Researched your numbers....these would put your muzzle vecocity at between 3300-3400 fps....Maybe out of a 6mm/06...Wildcat or other over-bore case but not a factory 243! There's not one manual out there that confirms this especally out of 23" barrel...suppose this could be the reason for no load data to confirm your numbers??.. I Think so !!..the only smoke out there right now is what you are trying to send down-range to this Forum...I know I'm not the only one who sees the HAZE in your threads...have also read some of your other replies and if you want to engage me or others on the Forum do it out of "intelligence" and not intimidation.
You better be afraid of a ghost!!
