I know some of you guys may not travel into the variants forum and probably less of you are following the 25-223 thread.
went out and did some load work with hornadys 75gr HP. Figure i would share and see what you guys think of the results.


Bullet: Hornady 75gr HP
Powder: H335
primer: CCI41
OAL: 2.250

All targets were shot at 127 yards off bipod and rear bag.
Started at 26gr and worked up to 27.5gr in .5gr steps.

26gr

velocity:
HI-2688
LO-2629
AVG-2662
SD-21
ES-59


26.5gr

velocity:
HI-2783
LO-2760
AVG-2766
SD-9
ES-23


27gr

velocity:
HI-2849
LO-2807
AVG-2836
SD-16
ES-42


27.5gr- flattened primers and ejector swipes

velocity:
HI-2886
LO-2818
AVG-2853
SD-29
ES-68


overall they shoot great ill be loading about 15 rnds at 26.5, 27, and 27.3, then reshoot and reevaluate them.

From what i am reading from all the data its looking like the sweet spot will be between 26.5and 27gr.

What do you guys think?

I think I'd just settle on 27 and let it go at that.

27.0 grains looks pretty good.

I have been following the 25-223 thread in AR Variants.

Nice to see Hornady is now making dies.

Seems like the front runners in this caliber really paid their dues when it came to die sets.

You aint kidding i think i have $300 in dies that i bought to get something to work. Of course the easiest solution was the damn answer

what are good dies?
i have dillon dies i use, should i reconsider buying a second set for precision 556?
my goal is to replicate/exceed TAP accuracy and ballistics

any good set of dies will be fine for standard calibers, i am not loading a "standard" caliber i am messing with a wildcat, IE: a non standardized chambering.

For 223 i would say in my newly acquired experience you cannot go wrong with reading dies, and if you plan on trying a few different bullets get the competition seater die it will make life very easy.

You stumbled into a 25-223 thread.

A wildcat round.

Maybe look into getting a micrometer seating die. They work wonders for precision loads. Also try going without a crimp and just using the neck tension of the case. It drove my groups down to under. 75 just by not crimping. Don't change anything else that way your only fighting one variable at a time.
