Re: Hodgdon CFE 223 powder
CFE 223 has no temperature stability. A chrome lined barrel does not need copper fouling eliminator in the first place. H4895 is the best all-around .223 powder. Go a range faster or slower depending on bullet weight, but stick with temp stable powders, Benchmark thru Varget for .223 Rem., depending on bullet weight.
If you shoot prairie dogs all day long at a narrow temperature range, then CFE .223 may be your powder. Even then, there are several others that work just as well and will work much better at temperature extremes. Fourth of July isn't that far away, and aalso ny CFE .223 you have laying around might make some good fireworks.
Remember when you were a kid and putting a primer in a cigar was a fun prank? CFE 223 is about as useful as a primer for similar purposes like spiking the fireworks. As a practical rifle powder, I got over it a long time ago.
The guys I know who like CFE 223 are reloading guys who brag about its consistent metering. Every throw is "right on the money" according to them. What the hell is consistent metering worth when the powder itself is another ball powder with known temp stabilitry issues??? Buy an ultrasonic cleaner and wean yourself from clean burning ball powder that does not cut it in performance next to the best stick powders, and trickle up your charges on an accurate beam balance scale. Just say no to temp sensitive ball powder.
CFE 223 has one very good quality in that anybody who swears by it is nobody you want to take reloading advice from. It gets a very high rating in the "dumbass advice to avoid" category, and for that it has some usefulness, from personal experience.
