    -- "Light clothing" does not offer much information when projectile testing and is generally a waste of time.

    -- "4 layer denim" (4LD) is a much better test of handgun bullet ability to robustly expand than "heavy clothing".

    -- When using supersonic rifle projectiles, any cloth barriers are fairly irrelevant and don't change test results.

    -- Get some old soft body armor panels and use them to wrap the gel block to contain any projectiles that exit the block.

    -- If during a test shot an accurate chrono reading is lost, fire 5-10 shots from the same box of ammo to get an average velocity measurement so you have an informed estimate of potential velocity; note that particularly with rifle loads, sometimes it helps to move the chrono away from the muzzle a bit...

    Still I do see some practicality to slow and quiet ammo. I'm just not sure we'll get what we are accustomed to seeing from more traditional rifle rounds.

    +1 I am interested in it in full rifle power form as well. Largely for deer hunting. A new load from Federal

    The all copper monolithic rounds will do much better as they are designed for those velocities.

    These aren't much more than the Hornady and will perform better: https://moamunitions.com/products/30...xpanding-round

    I'll have to get some of that to try.

    Interesting they're choosing a bullet specifically designed to expand for DoD ops.

    The US did not ratify that provision of the 1899 Hague Accord, and the Hague Accord only applies in conflicts between other signatories of the Hague Accord. The US has just been playing along with that rule for NATO ammo consistency and funsies, really.

    So we're not obligated to follow that rule, and it wouldn't apply in combat against insurgencies anyway.

    That is my understanding as well....
