22 Creedmoor load data

[Hammerdown22]

Would 223wssm load data work with 22 Creedmoor since the case capacity are the same ?

Off the top of my head, I would back down abt 5-6gr and as I worked up, I would consider starting with .4-.5gr increases and as I passed the 3-4 gr mark, dropping to .2 increases. Load only one at ea wgt, jump abt .010" to cover any ojive variations with no possible pressure spikes from land contact and go till things get sticky or cratering. If you have a chrono, watch for plateau with no increase in velocity, maybe a drop signalling No More powder. I'd also pick a temp stable pwdr. for openers.
This is for establishing a safe load pwdr range only. After a handle on charge wgt is gained, then do all the tweaking you want.
I realize you didn't ask for methodology so how about a pass?
Maybe you or someone else can improve on my suggestions?

22-250ai data should be pretty close.

It's basically the same cartridge.

Yes, they are. So is the standard 220 Swift (which is really easy to find load data for).

What bullet are you planning on running? The 80.5gn Berger has a sweet spot around 42.5-43.0 in mine with H4350, gap 6cm brass and F210M.
