  • What cartridge for ELR | The High Road
    Stuff gets pretty squirrely long before a mile with a Dasher My Dasher loads are transonic by 1200, 300 Norma is still supersonic past a mile No comparison for drop or drift Having fun at a mile with a 1,000yrd rifle, sure, Dasher is fun, but reliable performance at a mile, nah, the 300 NM is the game
  • Labradar can track 485g 45-70 bullets to at least 200 yards!
    By the way, extending the measuring range of velocity versus distance for that 485g Lee bullet showed that indeed the BC is falling ramatically as the bullet slows, and in fact at 200 yards, it is at the same velocity as at 175 yards: View attachment 1172694 Very strange And causes me to again wonder: Is this some strange transonic effect?

    Last night when I got home, I pulled a few rounds and discovered that instead of loading 40 2gr I loaded 42 0 gr That was my mistake and a big one at that As for the 308 my goal is to not go transonic before 1000m My 178gr Hornady HPBT at 2620fps just make it there
  • Some Gun History | The High Road
    The guns shown in the video are matchlock guns The trigger mechanism forced the end of a burning length of string called a "match" down to a small hole in the rear of the barrel, igniting the gunpowder charge The user had to be able to light the match before using the gun, this in the days before there were things like lighters or even kitchen matches to start fires conveniently The video
  • Bullet 41-503, SWC | The High Road

  • State permit required to use public range | The High Road
    I just added it to my license Seems real overkill as my range now requires a safety class each year to get your permit to use it Which now, I wonder if that was in response to this change I joined that range so I have a place to shoot my larger stuff without bothering my neighbors I can shoot on my land, but am trying to be reasonable about it However, if the state takes this too far I
