The 22 creedmoor thread

[mxgsfmdpx]

Does anyone have load data published for 22 creed/h4350 and 88 eldm? I have Hornady and it doesn’t have any h4350 data past 80 grainers. I thought about grabbing a hodgdon manual but didn’t want to waste the money if they are missing it too.

Or if someone just wants to tell me a general idea of where they hit pressure that would suffice too

For reference- Peterson LRP, cci200, h4350, 88 eldm is what I’m looking to play with. I also have some 80s and h1000 but I see data on those.

Start around 36 and work up. You'll likely be fine up past 40, but better to be safe.

@satchamo i just got done working a load on my new rifle, I settled at 40.5g h4350 with the 88g ELDM, CCI 200, Peterson brass. I worked up from 38 to 41.5 and started getting a slight ejector mark at 41.5 in my rifle so I dropped it 1 grain and worked it from there. That’s 8 shots at 1/2” tonight, the high one was before I adjusted my scope. I’m super excited to put this gun to work this winter!

Use caution if you’re loading that high in a new barrel.

Iv seen things pressure up as that bore starts getting rough during break in.

Good to know - I only loaded a single round of a few powder charges to test for pressure signs. Plan to just run a grain under the first charge I see pressure on.

Unrelated… I’m looking at hornadys manual for 22 creed and for h4350 and the 80 gr eldm, they’re showing book max at 37.7 gr. Do lighter bullets pressure up faster or is it just the shit brass they test with showing pressure sooner?

Hornady tests with pressure equipment not pressure signs on brass.

Most of the internet is just okay shooting 70k psi loads I think.

I had pressure after 39 grains of h4350 and thought it was a touch fast of a powder for 22 creed.

Duh that makes sense. Im not sure why I thought a company like Hornady would be loading and visually inspecting thanks!

So i tried some 75 ELDMs couple different times. They seems like they would shoot a few shots close together and then a random flyer an inch away..

Then I tried the 80.5 Berger’s again and they all shot about in the same hole! Guess my barrel likes the Berger’s

Been talking to @hereinaz and getting pumped about getting mine and playing. Ordered a couple boxes of 69 grain ELD’s and 80 grain ELD’s to test when I get the rifle here. Y’all are killing me with all these pics

Like others have said with peterson lrp brass I ran from 37.5 to 41gr and still didn't have stiff bolt, flat primer or ejector mark. Decided on 39gr and have little over 150 rounds in without any issues. GRT says 63500k but plan to do a wet test next time I shoot. 20" 7 twist barrel 3060fps
