Hello everyone
Thanks for looking at my post.I have just converted a Stevens model #12 in 25 rim fire to center fire and re- chambered it to 25-20 wcf
Covid lock down gives a fella spare time to burn in his basement !In short it key holes 87 gr. Bullets at 50 yrds as I thought it would.
,Shoots 65 gr hornady bullets pretty fair.I read that there is a approximate 50 gr HP bullet mold possibly for air rifles.
I like to purchase even 5 – 10 bullets to test before I purchase a mold.
If anyone might be willing to drop any bullets 65 gr. or less in a bubble envelope in the mail I’d pay for the bullets , postage , envelope and your time.
I live in ontario Canada.
Thanks for your time.

I’de love to help you,… but to send bullets to Canada from the US basically one now needs an export license… to get the package in question through Canadian customs… and I understand that the Canadians on the receiving end also need the corresponding import license to not get into trouble with you own government…
President Obama placed an embargo on bullets & other reloading components to Canada when he was President and Canada responded by placing an embargo right back… on the US… in kind…
I would if I were you… address my request for some samples to your other Canadian shooters…. that way you won’t get into trouble with your government.
Otherwise I would have been more than happy to send you samples…
It is why Canadian distributors North of the Canadian border now say that they will not ship to the United States in their advertisements… even if they have product that we want in the United States, & we have product that the Canadians want…
It is what it is…
Do you know the twist on your 25-20 barrel?
Attached is the Shilen 25 caliber barrel twist rates vs bullet weights…
BTW air gun is basically .250 -.251
25-20 is a .257 diameter bullet…
it might possibly help explain why your heavier cast bullets are not stable for you…
Take Care, & Stay Safe…
I have been thinking overnight about your original email verbiage…
It leads me to believe that you must not have changed the original barrel out on the Stevens 25 Rimfire, just rechambered it to 25-20.
I believe that you will find… or already knew… that the original rimfire Stevens was a 25 Rimfire which was an inside lubed cartridge design… which is probably why you asked about getting some air gun cast bullets…
Unlike the original & current 22 caliber rimfire cartridges which are basically a heeled bullet design… thus the original Stevens rifle barrel is much closer to 6.3 MM (.250) than a true 25-20, which is a .257 animal… and much closer to a 6.5 MM caliber… speaking in metric diameters.
That 25 rimfire cartridge was from what I could find … also only offered … according to what I could find in a 67 grain load originally with Holy Black…
Later on the same bullet weight was offered with a smokeless powder load… before the cartridge itself was obsoleted out, thus limiting you to that particular cast bullet weight instead of the 80 + Gr which you found key hold on you when you tried it out.
Most all of the airgun 25 caliber moulds are of a boat tail design for the airgun, especially in the lighter cast bullet weight range that you are looking for…
Did you plan to have the boat tail airgun design posterior opened up to make a plain base bullet mould out of what ever mould that you eventually plan to buy?
Otherwise any imperfections in the base of that BT air gun cast bullet design will tend to make your accuracy go to heck in a hand basket…
Have you thought about powder coating an 6MM – 243 (.245 dia) circa 50 + Gr cast bullet design to build up the OD with the heavy Powder Coat to get you closer to a .250 diameter cast bullet that you are looking for?
Also they are more likely to be available in either a PB or GC version… of that 25-20 cartridge caliber…
A light powder coat will most probably build up the as cast diameter .001 to .002 in diameter… A heavy coat will most probably build it up even more than that, & could thus potentially get you that much closer to your original barrels needed diameter of .250 -.251 dia.
At least I tend to believe that… that will be kinder to that older rimfire barrel than I believe shooting jacketed 25 caliber (.257) dia bullets through it… would be…
You may also need to get a 25-20 set of sizing dies made or modified to reform the 25-20 necks down to the needed diameter to properly hold onto the .250 -.251 dia. bullets, or hope to find a brand of 25-20 brass that has thicker than normal case necks…
At least you may need to change out or modify the expander plug diameter to not expand the cartridge case necks back out to accept and hold tightly onto a .257 diameter bullet.
Alternately you can begin to think about getting a new barrel for that Stevens with a slightly faster twist and in a slightly larger .257 diameter configuration…
Your call on all of this …
