« on: December 11, 2016, 02:55:49 PM »
 I have acquired three rifles In .25 souper looking for anyone with experience or load data for this caliber. I already have the dies just looking for some help so I can get some ammo loaded up and go shoot them.

Ballisticstudies.com has a nice write up on your 25-08.States that it beats the 257 roberts and the 243,260. Use 4350 powder with nosler 115 gr on deer sized game out to 500 yrd. Coyotes wont like the 75 grainers either.Tip for brass is use 243 or 260 as neck thickness can be a problem if necking down 308's.Hope this helps.

" In today's instant gratification society, more and more pressure revolves around success and the measurement of one's prowess as a hunter by inches on a score chart or field photos produced on social media. Don't fall into the trap. Hunting is-and always will be- about the hunt, the adventure, the views, and time spent with close friends and family. " Ryan Hatfield

Here's discussion fro 24hourcampfire on the 25 Souper with some data.

http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/6562790/1

I looked seriously at the Souper before I built my 25-204 Ruger(257 Kimber/25x222 RM Improved) and found I could get all the performance I needed for deer hunting in the smaller cartridge, 100gr partition at 2850 fps.

And it worked as expected.

After the first shot the rest are just noise.

The 25 Souper is a pretty cool round. Performance wise it will be just behind the 257 Roberts all else being equal. I measured a 257 Roberts case and it holds 56 grains of water compared to 53 grains for a 243 case. For load data I would use 257 Roberts data and just limit the charges to 90-95% of max.
