Anybody tried or running CFE-223 in a 22-250 with 40-50 grain bullets and getting good accuracy at or near max loads?
Looks to give some very impressive velocities but I am unsure how accuracy would hold up at the higher pressures it seems to operate at.

I have used it in my Cooper 22/250 - 39.0 gr/50 gr Nosler BT, it gives very good accuracy in my rifle - 5 shot one-half inch groups at 100 yds, it chronographed in line with the loading manual velocities. I am impressed with it so far.

I use it at 38.5 gr with 50 gr Bts. Very good accuracy and 3650 fps out of a 22" Ruger.

I've had outstanding luck with it in the .22-250 with 40-grain bullets at 4300+ fps. In fact, overall I've had better luck with CFE223 in the .22-250 than the .223.

With 42.0 grains of CFE223 both the 40-grain Nosler Ballistic Tip and Cutting Edge Raptor shoot very accurately, and to the same place. My wife and I use the Raptor on larger varmints and deer-sized game, and the Ballistic Tip on small varmints.

Have you tested to see just how flat that BT shoots at 4300+ fps out to say 500 with a 200-250 yard zero?

It shoots very flat to about 300, but beyond that it loses steam. With a 250 yard zero it's about like this, using a scope 1.8" above the bore:

100 +1
200 +1
300 -2
400 -9
500 -22

Wind drift also starts to increase beyond 300, where the velocity has dropped below 3000 fps. But out to 300 its pretty good!

I bet would be great for my coyote hunting where there is minimal time to range dogs, center hold to 300-325 then just on top of fur at 350 to a little daylight to 400.

Yeah, they would. I've also used them in the .220 Swift at similar velocities.

And they make rodents pop!

My 22-250 seems to have a bit of a tight barrel and my top loads with the 40 gr. BT are lower than JB's and not quite reaching his velocities. However, at the upper end with both the 40 gr and 50 B/Tips, it's usually around 0.5" for five shots, occasionally going down to about 1/4" to 1/3".


That's after not cleaning for about 200 rounds.

Is it just me? It seems like CFE223 keeps copper out of your barrel by leaving so much carbon in there the copper won't stick. I have tried it in, while not 22-250, a couple of different cartridges and always find what I think to be more dirty than normal barrels.
I know, stay with the topic. I'm half way on it at least.
I have always used 41 grains H380 behind a 50 grain NBT (well almost always) and had great success on the PD towns. After thousands of rounds of that load downrange I think the NBT 50 at 3980 FPS puts them dawgs in great peril well past the 500 yard mark.

shoots, for me h380 was really a dirty powder!!

3980 with H380 is cookin. Long barrel?

That was a few years back when I chrono'd it. Weatherby SVM with 26" Criterion 12 twist. Has the traditional Weatherby long throat. The rifle has been a "go-to" for me since 2001. For several years it went along twice a year. A couple of years (had that cancer thing's azz to kick) it didn't go. Then last year in WY it got ignored (only shot about 350 rounds) for the 223 AR with a suppressor. My guess is 3500 rounds thru it now and still a killer. A late friend hung the moniker "Death Ray" on her a about seven years ago.

Speaking of making speed, I just saw an ad for Hornady Superformance in 22-250 advertised at over 4400 FPS. That is smokin'!

Bet that is for the 35 grain unleaded.

Yup

Anybody tried this powder with the 55 weight bullets and had much luck?
