I realize that different rifles like different powders. But among you reloaders that have used both powders for .223, which do you find is more accurate for:

1.) 55 grain FMJBT
2.) 68 grain HPBT

-Separate question- I f you were going to choose ONE powder for both of these bullets, which would it be?

1.) 55 grain FMJBT AA-2230, what my 2 AR's liked better.
2.) 68 grain HPBT Never tried them with this bullet weight, always used Varget.

-Separate question- I f you were going to choose ONE powder for both of these bullets, which would it be? Tac, first choice, BLC2 second. Both of your picks burn a little fast for the 68 gr bullet weight.

Varget would be a good choice for both.

For me, it's BLC2 for 55 and 62 gr bullets, Varget for 68 gr Hornaday BTHP.

H335 with a Mag Primer for year round use.

I use H335 for both. I see know reason to change at this point in time.

W 748
This is one of the most versitle and easy to meter powders for the 223 !
Most of my velocity , accuracy loads and variety of bullet weights loads
are with 748
Ex 52gr Sierra mk,55 fmj,62 fmj, 68 and 69 match and even 75 gr Hornady
match ...However if you live in area where temps get really HOT like over 100 degrees
It may be neccessary to reduce your charge wieghts.
TAC is also an excellent powder for heavy weights like 75,77 and 80 bullets
and will also work great in the lighter bullets.Since I live in PA and not the
Arizona desert my vote would be W 748
H335 is just ok for me but I can't seem to get the velocity and accuracy as
W 748

Do you have the powders already, or trying to figure out what to buy?

If it has to be one or the other, I would use which ever worked best with the 68gr loads since they are most likely to run into pressure issues and most likely to be the loads to provide best accuracy.

If it were just me, I'd be reaching into storage for some TAC.

Looks like TAC is the KoolAid flavor of the day, I wonder if they can make it in blue?

Here's another separate question regarding the 68 gr HPBT Match bullets. I've read the other thread on crimping and just want to know what you actually do. I understand the different schools of thought on this matter. Do you guys crimp this bullet even though it has no cannelure for your AR's?

No I don't crimp it and have had no issues as long as adequate neck tension is maintained.

How do you ensure that adequate neck tension is maintained?

Just take a loaded round and push the tip into a scrap piece of 2x4, if the bullet goes into the case then there's not enough neck tension. Go by feel, if you push hard enough on any case, crimped or not, you can push the bullet into the case.

Not much you can do to increase neck tension other than using a smaller expander ball

ONE of those two?

H335 hands down.

I use H335 for my 55, 62, and 69 grain loads with mag. primers. I get better groupings.

I bought AA2230 last year. Loaded 20 rounds of 55 grainers and showed a tad higher pressure due to primers flattening more than my H335 loads.

I started out loading H335 for my 16" AR with 1 in 9" twist. I got pretty good groups 1.5" with 25.0 grains of powder. However, I just tried some AA2230, and got even better groups with 23,5gr 1" as well as 25.0 grains (1.2"). Point is, try several powders and see what your rifle likes. I think for 55gr bullets H335 or 2230 are great powders to start with. Hope this helps.

I don't crimp my 68 gr match loads.
