Scale should arrive today. Also got help on another board to confirm Greenwood's book does show a load of 3.0 grains of Unique for the 297/250. I'll wait on the scale and load lighter charges as they seem to be recommended as more accurate.

Greenwood's book does say 3gr of Unique is a good load.
He also says 25cal. pistol bullets are suitable so that is a big help too.

Happy to report I was able to load up 5 different loads and get to the range yesterday.
I was using lead round nose 25 ACP bullets, cast by Bear Creek Supply. Loads with 1.9grains of Unique were accurate and showed no pressure signs. Hotter loads with 2.7gr Unique showed issues with cratered primers and sticky opening, so I'll be tearing those down to re-do with lighter charges (including trying 1.7gr Unique).
I did not try shooting any of the jacketed round nose 25 ACP projectiles from PPU, as I had those over 2.7gr Unique and I'd already seen issues with that much powder and LRN bullets.
Remington 6/12 primers seemed to give better accuracy than regular small rifle primers. Will need a bigger sample to confirm.
No difference I could see between RMC turned brass cases and reformed cases made from 22 Hornet brass.

Chris,
This is a nice report. I find it interesting that your accurate load of 1.9 gr Unique was much less than the load of 3.0 gr Unique as recommended by Greenwood.
I used the Greenwood recommended load of 5.0 gr of Unique in my 295 rook and found that the load was way to hot for my gun.

Here's my 250 Rook. ... It's an alligator cased Watson Brothers. I love that caliber. I have several 250s, this is my best one.

you .250 rock guys maybe not notice this, Händler& Natermann in germany is making 6,35 mm airgun slugs
for some time now called "heavy slug". weight of this bullets goes from 38 to 46 grains, they differ in length but be otherwise the same.
https://www.hn-sport.de/de/air-gun-hunting
hollow point with flat base, pure lead, diameter .251
25 ACP full metall have .250
the heavy slugs cost 8-9 euro for 100 here. they work fine when reload them into 25 ACP.
of course, the 46 grains is the best for the pistol rounds. the bullets are not coated but lee liquid alox will do it - if you can get this bullets in your country.

Very nice piece of kit Buckstix!.
Hopefully you can get some of Lancaster's air rifle slugs - they'd be just dandy!

look at my boxes, they are available in more different weights
here is a 28 grain , 36 grain and 44 grain bullet
the 5,5 mm could be maybe useful for reloading the little .297/.230 Morris

That is a great find, and in a great, useful calibre.
I have always used a 56 grain bullet cast here in England with soft lead, at just under the speed of sound - 1100 fps or so.

Hello 93x64mm,
I have bullet swaging dies for 251 cal so I can swage lead and jacketed bullets from 30g up to 65g.

How difficult and expensive is it to get into swaging?

you can use a reloading press like the rock chucker for such small bullets. problem is you need lead pellets with the right weight, length and +/- a special diameter. common way is to have lead wire and a cutter for making them.

Hello,
Start-up is a little pricey, but well worth it. I have 4 Corbin swage presses.
http://www.corbins.com/bullets.htm
Over the years I have acquired swage dies for 20 different calibers from .14 cal up to .460 cal. I've paid for much of the costs of dies and presses by selling custom bullets to others.

A friend just boughht a corbin press to make slugs for his PCP air gun. It does a great job.
I don't see used Corbin presses coming up for sale so I guess the buyers don't sell their old presses or I am looking on the wrong website.
