    I picked up some Federal .40S&W 135gr. JHP's (XM40HA) are these considered HST's?

    Being that they are 135gr. how far are they from matching the ballistics of the 124gr. .357SIG?

    Any additional info regarding this particular round would be appreciated from those who have tried it...maybe muzzle velocity/energy...

    Thanks

    An excellent coyote round
    The extra mm at the same weight and speed kills the 40's penetration compared to the .357 bullet in the 357 sig

    I have shot them at the range, pretty good on recoil and getting back on target after multiple shots. I don't know about the penetration and other ballistic stuff

    I'm not sure I understand... Does this round not do a good job comparing to a 124gr 357SIG?

    I figured if you got the 40 light enough, it could come pretty close to the muzzle energy/velocity of the 357SIG?

    Don't try to turn the 40S&W into a 357sig
    You compromise too much:faint:
    The 357 sig with 125-147 is great-at 180:faint:
    the 40 S&W with 165-180 is also great
    If want 357sig ballistics-GET A 357sig-don't ruin a 40S&W to do so unless your huntin crows,coyotes,and leprechauns with it

    Doesn't Border Patrol use a 135gr .40?

    Are they HSTs? I don't know. You can go to Federal website and find out. I'm at a computer with a 56k internet speed right now and am not going to take the time.

    That said, if you want to see how top velocity loads in 357SIG and 40 S&W compare, here are the Double Tap results from Mike McNett -

    All of these tests were done using 10% ballistic gelatin provided by Vyse gelatin using all FBI protocols and 4 layers of denim and two layers of light cotton T-shirt in front of the gelatin.

    DoubleTap .40 S&W Penetration / expansion
    135gr. Nosler JHP @ 1375fps - 12.10" / .72" (565 ft-lbs)
    155gr Gold Dot JHP @ 1275fps - 13.00" / .76" (560 ft-lbs)
    165gr Gold Dot JHP @ 1200fps - 14.0" / .70" (530 ft-lbs)
    180gr Gold Dot JHP @ 1100fps - 14.75" / .68" (485 ft-lbs)
    200gr XTP @ 1050fps - 17.75" / .59" (490 ft-lbs)


    DoubleTap .357 Sig
    115gr Gold Dot JHP @ 1550fps - 12.25" / .71" (615 ft-lbs)
    125gr Gold Dot JHP @ 1450fps - 14.5" / .66" (585 ft-lbs)
    147gr Gold Dot JHP @ 1250fps - 14.75" / .73" (510 ft-lbs)

    I added the kinetic energy numbers for each round in red rounded to the nearest 5 ft-lbs.

    That's just to give you a basic comparison with the bullet designs tested. Exactly how those Federal rounds compare is still unanswered. Even though that may be a let down to you, it also shows you you can't arbitrarily compare any one round of what ever cartridge/caliber to all 357 SIG rounds as a whole, as they are not created equal.

    Now I suggest you go to Federals website (federalcartride.com or federalpremium.com) and check out the claimed velocity and energy numbers along with what bullet they're actually using. Then you should be able to make a pretty educated decision on where it stands, and then maybe do some backyard testing from there if possible unless someone else can shed some light on the specific bullets performance.

    Good Shooting,
    Craig
