NOE 250-27-RF

[EdinGa]

I had a good first session with my new mold. I scrubbed it down with dish soap and an old toothbrush then heat cycled it 3 times in my powder coat oven. I cast 125 and ended up with 32 culls, but I was being super critical with them. I really want to see just how accurate they can be. These are powder coated and sized to .250.

Did you size the skirts too?.... They are supposed to be larger than the head by about 0.007"....

Yes, I ran them all through my NOE .250 air rifle bushing. I didn't realize there was a difference in the measurements. Thank you for the information. I did a quick 30 yard group this morning and they seem promising so far, but I will definitely try them unsized next time.

I've got the same mold. I originally bought it for my Sumatra but the skirts were too small to hold in the magazine. I'm just starting out with using them in my sentry 705. Finally got a shot string so I know where to start with the pressure and where to end so we'll see how they do accuracy wise.

I shot these into water and recovered them. There's barely any rifling marks on the skirts. The rest are going back in the pot to be recast. I'll powder coat a few and lube the others. No sizing this time.

I've never resized my cast pellets just my slugs.

My .250-22-WC actually shoot better in my Diana Bandit if I resize them.

I received this mold Monday, haven't had the time to do more than just open the box.

I think we need to build a sizer that will shrink the head and open the tail, then push them back out the entry end of the die.

I had time to cast a few more this afternoon. These were shot as cast and lubed with Ballistol. I had been shooting them sized and powder coated, so I'm considering this a seasoning group. The first 2 went right then it shifted land gradually climbed until the last 4 went into the big hole. It was too dark to shoot anymore so more testing tomorrow.

Hi Greg,

I noticed something about some of the holes in your target:  Unless the target material was not flat, some of your pellets may be yawing.  Notice where the skirt cut the paper, relative to the head in the enlarged image of your target below:

I have no explanation for this, except that the target was probably curved near the point of impact.  If not, something else is going on.

Compare the cropped image with your original to exclude possible bias in my skirt edge demarcation...

That is what my sizer does, I can size the head only, (whatever size needed, shrink or expand) or size the head and skirt,
with 1 pull of the handle etc.
I have  posted info/photo's of it somewhere on this site, but can't find the info when needed, very poor search dog etc.............

Don,

I'll send you the bill for finding your post for you

Thanks Terry
The only problem is, I don't know how I did it,
after 6+ hrs of clicking this and that etc. LOL

But here they are.

Bare press with no attachments.



Forming parts for press,
L>R , skirt base pin, nose HP pin, adjustment screw from press,
top> NOE size die, die holder for press, NOE die sets inside die holder 1 st model,
2nd model (bottom) Noe die sets on top of die holder, better option



A close up of the same parts as photo #2.



Parts mounted in the press, 2nd die holder style.



HP pin inside OEM adjustment screw.



L>R, sectioned pellet bases, OEM Crosman Piranha, reformed pellet skirt,
group of 5 pellets showing the reformed heads, skirts, reformed HP, OEM pellet HP,
notice the different sizing dimensions of the skirts/head, via different pressure used.



Close up resized pellets using different pressure, OEM pellet in the middle.

And a simpler differential head/skirt setup with cheaper home made dies:

You have a very good eye. I moved my bench earlier in the day to get out of the sun. By the time I shot this group, it was getting dark and I was in a rush. I was shooting at an angle to the target. The cardboard was only pinned at the top too. I'm sure that also contributed.

You have a very good eye.

I see things that other people miss, or see but don't register. 

I once walker hastily past a rack of freshly painted shock absorbers in the development bay, when I worked at Gabriel, over three decades ago.  From 15 feet away in full stride, I noticed that two dampers were "different".  That was enough to make me take a closer look.  The reinforcement welds holding on the mounting rings were missing on those two damper endcaps. 

I can't help it...  It has to do with pattern recognition.  Anything that breaks a pattern screams at me to pay attention...

All of your comments are appreciated and welcome. Thank you again.

Initial results seem to indicate that I should be casting with cavities 2 and 4 of my mold. What say you? More testing to come though.

Both shots that are outside of the main group on 2 and 4 were the first ones out of a fresh mag. Not sure what to make of that except shooter error.

30 yards

I've got the same problem ☺️ I wet my wife off all of the time when I see things like that and tell her. She just can't see it.

Wet?  I think this may be a case of the forum software being so eager to avoid naughty words that it might just have made it sound worse.  This is a pet peeve of mine:  machines correcting language, in a context they do not understand.  If the protectors of virtue want to do a good job, then they should be looking at phrases and replacing them.  Not words, out of context. 

Imagine the machines putting words into your mouth, that then become evidence of intent in a criminal case?  Intent that was never actually expressed...
