Would anyone have any load data for the 25-35imp. I would like to use 100gr - 117gr spire points if possible. Thanks.

I have a fair amount of high performance data from my 24" TC Contender. 100 grain bullets were my main bullet as I am shooting West Texas White tail.
The 75 grain SIerra Jhp is a very good varmint bullet in my rifle.
I have posted quite a bit about the cartridge on the Beartooth Shooters forum.

What rifle do you have?
My barrel is a 1-8" twist. I would like to try a 1-10" twist as old writing from the 1920's and '30's has some good reports.
Greg Mushial from GMDR has a rather slow twist .25-35 WCF barrel and he shot light weight cast and jacketed bullets very well with it. He has a fair amount of cast bullet data for the Improved cartridge on his web site.

If you dont have your rifle yet consider the .25-35 Tomcat which is a mild Improvement and a very interesting cartridge.

Thanks william_iorg. I hadn't seen you much since I don't frequent that other board much any more. Be Well, RZ.

Mine is a Savage 99. Originally it was a 22hp but it was bored out to a 25-35imp. It has a 1:10 twist. I would like to use 100 gr Rem corelokts since i have a bunch of them.

Rusty,

I was looking at somthing Violator 22 posted – he made a .25-35AI Model 99 for his daughter using an 18” barrel.

Thinking on this I am wondering about the age of your rifle. You may not want to run the highest pressure loads in your rifle.

Back in the 1920’s J.R Mattern, Townsend Whelen, Paul Estey, Al Barr and a few others wrote of the .25-35 in terms we do not read about today. Back in those days the 100 grain bullet at 2,400 to 2,500 fps were commonly discussed as deer and varmint loads.

I regularly shoot the 100 grain bullets in my 20” Winchester model 94AE at 2,550fps+ with no ill effects. I have never experienced sticky extraction and believe I have not lost a case in several years.

J. R. Mattern considered the 100 grain bullet at 2,400 fps to be ideal for deer.

Robert Hutton developed several loads for P.O. Ackley using 100 grains bullets at 2,400 fps from 29.0 grains of IMR 4895 – this in a 26” barrel Mauser I believe.

The Ideal Handbook No. 35 (1948) lists loads using 27.0 grains of IMR 3031 driving the 100 grain bullets to 2,450 fps.

In my standard .25-35 28.0 grains of Alliant Reloder 15 will just nudge 2,450fps using the bulk 100 grain Remington PSP.

Paul Estey used 28.6 grains of DuPont 17 ½ for 2,450 fps with the 100 grain bullet. This in a Sedgley Krag with 24” barrel

I am taking the long road to ask what your velocity goals are with the 100 grain bullets.

My goal in the standard .25-35 was 2,500 fps which I achieved with no difficulty. I primarily use the Speer 100 JHP which I feed through the magazine with no difficulty. This bullet was designed as a varmint bullet for the .257 Weatherby.

The 100 grain Speer JHP performs very well on West Texas deer (my furthest shot to date was just a bit over 125 yards). I prefer the Speer JHP to the 110 grain Hornady FTX bullet. The FTX bullets expand quickly and in my experience tend to wad up as they penetrate. The Hornady holds its weight pretty well but other bullets will out penetrate it.

With the standard .25-35 you can easily reach 2,600 fps without difficulty. 26.0 grains of Alliant Reloder 10x is a pretty good load which does the deed.

 

Getting back to the Improved load. I like the Improved case in the Contender as it eliminated sticky extraction.

Hodgdon 4895 is a good powder to start with. In my 24” Contender 31.0 grains of Hodgdon 4895 will push the 100 grain Remington bullets 2,525 fps and break the magic inch for 5 shots on most occasions. It pretty good shooting for bulk bullets.

32.0 grains of Hodgdon 4895 will get 2,617 to 2,625 fps but group size increases about ½” for 5 shots. If your rifle is anything like mine I predict you find happiness between 32.0 and 33.0 grains of Hodgdon 4895.

My father insisted I would be happy with 2,700 fps and he was right. If your barrel is 22” or longer you should have little trouble reaching this velocity with good case life. I use only new .30-30 cases to form.

Thanks for all the data William. I dont want to run it super hot. Just looking for a deer load for 100yrds or under. I was hoping to use H4895 so i will try the loads you posted. Much appreciated.

Dont overlook IMR 4320 which may be the best powder for the .25-35's.

I shot a great group today using 25.5 4064 using 100gr Rem Corelokts.

IMR 4064 is a powder I did not experiment much with.
The interesting thing about your results is found in the April 1980 issue of the American Rifleman. They were testing the TC Contender 10 inch barrel in the standard .25-35 WCF.
In the standard .25-35 WCF with 10 inch barrel, 25.2 grains of IMR 4064 behind the 100 grain Speer JSP developed 1,875 fps with 37,000 CUP.

You might want to look at 25 Bullberry and 25 Bullberry Imp. data.

25 Bullberry = .25 x .30-30

When I acquired my German cape rifle several years ago, william_iorg was a wealth of information for 25-35/6.5x52r reloading data. I cannot thank him enough for helping me with this effort. Good people.

Thanks for the replies. Sorry i havent checked in for awhile. I ended up going with 29.5gr of H4895 and the Speer 100gr spitzers. They are discontinued but i managed to find 400 of them online. The 100gr Rem Core Lokts shoot just as well and im sitting on 500+ of them also. Im getting 2640 fps from this load and shooting 1” groups at 50yrds and 1 1/4 groups at 100 yrds. Good enough for a deer load in my area of Pa.
