DRT ammo sounds like a take-off on Glaser Safety Slugs, except instead of fine lead birdshot, they're using smaller pieces - almost a powder - of tungsten. (What else would be "denser than lead" and still semi-affordable?)
I note that after the original stuff was on the market for a while, Glaser introduced another line of ammo with
larger shot sizes to address concerns about penetration.
If DRT ammo's accuracy
is "better than handloads" I imagine shooters using their ammo already hold all the benchrest and match rifle records at Camp Perry, Wimbledon, etc., right?
As for Cheaper Than Dirt . . . I ordered from them
once, paying both shipping and sales tax. They had a promotion for some "freebies" which weren't included in my order. When I called them and asked where the premiums were, the woman who answered their phone
laughed at me and hung up. <obscenity> <obscenity> <profane obscenity>
I love hor the bullet spins at 160,000 rpm. What kind of rifling does the barrel have to make that happen?
Assume a rifling twist of 1 turn in 12 inches, and MV of 3000 ft/sec. That equates to 3000 revolutions per second. Multiply by 60 seconds per minute, get 180,000 RPM. Fiddle a bit with twist or velocity, and you can easily get 160,000 rpm.
