Some day I will have a 25 souper.
I have found some limited data on it online.
Never seen anything on an improved version.

i was reading an article on one then an switched pages.. 'dumb'... when i tried to go back i lost it never did find it again, but here is what i got left of it... James Patric; Shooting The 25 Souper Improved; Precision Shooting, May 1998; pp. 35-42. what i remember or thinki do is it is actually called a .25-243 improved ?

there is in the #10 an 11 volume of cartridges of the world a small write-up of the 25 humdinger in the wildcat section, .. i believe or want to believe its the same cartridge i'm thinking of building -- 25-308 AI

when i mention of building this thing it seem most all revert me to a simpler deal.. to either buying a .260 cal or making a .257 AI..
somehow i see more potential in my project version

If I were looking to build a .25 wildcat I would either use the 6mm Remington case (AI'd) or I would go with the 284 Win case, leaning toward the 25-284.

Jamie i think i'd need a long action for the 25 284
i have this question on loadin data in few different places .. i can't believe i'm the only one either thinking of or have since built a rifle on one of these cartridges

I will snag a .25 cal bullet from my buddy today (.257 AI Sako pistol) and load it into one of my 284 cases. The 142 SMK from the 6.5 is a little long to fit in my short action Rem but that is why people use the 6.5's. I think that with the .25 you would be able to use the 284 case. If not, then as Calvon reminded me, go with the .257 AI.

Then that is what you should build. Practicality has less importance when we want a project - it would certainly be more "practical" to build a quality .260, .257AI or .25 WSSM. The latter two would have a higher velocity potentials compared to the .25 Souper - but velocity is not the end-all of rifle performance. Too many shooters get caught up in the velocity race - I wonder how many of those who recommended the .25-284 to you for its high velocity will turn around and bad-mouth the .338 RUM for being "too much". ;)

Seems like the only thing that was being "bad mouthed" here was me by you.

The 100 grn BT in the 25-284 (yep, I made one up for you to check) load so the base of the bullet is at the bottom of the neck is just a hair too long for the short action. So you are right, it won't work in the short action. If you want to go with the 25 Souper, build it. From everything I can find the Souper is real similar to the 257 AI.

Why not go with a .257 AI? It will have abt the same case capacity ie. velocity, dies will be alot cheaper, there is alot of loading data for it, and there is no necking down to do.

Thanks Jamie, i thought that.. the other part of that was extending the bullet into the lands .. would even make it wors'err...
i think i have found two case dimensions that are very similar for what i want project wise .... is the 257 durham jet an the .250 humdinger which is so close to the improved 25souper turns out the shoulder angle is about 45* which lenghtens the neck a little more the souper at 35*

catfish has about a close to the as easy as it gets an your rite its the easy out but.. as italians are known to be thick.. and i is !
the problem with the humdinger is there may be only four made since 1998 an to get the info i'm search for is like pulling teeth
still in the planning stage an i could change my mind before it all comes together

Jamie i had no intentions on starting an flames with quote

No worries. You didn't start any flames, just a dumb comment by someone else. I understand wanting something totally different, just sometimes it is a pain in the butt and we want to make sure someone knows what they are getting into. Post pics of whichever you end up with. I think they are all close enough that it just comes down to what name you want to tell people you have.

working to what i want to illuminate .. i have 4 700 hb 26" 223P 22-250 243 308P all new an shot very little. .. this project is to put a bullet/cartridge between 223 an 308.. the 223 shoot up to a 77gr match sierra very accurately.. the 308 will shoot down to 110 grn bullet which i haven't shot any for testing yet.. so the plan was find one to build that has a lite enough varmint weight an heavey enought deer size bullet that will back up either rifle... the .25 cal will shoot 60grn to 120grn .. as you say " it just comes down to what name you want " "the plan".. is to have the 243 an 22-250 pay for the wild cat which also leaves me two leupold scopes left over, kinda makes sense in my mind.. although a buddie of mine says i'm nuts ... so go figure, what works for one doesn't usually work for another..

It makes sense to me also. I am currently thinking along the same lines, although I may take the easier route with the .260ai or 243ai. I have a 700 hb in 22-250 with the "P" style stock (heavy palm swell black w/ green spider webbing). Or pick up a Stevens 200 long action (25-284, 6mm-284, or 6mm-06ai )and add a Shillen barrel and B&C Tactical/Varmint stock. Just haven't decided which way to go yet. Get yours done so you can give me some good feedback. I hope it all works out like you want.

Thanks Jamie... if i get it done i'll update .. thinking along my line of thought you mite wanna save the 22-250, unless it doesn't shoot well or the barrel is shot.. go with the savage/stevens.. out of the box all i hear is they are more accurate then the rems, but more important is to have a back piece or a gap filler... anyways i just got got some news that really good info is being sent to me on the hum""" if its as good as hope i'll be looking for a smitty next week..... will see !!

I attempted to reply to this topic previously, but dont think I was sucessful in getting it on here,..However,..18 years being involved with the standard souper,..ha snow led me to AI my second souper,...a friend has owned the latter for 12 years, and finds a load of 45 grains of reloader 17 with a sierra 100 gr. gameking a good recipee,...brass,= knecked up 243 nORMA BRASS,.. federal primers,..26" barrel number #3 profile,..gives a accurate velocity of 3200 FPS,..However I would recommend starting 2 grains below this and coming up in half grain loads to see what agrees with the rifle you use,..

I hope this is a help,..

regards and happy shooting,


Naki Shooter
