22-250 AI info/loads

Please bare with me,I am in the process of having my Rem 700 VS changed to a switch barrel set up.I have ordered a barrel over here in Down Under for the 22-250AI.I don't want to fireform cases with projectiles,and I have heard of the cornmeal/cream of wheat method,but I don't know what 'cream of wheat' is,or how to do this process.
I have a 375 Weatherby that I fireform with pumpkin/parafin wax,but not all cases (2%) come out fully formed.
Any help will be greatly appreciated.
Thanx in advance.

Cream of wheat is breakfast Hot cereal . Ok I have the same cartridge.Here what you do: Large rifle magnum primer,10grs of unique or other fast pistol powder like Bullseye.( Just check burning rate charts) a little bit of tissue paper. Then fill the case with corn meal and seal it with wax. Load it in gun and fire. These dudes are very loud plus these are not blanks corn meal is like a shot gun pattern. For me these loads formed the cases 100%. Good day mate

hornady hydroforming dies

are the way to go, although they dont produce the sharp shoulders, sorta rounded, but the capacity is such that you can shoot your normal AI loads without any problems, then they are 100% formed........ You get a special shell holder and die assembly, put a FIRED primer in and fill with water, press all the way to cam over, hit with a hammer 3 times and presto, your ai'D


BTW I have had REALLY good luck with 44.4gr of win 760 with 55gr noslers, federal 210m primers in norma cases, producing 4030 FPS, and 15 shots @ 300m into .9 grouping......

I shot that load today

W-W 760 44.5grs with Sierra Blitzking produced 3,925 average. Tight groups . I wonder what that would do to a coyote?

velocity is pretty good

My first batch was over 4000, I have also used varget to get 4225 but ohhhh the primer pockets were done.....

I might try H414 but i am pretty happy with ww760.....

Coyotes????Welll, lets say it works VERY well..... I shot one in the boiler room at 450yrds, when i picked it up ituthere was some heavy gurgling from inside.....Jello. Works great.
U MIGHT WAS TO try the 55gr nosler... They have a better BC.

cream of wheat ... 25 yrs later.

Gentlemen...with over 25 years + reloading experience I always have and still still fireform using "cream-of-wheat" in all calibres from 17 REM to 300 WIN Mag...7MMSTW...308 , 260, 243 Ackley,22-250Ackley...20PPC , 20BR
have never had a stitch of problem light bulb

Bob @ Sinclair International order line uses cream of wheat and is a huge fan of this process.

I fireform ALL new brass using cream of wheat.
I've never had a misfire or usafe occurance using 700X powder and poly fibre capping (NOT WAX - THATS A MESSY-WRONG TECHNIQUE )
All my fireformed loads are developed with crisp shoulders.

Hydro dies are surely okay - but they're a custom item that costs money and time to obtain and limited to one particular calibre/rifle.
Its just another choice with same end-result.

Different strokes for different folks
Good shooting

Can't we just get along??????

OK today shooting my Cooper Classic with a after market fast twist (8")5R BBL. Using two powders load combos IMR 4064 and WW-760 55gr Nosler W-W Black tipped bullets and Sierra 55gr Blitzking bullets .Both max charges. My rifle has a sporter stock with sporter weight BBL haven't been able to get super great accuracy. 3/4MOA and a few 1/2 MOAs with a few flyers but I figure for hunting coyotes they'll work.
