The 22 creedmoor thread

Same gun, same bullet, same load, 200 rounds apart. Scrubbed it clean, for science. Interested to see how things shake out on the next range trip.

Also to note on my post above. I’ve chronod a high percentage of the “good” lot and haven’t really seen much more than high 30s to low 40s for ES. It averages right at 1 MOA consistently.

This new lot averages closer to 1.5-2 MOA consistently and I regularly see close to 100 ES on 10, 20, 30, 40, and 50 shot strings while practicing.

Just some minimal “data” to throw out there.

Wondering if 22 creed and an 8 twist barrel is more susceptible to accuracy degradation with larger velocity discrepancies? The 77 TMKs always shot 1 MOA as well, with an average of 30-40 ES. Does anyone think that 80 grain at 22CM velocity is right at the threshold for an 8 twist 19” barrel?

Crossed 1,000 rounds on the barrel today and it’s still 1 MOA with the “good” load so it’s not “dirty throat” or “dirty barrel” causing any issues with the other load I wouldn’t think.

Probably chasing my tail over nothing?

I think it’s just factory ammo - you might get lucky and your rifles loves it or sometimes it doesn’t.

That’s almost exactly what mine looks like. How many rounds? I’ve lost track on mine but approximately 600. It was a 1” for 10 shots now closer to 2”. Curious if cleaning helps yours.

The first one is literally the first group through this barrel lol. Second is the most recent group, not quite 200, 191 I think. Should be able to shoot in the next couple days some time
