Best Powders for loading 223

Page 1 of 3Next

I, like others here have only loaded pistol rounds but am ready to move to rifle rounds.  I have 223 dies on order and wanted to ask if others can provide feedback to the best powders for use on the 550B for 223/5.56. 

Not asking for specific load data only the powders that others here have successfully used.  I have read where some powders do not drop as accurately as others and I wanted to ask for powder recommendations I should work with to insure the most accurate, consistant drop weights time and time again.

Thanks in Advance for your responses

   Don't know if this will help but I just finish firing off my first reloads of .223 at the range this week using the Winchester 748. That was the only thing we had locally for rifle loads for AR's. 1st time using win 748 but it measures very accurate and the drops were very consistant on my 550B....a very good ball powder with no droppings during loads...if they stocked it in 8 lds I would pick some more up in a minute. I also did the $27.50 hazmat trip online to pick up some Hodgdon 322...Alliant AR Comp and Power Pro 1200r after lot of research and forum work, the later 2 in 1 lbs containers.
   Alot of work but alot of fun so far and since my friends raised me right, QD's and inspections are up 200% like Black Hills Ammo company. I will close with this...doing the math for pistol rounds compared to rifle...DAT DAMN POWDER AINT' GOING AS FAR....SMILE.......So enjoy and be safe on the bench to the range.

Hodgdon H335, BL-C2, CFE 223, Winchester 748 and Military pulled down powder W844 are all good. Each powder meters well and delivers good accuracy.

 

I use BL-C(2), meters great and does everything I want it to do.

Impossible to get H322. I just loaded a 100 rnds with IMR4064 I'm not crazy about the way it loads it's cylindrical. We'll see how it fires.

Varget has been the best stuff I have seen used for .223, of course these days, you may have to select another flavor that you can purchase.

 

Winchester 748 and BLc2 are both great and deliver good accuracy.

Well, I don’t actually know a lot about it, but it really reminds me of a tale my professor one time shared with us: apparently, this thirteenth century English alchemist tried (in vain) to make gold from lead. He examined those ingredients so deeply, he evolved into an expert on both, and became rich as an official guide to the queen. Data was hard to come by in those days, far apart from nowadays with computer availability, and committed drivers etc. back then, once you realised something good, you could keep on counseling for a lifetime. But I digress. What I’m saying is that every now and then you come upon riches by simply attempting (and staying devoted to) something else, and thats just what happened to me once I accidentally got here. I was actually on the search for some technological records about driver updates when I began scouring the web, and got carried away…. Keep up the excellent work, and thanks for the article.
