I am reloading for the most part for a 5.56 AR. I have the equipment and the manuals (read them twice) and with the price of powder I'd like to know which one is a good place to start at?
IMR's 8208 XBR is a rifle powder based on an old favorite among the benchrest community, real sticklers for accuracy, with a distinct difference. There is virtually no change in velocity with modest or extreme change in temperatures. The ballistics group at IMR has tested this powder from -40 to +165 degrees Fahrenheit with virtually no performance variation.
In the field Mr. Jim Carmichael tested the new powder in a practical way; he won the 2009 Heavy Varmint Aggregate at the International Benchrest Shooters National Championship.
Pleasant weather, cold or hot IMR 8208 fills the bill with championship performance in many cartridges from .223 Remington to .458 Winchester. Whatever you are aiming at it's no match for new IMR 8208 XBR.
My mistake like I said I'm new to it. I shoot a lot of military ammo 5.45 7.62x54 and so on and alway hear about the corrosive aspect to it just figured it was the powder.
There is corrosive ammo. But it has always been the primer compound that was corrosive, never the powder.
There are at least a dozen powders suitable for 5.56/223. I'm sure there will be someone that will tout Varget. There are lots of powders besides Varget.
What bullet weight and barrel twist are you loading for?
Are you going to be using your reloads to basically blast steel plates? Accuracy by volume type of thing, or are you wanting to get sub MOA, sub .5 MOA groups with it?
If just going for bulk, I'd find a ball powder that you don't have to use a lot of (5.56 though seems like everything runs 26-31gr) and go for it. Some powder is still a pain to find, pickings might not be optimal.
If going for dead nuts 1 hole groups by benching it, then more than likely you're going to have to try a wide array of powders unless you luck out. I tried 7 different powders through my AR-10 before I found one that shot tight groups (BLC-2, Varget shot like hell).
One other consideration is how are you metering the powder to load? I liked Varget until I bought my Dillon, stick powder was a bit inconsistent. H335 works well for me but I am not shooting match either.
The .308 I'll soon be reloading for will be more of a bench rest. But the AR is more for bulk. Been running 3 gun drills and tactical shooting classes and I'm just burning up the brass right now that's why I'm getting into to reloading.
