22 Creedmoor Magnum (+ Peak )

[Huntnpack 2]

Starting this thread as a place for people interested. Anyone?

Let’s keep it related to 22 Creedmoor + Peak Only !!!

I’ll start off …….. I’m interested in the possibility of
A + Peak version.
It’d be nice if & when Federal comes out with it.

For my clarification, is this thread for 22 CM, or pushing the 22CM to a higher level?

I broadly categorize the 6.5CM as “standard”, 6CM as “magnum”, and 22CM as “ultra mag”.

Not that my categorizations are authoritative or even reasonable, but I would think much more powder behind a 22 would not see much benefit other than replacing brass, barrels, and powder jug more frequently.

Perhaps I’m wrong though…

I'm curious what kind of speeds you could get out of an 88 at 80k psi.

I also think a 10 twist shooting varmint bullets would be rad.

According to GRT, using N550 as the powder, it is predicting 3380 for the 88-grain ELDM out of a 24" barrel. Based on my experience with GRT, it is a little slow on it's velocity prediction model, so I would guess that 3400 fps is possible.

I’m considering in the short term a couple possibilities for a 22 CM + Peak

1) neck down 6.5 CM + Peak

2) if 6 CM + Peak comes available next,
neck that down

3) wait for 22 CM + Peak

Right now I’m leaning option 1.

How similar is this to the .22 UM that didn’t seem to do very well? It’ll be interesting to see if this is the magic ultra-fast 223 cartridge

I found a source for dies & bushings, so I’ll start there.
