25-21 Bullets or Mold, 100gr
Nov 7th, 2014 at 5:34pm

Have sent a request to Dave Bennett for his Schuetzen bullets.  Next reloads for the CPA 25-21 will be 200yds, the reason for the 100gr bullets

Advice for other 100gr bullets and/or mold would be appreciated - Thanks

Use a Hoch from CPA in my 25-21.  AA #9 powder and small pistol primer in a RMC case.  Bullet is about 105 grains.  Good conditions, it does very well at 200 yds. however, it is wind sensitive.  Great turkey rifle.

A 100gr being wind sensitive, looks like I better run the weight though the Powley calculator to determine if I can use a heavier bullet and if it is within pressure and stability for a 25-21.
The reason I brought up a 100gr is because in Sharpe's Handloader book, the Shoyen 100gr bullet is listed
38-55, Thanks for your experience with the Hoch

John Boy, I have to agree with 38-55 in that the Hoch .258/105 mold is casting a bullet that is super. My factory org. Stevens 44 in 25-20SS was anything but accurate till I started breech seating the Hoch bullet. The AA#9 powder and IMR4227 is working well for me also. However I use Federal 205M primers. That Hoch bullet is the only bullet that my rifle will shoot under an inch at 100 yards. At 200 yards it is still shooting accurate but shows slight tipping from my rifles 1 in 13" twist.

38-55 or Sendro ... would you do me a kind favor for the Hoch bullet:
* OAL
* Wt = 100 or 105gr?
* Dia
* Alloy
My CPA Douglas barrel is 1:12 twist for the 25-21.  With the measurements of the Hoch bullet, I can plug in the bullet numbers and Cx the fps and minimum twist using Dell's formula and Powley's calculator
Thanks Kindly

Ballards may be weaker,

I'm using an old NEI mold I got back when he was here in Scappose, Or. and it drops a 102 gr. bullet. It's a plain base, and has two large grease grooves, and a crimp groove. I don't use the crimp groove for my fixed loads. I'm shooting a Stevens 44.5 with factory Stevens barrel. I believe NEI still offers this mold, if you don't mind aluminum molds.

John Boy, the Hoch mold that I have throws a bullet that weighs in at 107.5 gr. when I cast with 1 to 24 alloy. It is .251" on the front band and .258 at the base. It measures in length .858" long and has 5 grooves. I breech seat this bullet with a plugged case that sets the base of the bullet so that the lands cut about 1/2 way through the base. It is stable in my 1 in 13" twist org. Stevens 44 factory barrel at 1340FPS and have pushed it to 1550 fps.

what are the pros and cons between the 25-20 SS and the 25-21?
  I have 2 rifles chambered on 25-20ss one a custom barreled Ruger #1 another a relined Rem#2

I have a third that MAY wind up relined to one of the .25 cal, a nice solid little German break-open stalking rifle, as a small game stalking rifle rather than a 100/200 yard target rifle.

IS the difference mainly in twist rate and bullet weight?
Are appropriate liners available in differing twist rates?


I'm assuming that case availability might be a concern too

Sendaro - Thanks Kindly for detail information.  Printed it and next step is see what the calculations say

QM, lets start with the bad news that might be an influencing factor:  100 Rocky Mountain Cartridge cases with shipping - $210! They are excellent brass compared to Bertram's junk... 39 of 40 cases split complete length on 1st shooting to the tune $164 plus shipping

As for the pros & cons between the 2 calibers, I can only speak to the 25-21. CH4D is sole source for the $110 dies, the seating die was redone by them for free because with an 85gr bullet with no compression - die wouldn't seat 85gr bullets to the bottom of the driving band.  Plus, I clean them by hand because the cases taper so thin to the mouth I'm afraid to put them in the rotary tumbler
In a 1:12, so far @ 100yds with 85gr bullets though, - accurate and fun to shoot with zero recoil

The biggest drawback to my .25-21 is case availability and cost. I haven't tried making them yet, but have read of several people who made them successfully from .223 brass turned down at the base to allow reforming.
I read somewhere that the .25-21 was introduced after the .25-20SS, as the black powder shooters wanted a straight wall case that burned the BP better than the bottleneck .25-20SS did. With smokeless powders, the two cases are pretty equal.
