I knew you were joking. I had to go back and re-read his post to see that he actually didn't mention the cartridge when I read your first post.

I have found 69 grain Sierra Match Kings (the HP, non-tipped variety) and Varget powder to make loads that shoot very well in a variety of AR's, although I don't know if I've put them through a 1:9 twist. I think a 1:9 should be able to digest them just fine. That combo doesn't seem to be very sensitive to small variances in powder weight, nor to seating depth.

I hear another shooter - a far better rifle shooter than me - say that if a .223/5.56 rifle won't shoot a SMK/Varget combo, then that rifle just won't shoot.

A Three Hundred Blackout load would work with a nine twist as well, but I haven't even taken the plastic wrap off the die box yet.

Of course, one should be sure the barrel is of thirty caliber, too!

The one factory load I buy is for my Blackout. I need cases. And they shoot so well, verily the only Remington ammunition I've had do so.

I use Benchmark, with a 55gr. Hornady SP, that I buy in 6000 qty.

24.0gr Benchmark
62gr Nosler Varmageddon HP
LC Brass
CCI 400 SRP
2.180" OAL
20" White Oak Armament Varmint Barrel

This my favorite load for both my ars

LC Brass
CCI 41 primer
22.5 gr Benchmark
55 gr V-MAX
C.O.L. 2.250
No crimp

Another H335user here. It pretty cut my groups in half from factory Federal ammo I used as the baseline with the 55 grain bullets.

Wow, a lot of you loading with H335.

55gr Speer SP (#1047)
25.4gr AA2230
CCI #41
2.24" oal
I usually sort the brass although there's little difference in accuracy between the brands I use.

going to try some AR Comp and 62gr BTHP

Are there any Alliant loads worth noting??

Unfortunately, in the Benchmark/H335/TAC/H4895/Varget/BL-(C)2/CFE .223 powder burn rate, Alliant's offerings are Reloder 12 and 15.

I think AR Comp is in this range?

LC brass
25.0 grains of WC846
55 gr FMJBT bullet
Winchester small rifle primer

25.8 gr. BL-C(2), your choice of 55 gr. FMJ, ( I usually buy Hornady bulk), CCI 400, range brass, mostly LC, 2.23"OAL. Topped with 55 V-Max, it is my son's hunting load. Topped with Nosler 55 gr. Varmint, it's mine.

Power Pro 2000 is an option. I've used it for 308 win but never for AR loads

And Power Pro Varmint. I loaded up a bottle of it some time ago, when I couldn't get BL-C(2); Good loads, but I went back to BL-C(2) after, the load I listed above works too good to switch.

If a mag length 50vmax over 27.3grn Varget doesn’t shoot well in your rifle, there’s probably something wrong with your rifle.

I have used 8308, H335, BLC(2) and TAC.
My two rifles both seem to like BlC(2) and TAC, close call between the two but I give TAC the nod.
All meter well when throwing charges.

done yet !!!!

I said the same thing. I modded the stock one before replacing it. But it still was a huge step up.

LC Brass
25.0 grains of WC846

1:9” twist down to 11.5” has been fine for me with 69smk’s. 77smk’s are sometimes compromised in short 1:9” barrels, but that’s why we created the 69’s.

I found my 1in 7 barrels shoot 62gr better than 55 and my 1in 12 barrel shoots 55 and 52gr better. I've not tried different powders just H335 and have only tried the 3 bullets weights listed abd am happy with my results so far.
