Ruger 22ARC, best loads

[Castle Rock]

I’m going to help a mate try to get some good long range loads working.
We are particularly interested in 69, 80 and 88s with Varget and 4350 if you have any info to share it would be greatly appreciated thanks

It's not the ARC, but I'm playing with a new bolt build in 224 Valkyrie. Looking up case capacity, they are very close. I would start with Varget and an 80gr match bullet. I am using shooters world precision, so it's pretty close.

I'd start breaking in the barrel with a 25-26gr charge and play with your seating depth. I found I had to get real close before the 80gr eld tightened up. Barrels still speeding up, but I'll be comfortable at 2800fps shooting well under an inch.

It was an Adirondack in .300 AAC Blackout. So .223 bolt face.

Yes, one of my favorites. Pencil barrel, .482" at the muzzle, and it shoots exceptionally well.

It took me a while to find a .223 bolt face too. I was going to go with .223 AI, then the ARC was introduced, so I decided to go with that.

Another option is a .308 bolt face Kimber rebarrelled to 22 GT.

My rifle likes 26.8 gns of h4895 80.5 bergers 2975 out of a 20’ barrel. Varget was quite a bit slower.

I've got a 22 creed Kimber like it alot. Did think I might do a GT next time. But was hoping to make a 223 twin as a training rifle .
