 Got my mold a few days ago, had a chance to cast a few today. Mold needs a few cycles of casting to break in, but so far its working well.  Small dipping method seems best pouring method, bottom pour is too much volume for the small cavities.  Hoping for better weather so I can get a good casting session in soon.

  This pic was a cast 59gr .30 pellet next to a  AA 10.3gr .177
I haven't had a good chance to cast other than this 1 test session. Weather hasn't been right.  I am a noob when it comes to casting, lemme see how well they turn out after a few runs. I dunno about selling any, but I will think about it?
 This batch was a tad oversize, they were a hard push to feed on my setup. I think the mold plates need a few more cycles of heating to match up perfectly.  I did weigh 10 random pellets, they were all within a half grain spread !!
 I will be concentrating on my .300 Mrod in the next few weeks, I'll get some cast asap.

I cast about 50 keepers of the 66 grain yesterday. I picked up a hot plate last week. It made a huge difference. You have got to keep the mold hot for the skirts to fill.

We tried pre- heating on a wood stove, didnt help much.......
 I hope to cast a little tomorrow, maybe use a heatgun?
 Ive ordered a hotplate and infared thermo from Amazon.  In the long run casting .30 pellets will be cheaper than JSB 😅

It worked well for me. I still need to pick up a thermometer and some lead of known alloy. But, it is definitely nice not worrying about how much each shot is costing me!

If anyone with any of these molds gets to feelin FRISKY .... id be happy to help make your molds pay for themselves and buy up some of the pellets you make so i can try running them through my Ataman. Supposedly ( yes i know i need a chrony) the Atman spits those JSB 44's out at 984 so im looking to try these heavier pellets and see what results i get . Though i will say that within the 50 to 60 yards i have tested the JSB at the Atman seems VERY accurate. BUT im ready to try running the HEAVIER pellet through it.

Ive been lucky with my lead supply. A few friends are saving pellets from their indoor traps. My casting mentor then melts it all up, then mixes to 2.5% tin
 Helps it flow into the mold,  fills the skirts perfectly.  We may test some 5% too, but wanna break in the mold before measuring for dropped size with 2.5%
 Gonna cast some tonite, nice wearher here today in Ohio.
 Id love to have someone help pay for my mold, but I'm not a buisness, this is my hobby.  I don't even have enough cast for meself 😄

I received my mold and broke it in I then cast up a 100 or so using to different pins I got 59.5-60gr and 63-63.7gr shot them through my Warp 30 some were hard to chamber but we're pretty accurate at 25yards had the opportunity to shoot another batch yesterday they were very hard to chamber in the Warp and spiraled really bad when I shot them at 50 yards. I had shot some of the 1st batch in my Troy Manny QB78 the first batch chambered easy in it an grouped well at 25 yards I'll try some of the second batch in it today and see how they do in it.

Update on my post I tried the second batch pellets in my TM 30 they chambered easy and shot well at 50yds I think they'd have been tighter if I had a different scope on it, the Hawke deer pass has a circle cross hair.  I tried them in the Warp again still hard to chamber them an accuracy wasn't very good, I then shot JSB 44.75 they chambered easy and shot a one hole group at 50yds. I used my caliphers  on them an the cast are .07 longer than the JSB

Sounds like the chamber in the WARP is too short/tight and/or too short a leade for the heavier/longer pellets.... Can you post a group from 50 yards with the TM 30....

Re: .30 cal Heavy Pellet from NOE - My First Castings
« Reply #59 on: March 25, 2018, 08:17:43 PM »
I finally had a chance to pour some pellets today.... Al surprised me by sending everyone a fourth set of pins to make a flat base, 73 gr. pellet as well.... I cast all four versions, and here is what they look like.... Virtually all of the solid base pellets were great, but about half the skirted pellets got tossed back into the pot because the back edge of the skirt had a slight notch from improper fill-out (regardless of the skirt depth).... This was despite running the pot at over 800*F, preheating the mold, and using a fast tempo while casting.... It looks like these pellets will take a while to learn the best technique.... but I'm sure I can reduce the reject rate with practice....



I used 40:1 lead/tin (2.5% tin) and got the following weights....

Deep base pin = 59.3 gr.
Medium base pin = 62.9 gr.
Shallow base pin = 65.7 gr.
Flat base pin = 73.3 gr.

I tethered my .30 cal BRod at 2900 psi, and adjusted the velocity so that the 59 gr. pellet was just under 1000 fps, and got the following for a 5 shot average.... I shot some 50.2 gr. JSBs for comparison.... The chambering effort for the 59 gr. was no different than the JSB, but as the weight increased and the bolt probe pushed the pellet deeper into the throat of the chamber, the effort went up a bit.... However, even the 73 gr. solid chambered in my TJ's barrel just fine, and at 0.301" groove it is tighter than most .30 cal airgun barrels.... so I don't anticipate anyone having chambering issues....

59 gr. = 987 fps (128 FPE)
63 gr. = 944 fps (124 FPE)
66 gr. = 955 fps (133 FPE)
73 gr. = 881 fps (126 FPE)
50 gr. JSB = 1039 fps (120 FPE)

For some reason the 63 gr. (medium base pin) pellets were a bit down on velocity compared to the 66 gr.... The bolt probe in this gun is 0.109", so smaller than the bottom of the recess in the deepest skirt, so the loading depths should progress in a logical order, with the flat base loading the deepest and the lightest pellet the shallowest, so I don't think that is the reason.... This leaves me to conclude that the shallowest base (the 66 gr. pellet), and of course the solid, flat base (73 gr.) are not obturating in the same way, and have less friction as they travel down the bore.... I'm sure the are sealing fine, because the back of the skirt is 0.308", and the head is 0.301".... but it is likely that the deep and medium base pellet skirts are blowing out a bit from the air pressure (as is normal for pellets) which is adding some bore drag.... I can't think of any other reason that the 66 gr. pellet should shoot faster than the 63 gr.... but it did so consistently in this gun....

My backstop inside my shop is only 20 ft. away, but I can usually spot pellets that aren't promising because groups don't just leave one ragged hole at that distance.... In this case, all 5 pellets tested, the JSB and all 4 weights of the NOE pellets, left just one ragged hole about 1/2" OD, with no consistent variation between the different weights.... I am hopeful they will provide good accuracy at range.... but is it very likely that others will get a chance to find out long before I do.... The nice thing is that by tethering my BRod at 2900 psi I have enough power to drive any of these weights into the mid 900s, even the 73 gr. solid....
