I use 4 grains of Tite Group with a 86 grain Remington jacketed flat point .257 dia, 1400fps, 30fps variance. It works good thru just my powder measure. Accuracy is good. When I go beyond 4 grains I see case issues. Not a recommendation, just what I do. T/R
Hey all, I’m trying to get that 25-20SS going, 86 grains cast lead did terrible with 4.7 of Unique. Jacketed 87 gr rounds manufactured by Jamison did very well.
Now I have some 76 gr jacketed flat points. I have little powder available, just some Unique and Universal, some old 4350 and Win 231, Titegroup, and a few others.
I’ve heard mixed reviews of using Unique. Too fast they say. Is there a load known for 4350? What would you use with Titegroup for 76 grain jacketed?

IMR or H 4350? I’ll look through some of my manuals. I often don’t get good results with Unique or Bullseye. I do use them though.

Not that I can find listed–too slow, I assume. 4227 is a powder widely recommended. With so many components stupid-priced, or unavailable, you may be forced to use what you’ve got.

4350 is best suited for medium sized cases with heavy projectiles (example being .243 Win with a 100 grn. projectile) or large case capacity with with light to medium weight bullets (example being 8mm Remington magnum with a 150 grain projectile)

Thanks, I lucked into a can of Accurate 1680 and will be trying that.
From this thread, it was recommended for lead 86gr bullets to use 8.5gr 1680
I’m also going to try it with my 75gr Jacketed bullets. In the Accurate manual it says 11.1 grains starting for the 25-20 WCF, not the SS. Should I go that high, or back off a little to 10 grains?
The 11.1 grain load listed in your Accurate manual will be perfectly fine in your low-wall.

I’ve reloaded .25-20 and prefer to use 60 gr. I’ve often wondered if .25 air rifle pellets (25-30 gr.) can can be loaded in .25-20 cases using only a primer or small amounts of powder. Has anyone tried/done this? Results? Thanks.

A simple experiment to try, but usual problem with drastically reduced loads is poor accuracy.
Thanks Clarence. .25 air rifle goes around 950-1,000 fps. What powder and amount would be a good starting load? Also, twist rate with Savage 23b vs air rifle would be a factor as well.
Hey Bert H. any advice on loads for the 25-20 SS w/ 85 grain hard cast bullets?

8.5 grains of 2400 or 8.5 grains 4227 both shoot well in my low-wall. I am getting ready to experiment with using Hodgdon’s Lil’Gun powder.

Thanks Bert,
Yeah that’s a great article, and I’ve tried a couple of the loads mentioned, I just wondered if you had something strange worked up. I think I’ll try 5 grains of
Bullseye behind an 85 grain jacketed bullet.
regards,

When I get the load worked up with Hodgdon Lil ‘Gun I will post it.

From what I’ve read about Lil’Gun powder, I wonder if it’s detrimental to the steel in these vintage rifle barrels. Freedom Arms does not recommend its use in any of their revolvers due to premature forcing cone erosion. Whether this is only a problem for revolvers or translates to barrels without cylinder gaps I do not know. Therefore, I am hesitant to use it before I know for sure. Of course I discovered this potential issue after I bought an 8 pound jug of it. I may have my son use it for loading his 300 Blackout in an AR barrel that can easily and cheaply be replaced. Does anyone have any knowledge about possible damage that Lil’Gun powder may inflict?

A large number of 22 Hornet (and K-Hornet) reloaders are using it and loving it. I have not heard of any premature barrel throat erosion. Based on Hodgdon’s published load data, it produces less pressure that other traditional powders, but with slightly better velocities.
Because the 25-20 S.S. case is essentially an oversized 22 Hornet, I believe that the Lil ‘Gun powder will work in it as well. I will be shooting it in a Winchester Single Shot with a 28-inch barrel. There should be no issue no issue with barrel erosion.

Dimrod-
It’s my understanding barrel throat erosion is generally most common in overbore cartridges so I wouldn’t expect to find it in this cartridge or most revolver cartridges. I can’t imagine being able to get enough powder into a 25-20 SS case to cause significant barrel throat erosion but I have no experience with this cartridge or powder. It’s just that barrel erosion is a function of a large amount of powder going through a relatively small bore. I’d like to see more documentation from Freedom Arms, doesn’t seem to add up for me. I know many of Hodgdon’s newer powders are supposed to be cooler burning but Lil’ Gun has been around for awhile.

I have a Winchester model 53 in 25-20. It took a few weeks to assemble the brass from a couple of fellows and I received my order from Montana Bullet Works for their 85gr. gas checked bullet.
I loaded up a few rounds using the different loads recommended in the Lyman Cast Bullet Handbook for the 85 gr. bullet.
At the range and at 50yds. most of the groups were about the same for the little 85gr. bullet. I chose 2 of the smaller grouped rounds to reload for another test. All shots grouped at about 6″ low. Ok I can adjust the back sight next time out!
I had ordered, and received Ken Waters two book set, “Ken Waters Pet Loads” in the mean time. Reading the section on the 25-20 I noticed he had shot a very accurate load in his Winchester 1892 using an 85 gr. bullet. H-110 8.5 gr, 85gr. bullet, Magnum CCI small primers. I had the components so I loaded up a few.
Next trip to the range the Ken Waters load grouped much better than the two other loads I had tried and raised the group to hit the center of the bullseye. No sight change needed. With 79 year old eyes and a fuzzy target I am pleased with the results!
