Please excuse my ignorance, but what does “230,000 rpms” mean? I am not familiar with that measurement?
230,000 rpms is revolutions per minute,if you think a dentists drill screams that is nothing compared to that.
I will get flamed for it being a lightweight round at 55 grains,but the speed it leaves the barrel out to three hundred yards is laser straight unless there is a strong quartering wind.
if you are ever around one and get a chance to shoot it,try shooting it into the wind,you will hear many many shock waves as it travels down range.
they use to be called barrel burners as they could be loaded to over 4500 fps.
todays barrel materials and powders are superior to back then and the problem is not as is it was in those days.
in actuality it wasnt the barrel that got burned out,it was the entry into the barrel that suffered from corrosive powders and accuracy suffered due to it.
mine is a ruger M77 stainless varmint barrel with a laminated stock,weighs nine pounds out of the box without scope.
I have ran over a thousand rounds through it using hogdons blc2 powder at 3890 fps and havent had to change the scope at all to compensate for wear and I am dialed in at 300 yards.
