Does anyone shoot 70 grain Berger vld in 22 creedmoor. I'm doing some tinkering with it and getting faint ejector marks at 41 H4350. Can anyone run quick load on it. I also have h1000, r15,19,22,23,25 thanks

Peterson small primer brass
QL shows 41 grains of H4350 is roughly 10,000 psi under max. QL show max of max for H4350 near 43.3. I've attached QL data for H4350, RL15, RL19, RL22 and RL23. I did not include H1000 and RL23 as both require around 115% load density to attain near max pressure.

Also finding my 22CM finds pressure 10-12K under suggested max PSI. Verified charges with GRT same results. It's accurate so NBD but having same results as you.
Whew only 10k of max last summer I was running H4350 and 69 grain tmk up to 47 grain's before I torched a primer and pocket! No stiff bolt or wicked ejector marks. Curtis action and Peterson lrp brass must have been hiding pressure! Thank you for your research and enlightenment!!!

Yes lots of folks running crazy pressures in 22 Creedmoor because the brass and rifles quality can hide excessive pressure and they just pull data from places like this.
Best suggestion is go to Hodgdon website as they have good pressure tested data and if your velocities are much higher with same or shorter barrels then you are probably above acceptable pressure limits.
You can run there but at your own risk and many do but that's the nature of loading wildcats.

I know I was running over max pressures when I started shooting 22CM. I have since idled back my loads after seeing published load data. There are some good starting loads here as well as info on over-pressure loadings.

Since its’ inception, in 2007 by Hornady, the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the...
