22 creedmoor bullet question

[DLT]

Will the 60gr vmax hold together in a 1:8 twist 22 creedmoor 24” long ? I’m itching to shoot it tomorrow I just got the rifle put together but don’t have any of the 62 eld vt to try just yet Thanks guys

It's not what bullet. Any bullet run slow enough will hold together.
How fast do you want to push it?
Use this calculator, Speed in FPS X 720 = # then divide by your barrel twist
gives you your RPM's
Most will say anything above 305,000 is pushing it. 315,000 is tops for long periods.
Keep your barrel clean and don't run long strings to increase the fire cracking.
Some bullets will hold up better than others.

Well i did the math. 3,500 fps is not good for em in a 8 twist if that’s true

Yes, you should have no problems.
A couple years ago, I built a 26" 22CM on an 8 twist Wilson barrel to shoot 75elds(3400fps). I also built a 24" 22-250ai on a 12 twist Douglas to shoot 53's(4000fps).
After returning from a PD trip, I decided to see if I could shoot 53's through the CM. I loaded the same charge as I was running in the AI(but didn't chrono it), and shot 6 of them at 1000. All 6 made it and grouped decently(for 53's @1000).
I switched to 62 VT's in the 8 twist CM and run them @3730 with no issues.

Just wondering, how many total rounds did you get on either barrel?

Yes, you will be fine.
Keep us posted on your load and results. The 62Vt would be sweet.

IThey are what I do plan on shooting. Hopefully

I'm at 1000 rounds on the Creed and only about .010" of freebore erosion(surprising low).
I'm at about 500 rounds on the AI with about .020" of freebore wear. I'm bringing 250 rounds for it this year, but only as a backup gun. I'm going to set the barrel back as a 22BR for next year, so I want to save wear on it, if possible.
