I’ve been floating around the hide for a lot of years now and have enjoyed every minute of it. Every now and again I find myself having a hissy fit when I cannot find the information I am looking for. It has finally donned on me that maybe I should be a part of the solution and post the things that I had been looking for and can’t find. My hope is it may help the next guy that is looking.
I’ve recently started down the road of load development for my 22 Creedmoor. My intention is to use 85.5 Berger’s as I have 1000 of them. The rifle is as follows.
Defiance ruckus
Manners EH1 gen 2 mini chassis
24” carbon 7 twist Paradigm barrel
Jewel
So far I have done a 10 round pressure test using Peterson LRP brass Fed 210 match and H4350 loaded at 2.700 The results were I found slight pressure at 37 grains in the form of flattened primers, that charge resulted in 3115fps. There was an interesting flat spot in speed between 36.6 and 36.8 yielding velocitys of 3082fps and 3085fps. I’m sure the barrel is gunna speed up so I guess we will see. It seems like a long stretch to copper creeks advertised 3250fps with 4350 and the 85.5
Moving forward I think I will pressure test some more powders behind the 85.5s to help some people if you are interested let me know.
I have the following powders I am willing to try
H4350
Hybrid 100V
RL26
H1000
H4831SC
N160
N165
IMR 7828
IMR 7977
Retumbo
If anyone has any interest in testing these powders before stocking up let me know. For myself I think I’ll try some slower powders and see if I can get a bit more speed in a stable node as coyote season is upon us.
Thanks for reading. Happy shooting
