Edgun Metal valve stem testing started!
Installed metal valve stem with Delrin seat on my .22 R3. no other adjustment made. all shots was cronyed.
speed of stock stem 880fps shooting 18.1g 200b fill to 105b 70 shots ES 12fps
speed of metal stem 895fps shooting 18.1g 200b fill to 105b 74 shots ES 9fps
Total shot today: 210
all shots are cronyed, when I see inconsistency in the shots —I will inspect the valve stem. will try to shot 50 to 100 shots a day. will install on .30 cal tomorrow and mail one to OldGoat for testing.
