22-250 Powder

[redneck2]

I switched from H380 to IMR8208xbr. That leaves me with a couple of 8 lbers to do something with.

I always tend to think of H-380 as a 22-250 only powder. If you look at the website, it works in about anything Varget or BLC2 uses. .308, .300 or .250 Savage .243. I suspect it's a little slow for .223.

Anyway, I started with H-380 and 50 grain Nosler BT's. First group was one hole. It should work as well or better with 55's. I'd use it because I got 4# at a close-out for $10/#

Yep, 380 is great in my .243.

Well, for the most part it seems the original powder for the 22-250 just might still be the best. Unfortunately I don't have any H380 on hand but I do have H-4895, IMR-4895, IMR-4064, Varget, H-4350 and a little W760 on hand. I think I'll start with IMR-4064 while looking for H380 and maybe I can even find some CFE-223. I'm sure the 22-250 leaves a good amount of copper fouling behind at the speeds the bullet is traveling.

Thank you all very much for all the helpful suggestions! I learned a lot about 22-250 powders I didn't previously know.

After a dismal failure with Varget and my choice of the 52gr A-Max out of my Remington barreled Mauser, I tried some IMR3031 that I had, and everything went under an inch, with some 5 shot groups under a 1/2 inch. I ended up at 33.3gr of IMR3031 under the 52gr A-Max.

Back in the day, (70's) 37gr of IMR4320 was The Load under Remington's 55gr Powr-Lokt bullet, and I never saw a M700 or M788 that wouldn't group well with that load. That's now over the recommended max with a 55gr bullet, but it wasn't back then.

If I had some CFE223 or IMR8208, I might like to try them for potential.

We're getting fairly equal results from IMR4064 and IMR4895

Imr 4895 with berger 52 gr in a savage is good out to 300 yd, dont know beyond that

Reloader 15 & Varget both shoot very nice groups in my 22-250 with 55 grain Berger bullets. I have just loaded up a ladder with 8028XBR, but I have not gotten to the range to test them yet.

When I was trying to find a cheap load to poke holes in coyotes without damaging the fur I found that 33gr of 4064 with the hornady 55gr fmj-bt w/c seated to the lands gave me consistent 3 shot cloverleaf groups @125 out of my rem 700 sps 22-250 and that load shoots equally well out of my friends tikka (different seating depth of course)

4064 is tops in my book

Richard Lee suggested in "Modern Reloading" that in general one should strive to [fill the case as full as possible with the fastest powder that will give safe pressure]. I've always remembered this advice, for some reason. Obviously there are limits, and with a 22-250 you're dealing with a substantial sized case for the caliber.
