Best powder for AR15 w/16 inch barrel?
Hi all! I will be finishing up on a custom upper very soon and will be doing all my own reloading. What powders are you folks finding works best with a 16-inch barrel? I'm thinking a faster burning powder would work best?
Best to buy a manual and follow it precisely as to there specifications.
Google IMR for a less comprehensive free version.

There are so many different powders and you will get so many different answers. It really is a personal preference. I prefer TAC, lots of people use varget, h335, h322 but your asking a very vague question. What weight projo are you planning on using?

That would be H335 instead of H355 wouldn't it? I use Ramshot TAC as well as Accurate Arms 2230 with 55 gr. bullets and H335 with 62 gr. SS109 bullet pulls.

Every barrel is different, there are so many powders. The powders that work for an Ar are not that far apart as far as burn rate. There are faster and slower, but your barrel is going to have little to do with the powder you choose. Faster for lighter bullets, and slower for heavier. That is not even set in stone a member markm has a killer load using h322 for 77 matchkings. Most Will say h322 is to fast for the weight, but his results show different.
Your going to have to do the leg work for your gun, but barrel length is the least important part of the equation. Once you get to shorter barrels it gets more important, because you are trying to squeeze more speed from a short barrel. With a 16" barrel choose powder for the bullet your loading.

Yes thank you I edited the original post to avoid any confusion.

I was thinking the same exact thing the other day. Why would I spend $30+ for a manual when I could call the manufacturer (or just find it online) for the exact bullet and powder combo I want to use.

Not crazy but loading manuals are essential. You can call a manufacturer, but you have to write it down. You might have a dislexic moment and mess up the numbers. What if you want to load, and there closed. If you call and ask for a specific powder bullet combo that's not to bad, but what if you want data for multiple powders. Or you would like to know how all the powders tested compare. Most companies are good to us, and Will spend time with us giving us all the info we ask for. If everyone stops buying books, and starts to bug the companies for all the data in the book they will get tired of it possibly causing us all to loose a great resource. Try to get load data from federal. They are not helpful.

Not saying you guys are in that category, but i see a lot of questions that could be answered if they owned a full book. Blacknight & ironman8 the only questions or posts i have seen from both of you either lead to good discussion or are good answers.
If you do not want to buy manuals you can get them for free from multiple companies. Books are not obsolete new loader are getting lazy and want to be spoon fed everything. I feel it is very important for loader to have manuals i have given some away, and bought a few for people.
Ironman8 the 62 tbbc was not released as a component. That is why there is no data for it. When speer was making the tbbc they only had data for the 55. Now that they are a federal product we Will never get any data.
Another thing is a lot of loader seem feel s is going to htf, and if you fit into that pitch what do you do when it happens and you can't call a company or.access the internet.

All the actual load data you will need for loading .223 can be found online, free of charge, directly from the manufacturer of the powder. You don't need a load manual for that.
http://www.castpics.net/LoadData/default.html (there are some older full manuals here in pdf)
Or if you want something more recent but don't want to pay you can check your local library. A book will give you more insight on the reloading process but all that information can be found online these days too.
Each gun is an individual so no one can tell you which powder will be best for your rifle. If you are shooting iron sights, a 4moa red dot or surplus FMJBT bullets, you probably won't be able to see an accuracy difference between several different powders. Look at this chart and find Hodgdon H332 and CFE223, http://www.hodgdon.com/burn-rate.html I recommend staying between those two powder on the burn chart. Going faster and you may start having cycling issues though some people use 4198 just fine (Works fine in my Mini 14). I generally use Ramshot X myself. WC844 is a good budget powder if you can actually find it right now, uses H335 load data but start at 85% instead of 90% for load development.
