Who uses the 25 Souper (.25 on a 308 case)?
I really like the idea of one for my purpose, which is shooting smallish antelope (pronghorn size).
I have a lovely 243 action as a donor. The 243 Win is a little light and a 260 Rem a little slow.
I would aim for a 110 gr to 120 gr bullet at 2850 fps or so, but according to tables this is optimistic.
Any thoughts?

Here's another interesting option or you could go with a .270 Redding. Of course there's always the 7mm/08 as well.

Thanks Labman and an interesting option.
However, my requirements are more specific:
this would be for a culling rifle from stationary positions. It will wear a suppressor and needs to be accurate.
I already have a 270 for general hunting but need a replacement for the old 243, just with a bit more power.
To me this 25 fits very nicely between the 243 and 260 Rem and I am surprised that it is not more popular.

I am also surprised that the 25-08 isn't a popular thing -

always thought this was a valid missing cart

i did a 257wsm .. it was stupid fast and BORING to shoot ... the largest groups it ever made where when one adjusted the scope


opinions vary band of bubbas and STC hunting Club

Look up the .25 Creedmoor. 6.5 necked to .25. You can even buy (good luck today) brass. I am not sure of the oal though, it might require a standard length action?

While the 25 Souper is a very nice little classic wildcat cartridge, these days I'd just go with a 6,5 Creedmore, but then I've gotten lazy in my old age.

I would try to find myself a .284 or 7mm-08, but to each his own on that..a 25-284 would be a dandy wildcat in a Savage 99 IMO, but Im not much on wildcats today.

As you asked about the 25/308, not what other calibers should you use instead.....
The 260 rem with a 120 usually runs just under 3000 fps, say 2950 fps. The 25 souper with the same 120 has less base to push on, but the difference of .257 to 264 is not all that much. I would think 2850 fps would be in the ball park. As most 120's would be made for 25-06 velocities, I bet 2850 fps range would expand a little slower and cause less meat damage.

Thanks theback. I may have to accept the 260 with 120 gr bullets and not far off the Souper. I don't want to go heavier than this as this rifle will be used almost entirely as a springbuck, impala and blesbuck specialist, mainly culling from a stationary position. Accuracy is essential and it will wear a suppressor.
I have a 270 and bigger for the rest of my hunting.

I am surprised you consider the 243 a little light for that kind of shooting. I expect you are taking head/neck shots to save meat when possible?
I have a dozen or more 6.5 cartridges. I use 120 grn in all of them for deer, pronghorn, and caribou. Never saw a need for heavyer bullets then then 120's in my shooting.
I would look at bullet availability, and cost of reloading dies as factors. For the use you describe, I doubt there is any difference in performance between the 25 souper and the 260 Rem.

This 243 has been worn out by shooting springbuck and blesbuck over forty odd years so it does work, but a slightly heavier bullet will be better, especially compared to the 90 grain 243.
I liked the idea of a .25 cal 110 to 115 grain bullet but the 260's 120 will be little different.
No, mainly for body shots and the heavier bullet also bucks the wind better than the 243.
Thanks for the tips.

Karoo,
Is your 243 a short action, or a 243 built on say, a blocked mauser.
If it was me, and it's a short action, I'd go with the 260 and the 120's. I have to admit I am a 6.5 man through and through.
I have shot deer with 120 grn bullets by speer, sierra,rem corloks, and nosler. All have preformed well. Usually they exit on a broadside shot, or found under the skin on the offside.
I don't think I would bother with more then a 22 inch barrel, especially as you are going to hang a suppresser off the end.

Mine is a solid Husqvarna short action and beautifully slick.
I agree that a 22" barrel is all that is needed.

Built one on a 788 years back. Good cartridge, ballistically it was very close to my 25 WSSM or 257 AI. - dan

I think the 25 super would be a excellent choice, in that brass and bullets are easy to come by, it would be accurate as most calibers on that 308 case tend to be, and it has almost the balistic behavior of the 25-06, and you apparantly want one, how can you beat that combination!! do it. tu2

The 25 Souper has been something I always wanted to try. I think about the same capacity as the 257 Roberts, but better suited for a short action.

Gunsmith who built my LA 257 Roberts also built my hunting buddy's 25 Souper at the same time.

Spent a lot of time wagering which cartridge/rifle combo was the most accurate, even when switching between shooters.

All that got resolved was who was the better shooter, and no, I 'aint sayin who... Wink

The 25-308 should be a dandy small deer calibre. I built a 250 Sav AI. I have been using 100 gr partitions and it kills deer all out of proportion to its small case size. Nice thing about any cartridge made on a 308 case, there is a ton of brass everywhere and often for free. I also have a 25-284 which is really just a short cased 25-06. The 25-284 handles 110 thru 120 gr bullets better than the 250 AI but with bullets of 100 grs or less the 250 AI gives up very little. the 25-308 would be between these two and a very useful little round

Likewise Ive been using the little 250-3000 for over 65 or 70 years, Ive killed deer, antelope, elk, bear on this side of the big pond and all the plainsgame including Eland in Africa and it was used to kill a cow killing Leopard by a friend of mine in Zim...Its got a one shot record like no other gun in my cabinet, but has always been used with care on game, and never pushed the string on the range beyond 250 yards...Its my all time favorite caliber and has been for years and its not as good as a 30-06 or 338 but its good enough...The 25-08 should be just more of the same..
