22 Grendel, slightly bigger brother to the 22 ARC

I built this in late 2022 with a Howa mini & factory 223 1-8 19" barrel, been sitting in the safe for a couple of years since then, I had an AR upper in 22 Grendel back in the good old days

It's had 147 rounds through it now, started with the 77 TMK & it shot incredibly well at around 3050 fps with 2208

With the recent advent of the slightly smaller 22 ARC and load data availible, I dug it out & loaded up some 68 HP, 77 TMK 80 & 88 ELDM for fun with a ball powder

It still shoots very well for a factory barrel even with the noticeable increase in velocity from the different powder, with the 77TMK, & 80, 88ELDM easily capable of sub 1/2 moa at 100

I guess less than a 223, more than a 22-250, way more than a 22CM, 22-243 etc

Is it a straight resize of the Grendel case Greg?

Yes 6.5 Grendel necked down to 22, I also have the 6.5 necked up to 30 which is an awesome cartridge

Tried some Hammer projectiles in it this morning, the 69 Absolute Hammers first

Then the 68 Hammer Hunter Tipped

Pretty good for a guessed length & powder charge, pretty normal for Hammer projectiles to be fair :)

Cripes they would sting.
Ive just loaded some 68 Hammer Tipped and 62 Makers to try in my Creedmoor. Up around 3.6K fps

Nice, they will sting even more :)

Why did I look at this thread.....

could one of these be built on a rifle that is currently a 243?

The bolt face & feeding from the magazine could be problematic, the 22 x 47 Lapua or bigger 22 Creedmoor would probably be a better option
