The 22 creedmoor thread

[swavescatter]

I ran N555 with 77tmk in my first 22cm 3-4 years ago. It was a 22in 8tw. Chamber was throated long to keep the bullet above neck shoulder junction. I was running lapua brass. I was able to find pressure(hot conditions) with somewhere around 44.3gr if I recall. Was using a 12" drop tube and vibrating cases to get room to seat without crunch. This was running mid 3400mv. I eventually dropped it down to mid 3300s for an app season load.

I'm currently running 42.2gr N555 in the new 18in barrel with 88s at 3040mv. You can get up to 44gr in alpha brass.

How is the accuracy (compared to other powders)?

N555 shoots great in the 22cm! My load with 88s will routinely shoot sub half minute for 5 rds at 300-400y on paper.
