Stretching out the range for longer hits without running out of scope adjustment and you're back to. Terminal performance is only achieved with the Lehigh bullets pictured above. I want to build a.quite.hog killer that I can score accurate and deadly hits out to.150 yards or so but still be quite. What are realistic distances for subsonic rifle rounds like the. Originally Posted By: mavrick10_2000Originally Posted By: Lofty What is the best option for an accurate subsonic round that has good bullet selection for terminal performance as well? If you're actually trying to shoot a sub beyond 100yd, you might just as well be using a. No persnickety wildcat brass or dies, fits a myriad existing firearms, and 30cal projos are far from rare. My nominee is the lowly and ubiquitous 7.62x39, loaded with a biggie open base boattail, seated backward. 30 cal, that minimal case capacities will still provide all the room one needs for the small propellant charges required, and will do it with higher efficiency. I think that in practical terms, it makes little sense to be shooting bigger than. But actually, the resulting teardrop profile is very stable at low RPM's, nearly ideal for subsonic (aerodynamic) penetration, and the open base exposed lead projectile's front is very close to being a trashcan hollowpoint for terminal performance (you need every bit you can get at those velocities). Slow arcing trajectories and inconstant winds can make a mockery of questions like this one.Īlso, subsonic aerodynamics are kinda different from the kind of shooting the rest of us do.įor instance, I sometimes suggest seating an open base boattail bullet backwards, and folks just sorta snicker. Proudly manufactured by American workers in Novi, Michigan.I don't really think that distances and subsonics are all that compatible. Sold in 250 round packages - buy bulk and save with tiered pricing discounts! As with all of our ammunition, these are 100% hand inspected using precision cut gauges to ensure functionality in custom pistols commonly found in competition including those manufactured by STI, Cheeley Custom, Hayes Custom Guns, and others.ĩmm 147 grain is a naturally subsonic round making it a perfect choice for use with silencers and suppressors. Used by all our sponsored competitive shooters including Matt Koopikka, Nick Molina, Rick Birdsall, and others. See why these are such a hit among the competition crowd including 3 Gun, IDPA, and USPSA! Less recoil and muzzle rise allows you to keep the sights on target for quick double taps, while a heavy projectile provides enough kinetic energy to knock down steel plates even when struck off-center.
