New Build: 22 ARC AR15 Platform (gas)

[simo]

I shoot targets, no game. Targets in yards: 100, 150, 200, 250, 300, 350, 400, 600
I've ordered parts for a new build and loading.
22 ARC barrel from X-Caliber, 24" Bull 1:10 twist rate
RCBS full length sizing die and seating combo
Hornady V-Max 40gr and 50gr
Powder Hodgdon BLC2
Loading data that I can find only goes as light as 53-55gr in a 7:1 twist, so some experimentation is on the table
I also have H335 and X-Terminator on hand
I am no-longer new to reloading, but I do not have the experience of many of the veteran reloaders on this forum
So, any tips or suggestions are welcome.
I will post results when the rifle is assembled and answer any questions along the way.
Thanks!

If going to 600, I personally would ditch the 1:10 and the 40-50 grain bullets. I'd go 1:9 and 69-75 grain bullets. Easy Peasy. Brian.

Thanks for the reply! The barrel is already ordered, it is a 6 groove 10:1 twist, which according to Berger's twist rate calculator, it will stabilize up to 55 gr decent.
What powder are you using? Muzzle velocity? MOA at 600?

I have a White Oaks Armament 5.56/223 24" Bull, 12:1 twist that I am currently shooting at 600 yards, 12 MOA, zeroed at 100, using H335 and X-Terminator max loads with 40gr V-Max

You could give the 60 gr tipped match king or 69 gr hp mk. They can run out of 10 twist barrels. Better bullets then the varmint bullets.

Thanks! I'll look them up on HRDC.

I’m surprised you’re running such light bullets in 22 arc for shooting steel
My 22 arc is 1-7 and I primarily shoot 80’s at 2900

22ARC at 805 yards.

Looking at the Sierra Load Data for 22 ARC with the options I have for bullet weight, it looks like TAC is going to be a better option than BLC2.

Impressive! What MOA at 800?

It’s a cheap green mountain barrel blank I chambered but hitting steel out to 1000 isn’t difficult with it.

Hard to beat the 69SMK.

Cool. I opted for the 10:1 twist because what I've read is that the slower the twist, the lighter the projectile, the flatter the travel and more distance. Lighter bullets are less expensive, and I shoot a lot, and it's just my preference. I have some 60gr Sierra Match Kings on my wishlist, I will give them a try after my 50gr V-Max. I shoot on my property, and 600 will be the max for me.

After about 500 yards the heavies can shoot flatter with less wind than the light bullets so it depends on what range you shoot, I rarely shoot less than 500 yards hence my choice.
