I will send mine back eventually. I just haven't had the time or energy to do it yet.

JimD · « **Reply #213 on:** October 29, 2021, 01:36:30 PM »

Eddie,

You are certainly a lot more experienced than I am. I have difficulty ruling out a possible contribution from my limited casting experience. But I tried different temperatures and also pre-heated the mold. But what I was suggesting in my previous post is that I think part of it may be that my Avenger doesn't like this pellet. If it was a little bigger I'm hoping that helps but it may not. I have not slugged the barrels but I think my Avenger's bore is bigger than my P35. I've noticed that the JSBs the Avenger really likes drag some in the P35s magazine while the ones that just drop into the P35 magazine are the ones the Avenger doesn't like. So I think size is also a contributor.

I shot another 5 groups with my cast pellets today with the P35 and it again grouped them OK. Not great but I would call the accuracy usable. Hopefully it will be even better with my new mold (whenever I get it).

I think my P35 tolerates pellets a little on the small size better than my Avenger.

Jim

I don't know the bore size of the.25 Avenger but I know the.22 barrel is on the small side. You really need to slug your barrels to know what is going on.

Wayne52 · « **Reply #215 on:** October 30, 2021, 05:44:24 PM »

Rob you're exactly right about that, my Liberty shoots .215 diameter excellemt whereas my Challenger 22 shoots the .218 diameter excellent just like the slugs drop from the NOE 218-25-RF.

Spacebus · « **Reply #216 on:** October 30, 2021, 06:09:05 PM »

For what it's worth the pins in my .457 mold don't always sit flush with the bottom of the mold. I first noticed it when casting flat nose as some had a slight recess and others were fully flat. That would definitely affect the skirt on the .250 hunter molds. I might pass on slug molds that use pins in the future because of this inconsistency.

Greg_E · « **Reply #217 on:** October 30, 2021, 06:16:46 PM »

On the other NOE mold I have in .357, I found that procedure was important! You need to figure out which way to turn it when closing. Some may be upside down, some may be right side up. Sounds like your is right side up.

I got my replacement mold from NOE today. It arrived with the mail a few minutes ago so it will probably be tomorrow before I fire up the melting furnace and hot plate pre-heater and see if I can measure a difference (I have a few of the pellets from the mold I sent back) and, more importantly, if they shoot different. When I bought the mold my only 25 caliber was my Avenger but I recently added a second, a P35. The P35 shot the prior molds pellets a lot better than the Avenger did. It will be interesting to see how both guns do with the new molds pellets.

JimD · « **Reply #219 on:** November 19, 2021, 03:15:15 PM »

I cast 50-60 pellets using the lightest (longest) pin today. I don't really see any difference from the pellets I have from my old mold and my guns don't seem to see a difference either. Groups from my Avenger are still all over 1 inch. I got a couple groups about 1/2 inch with my P35 but that was with the pellets from the old mold. Groups with the new mold were generally around 3/4 inch but some were over 1 inch. All my groups were at 100 feet which is about 30 meters. I don't think the two smaller groups were because the new mold is better than the old, probably just my casting technique or shooting. I am pretty sure my AV just does not like this pellet.

I will probably mess around with it some more in the P35 but I don't see hope for the Avenger with this pellet. Fortunately I still have some FX 25.4 grain it really likes. I haven't tried pellets that are cast with the shorter pins in the P35 nor have I tried going up or down on mold temperature. I tried all those things with the Avenger and it did not help. But it might in the P35. If it does not, I will put my casting stuff away and just shoot purchased pellets - at least as long as I can find them. Actually, the P35 seems to like slugs at least as well as pellets. I have some Nielsen on the way to try.

My measurement tools are not terribly precise, a digital dial caliper, but the skirts on the pellets from the new mold are still significantly smaller in diameter than the H&N FTT my P35 likes. But I am not sure that is the issue. Earlier I measured the cast versus the FX pellets my Avenger likes and thought the smaller diameter was the issue. But the Avenger hates the FTT pellets the P35 likes. The FTT are if anything larger than the FX pellets. My working hypothesis is that my guns do not like these pellets very much. That's not fundimentally different from the P35 liking FTT more than FX or JSB while the Avenger really likes the JSB/FX and hates the FTT. Neither like Benjamin pellets much.

I think it is a quality mold but unfortunately the pellets it makes my guns do not shoot very well.
