2400 for cast 22-250?

[David R]

I am looking for a load for my 22-250. I am presently using 18 grains of SR4759, but it doesn't meter for beans. Does anyone have a suggestion?

PM if you don't want to post it. I can't find anything in my manuals.

I would like to chrono these loads, then load the 2400 to match the velocity.

Thanks A bunch

Start with 14 grains 2400 for approx 2400 fps. ... felix

AA 5744 is an excellent cast bullet powder very close to the burning rate of SR 4759, but it meters a whole lot better. Put IMR 4227 right in that same category.

Nothing wrong with 2400 though in my book it is my powder of choice so far for cast loads. Jim

David,

Try 28 - 30 grains of RL15 with a magnum pistol primer. That is 34,000 psi and will work with ACWW. Velocity runs 2750 - 3000 fps from a 24" tube.

[David R]

Thanks Felix, that is what I was looking for.

Scrounger, I just read an article in Handloader about 5744, I will try it. I like the 4759, but I found I have to weigh every charge. Between that and weighing boolits on a beam scale, it cuts into my limited shootin time. Wish I had a digital scale.

Yeah, that 4759 is a caution in a powder measure. I kept some short-term records a few months back and found that on average, one charge in fifteen would not drop completely from my RCBS Uniflow.

That's far too often for my peace of mind, so I went to check-weighing every single charge. Once I work my way through the 4759 on hand, I'll be using other powders such as the suggested 5744, 2400 and 4227, all of which I've used fairly extensively already. Trouble like that, I don't need.

A gent over on accuratereloading.com. with the handle of Seafire/B17G (I think he likes old warbirds!) has been running a very extensive test series with Blue Dot in a wide variety of calibers. I tried one experimental .32 Special load (12.0 grains Blue Dot/RCBS 32-170) in my Marlin and it looks very interesting indeed....good accuracy results! Dunno about the speed, as my MkIV chrono boom for Der Schuetzenwagen is still under construction.

Curmudgeon was smacking the daylights out of a 4"x6" gong at 100 yards with this .32 load...offhand! Made me a tad jealous, it being my rifle and all.

I have never used 4759,but I also have not found any powder a Belding&Mull powder does not accurately meter. Saying that has nothing to do with my having a B&M Measure for sale.

I just put some old handloaders on ebay yesterday and re-read them before they sell. .22-.250 rang a bell. 1979 tests to develop a light load for Chucks with low recoil and great accuracy should hold for cast as well. He worked up loads with magnum primers as previously recomended and 60gr hollow points and twenty one grains of IMR -4198 these hit 1/2 in higher than did his full hunting loads of 32.5gr IMR 3031. He setteled on 22.5 gr of 4198 got very good accuracy & light recoil & noise, his goal. Cast should perform as well I would think? Others agree? JB

[David R]

JB,

I tried 4198, approx 21 grains, it didn't group for beans. The 18 grains of 4759 works great, but I HAVE to weigh each charge, they vary by .6 grains from my redding measure.

I tried 14 grains of 2400 tonight, just to see if it was close to the velocity of my pet load. My "chrony" that is more than 10 years old is due to retire. It was reading from 1100 fps to 2690. all in a string of 5 shots. My loads are much better than that. SO I got out my swinger. The 4759 loads were much faster than the 2400 loads. I can go up and be careful. All I needed was a starting point. I will keep at it.

Right now I can get just barely over an inch at 100 yards with the 4759. I hope to find another powder that I can just throw instead of weigh with the same groups.

umm well, I went to the first silhoute match tonight. I took my 22-250 that will shoot lead just over an inch at 100. I shot my first five chickens at 25 yards. Piece of cake. THEN they went out to stand them up again and My boolits had penatrated 1/2 way through the 1/2" cold rolled steel. I put the gun away. They are 57 grains and should be going just under 2400 fps. acording to the book. I really didn't expect this, but its back to the drawing board. I need about 1/2 that velocity.

Most clubs have velocity limits to limit target damage. The good news is that your gun/bullet will most likely shoot even better at a lower velocity. Try to get a load at about 1500-1600 FPS. If you go down to 1200, your load will be trans-sonic and probably much less accurate at 50 or 100 yards. About 1600 should keep you above the sound barrier all the way to 100 yards. If that was a .223, I could make some pwder guesses, but I have no experience in that arena.

Scrounger, I may be shooting a 222 in a few weeks. I have one and I think the twist is 1 turn in 12. Its a Savage 24V. 222 over 20 ga. It has a reciever sight so I can shoot in the non scoped class and maybe still hit some thing. I have lots of 22 cal boolits weighed, sized, gas checked and lubed. I will shoot for 1600 and see what happens.
