Thread: My 22 Creedmoor is ready...

Blasphemous!

Looks like you're coming full circle with the statistics. Some rifles are precise enough that its not really worth shooting 10shots group each time you zero a rifle.
I dropped and fell on my rifle a few times while hunting the Ruahines this last week. I was sure it would be out. 3 shots of my main load later and two of the bush load (which crono'd 80fps slower?) and i knew it was still dead on (1 click left to negate spindrift)

Hah. You should see my shooting on a bad day.

Now that your sure to bin this barrel @Tahr, i'll buy it of you for a song
I might try get a 22 CM barrel with the excuse that it's for my daughters

If you want some superperformance to try in it I've got some you're welcome to have

2209 is really a bit on the quick side for optimal performance. 2213 would be a good choice, I’m using IMR7828ssc in mine. Something in the region of 42.3gr with 88’s

I'm using rl22 atm with 88s
Not super quick at 2864fps 16 inch tube but doing the busy

On the topic of hot calibres eg Creedmoor necked down here is an experience of mine.

About 40 years ago a gunsmith mate made up this wildcat.
I cannot remember all the detail eg barrel source (maybe ex machine gun, I don't know).
He didn't have a chronograph (they were very rare back then) so no idea of the velocities.
No idea of powder (there was a lot of strange unidentified ex military stuff still around then) or how much.
Accuracy was abysmal with some projectiles maybe not making it to the target.

I think he got around 200 rounds before the barrel was toast and became a tomato stake. Maybe overbore?
