The 250Airlln, is just a handle I put on a 250 Sav AI 307 brass for rim, and the neck left long after sizing in the 250 ai dies. I'm not sur how much it may differ from the Bowers.
The 6.5 is 7x57R brass necked down with 6.5-257Rob. AI dies.
The .250 is 15 7/8" and the 6.5 is 17 3/4'
Both are Pac-Nor Super Match blanks, and both built by Mike Sirois of OTT( On Target Technologies in Dover NH.

Hmmm...did somebody say "250 Savage"? In a Pistola? Yet another wildcat based on the "obsolete" 250. 8) Very nice!!! Looks like a deer gun for Minesotas slug country to me. I assume those a 100 yd groups. If I saw correctly 2700 FPS. Very impressive!! CL

Yes on all accounts cloverleaf,,,sorta( cept for the very first string top left to make sure I was on paper). The 250 was put together for use on antelope in mind and the 6.5 for for the deer. But the 6.5 wasnt done in time, so i worked up loads with th 110's in the .250 for deer. And yes, it impressed me too! both of them for tha matter. I got a gut feelin that 130 gr Accubonds will out shoot the Partitions, and thos are sub moa.

Pop, the .250 does 2800+ with 100's and I stuck with the 2700 fps on the 110's. The pic of the 6.5 target and 125 gr NPT's were 2800, and 2825 avg.. I haven't tried them yet, but when I had it built the theoretical load was 130 gr AB at 2650-2700 fps,,,I'm sure it'll do 2700 easy.POP":359n8e0w said:

Very nice Dave, very nice indeed.
I am bettin either one will put the hurt on a Pronghorn or Deer.
Several years ago I had a SSK Contender Barrel, 14" Stainless-Steel in .250 Savage. I was shooting 100gr. Nosler Ballistic Tips at 2650 FPS. I did manage to take one Whitetail Buck with that barrel and load before a buddy talked me out of it.
Good luck huntin with those beautiful T/C's.

Here's a pic of the .250airln
left > right
new .307 brass; stepped down partial sized in a 7-08 then .260, then regular .250 dies, with a final shoulder bump with the 250 ai dies;
fully fireformed in my chamber; regular .250 Sav. AI; .250 AI-307 standard neck length. I had received a few of the 250-307AI's from a friend which I stuffed with the 110's for seating depth dummies wich were sent along with my die for Mike to make the chamber from. He EDM's the chamber, to each die. So virtually they can very well be one of kind match chambers.
another pic of my loaded round compared to a regular neck
It's an awesome little round, and not finicky to feed. 100 grainer BT's loves RL-15 and shoot better than the 110's averaging goups in the low 3's

That is awsome dude allthough I'm a 2508 improved man myself. One of these days I'm gonna hafta get me a fluted barrel like those. I'm also leaning toward forearms that are wider and flatter on the bottom for stability . I admire your taste 8) 8)

Good to see you here onesonek. There are only a few SP guys on this site. I wish there were more. This site is great for load data and shooting knowledge. Those are some good groups. I hope to add the Encore platform to my SP addiction soon.

Thanks POP. it is somewhat ivolved forming process, but I don't think it would have to be. going It just seems easier to do it in an extra step down. Right, wrong, or indifferent, normally I anneal after .025-.030 before going down anymore. But the way I been doing it I haven't gotten any wrinkles, and anneal after fireforming.
Actually, Thanks to All!
Dave
