    Ok so I did't have much to do tonight so I went into Ballistics by the
    inch and typed in several popular rounds and was looking at how many
    ft lbs of energy each one produces. All data is from a 16 inch barrel.

    First off is the 9mm's

    Cor Bon 115 gr JHP +P 594.01 ft lbs 805.37 joules

    Speer 124 gr Gold Dot Short Barrel 523.73 ft lbs 710.08 joules

    Federal 115 gr JHP 428.34 ft lbs 580.76 joules

    Federal 147 gr Hydra-Shok JHP 375.90 ft lbs 509.65 joules
    ----------------------------------------------------------

    Now the .40's

    Cor Bon 135 gr JHP 838.23 ft lbs 1136.48 joules

    Cor Bon 140 gr DPX 638.52 ft lbs 865.72 joules

    Federal 135 gr Hydra-Shok JHP low recoil 586.01 ft lbs 794.52 joules

    Speer 180 gr Gold Dot Short Barrel 522.30 ft lbs 708.15 joules

    Federal 165 gr Hydra-Shok JHP 430.62 ft lbs 583.85 joules

    --------------------------------------------------------

    Now the .45's

    Cor Bon 165 gr JHP +P 763.08 ft lbs 1034.60 joules

    Cor Bon 200 gr JHP +P 679.71 ft lbs 921.57 joules

    Cor Bon 185 gr DPX +P 620.63 ft lbs 841.46 joules

    Federal 185 gr Hi-Shok JHP 511.75 ft lbs 693.84 joules

    Federal 230 gr Hydra-Shok JHP 504.73 ft lbs 684.32 joules

    ---------------------------------------------------------

    Strongest load was

    .40 caliber Cor Bon 135 gr JHP 838.23 ft lbs 1136.48 joules

    Second place was

    .45 caliber Cor Bon 165 gr JHP +P 763.08 ft lbs 1034.60 joules

    Weakest load was

    .9mm Federal 147 gr Hydra-Shok JHP 375.90 ft lbs 509.65 joules

    That's an interesting data set, and I may have to go play around on that site, myself. I kind of wonder if a lot of the .45 loads actually might do better with an inch or so knocked off the barrel length. Given the lower pressure of the round, I wonder if the last few inches of barrel length are maybe causing more drag than the amount of pressure created from the expanding gasses.

    Yeah its a cool site. Just for fun I tried to find something that was close in energy to the hottest .40 caliber round.

    .40 caliber Cor Bon 135 gr JHP 838.23 ft lbs 1136.48 joules

    Federal 240 gr Hydra-Shok JHP .44 magnum 4 inch 834.22 ft lbs 1131.05 joules

    So the hottest .40 beat the .44 magnum out of a 4 in...but the was a heavy round the lighter ones might have better performance.

    Ok I am tired of doing math now :foilhat:

    Should match or exceed the Cor-Bon, as Underwood has been recently
    developed with the latest powders and data acquisition available ;)
    These run 76¢ per round, plus shipping. My last Underwood order was
    shipped for $12.xx for a shipping weight of 10 pounds! :D (240 rds 10mm)

    I'll let you know how it shoots ASAP ;)

    Another ME and Ballistics Calculator for your enjoyment...

    PS: Underwood's 135 grain is 50 FPS Faster in the G23 (4" barrel) than
    the CorBon 135 in the BBTI test, per Underwood's site:

    I suspect the 165 grain 40 cal is right with the 165 gr 45 ACP +P you list here.
    That's the reason I was seeking out the Underwood, Hot-Rod Ammo at
    "off the shelf" ammo prices!

    Depending on the load, the .45 seems to do best at 16-18 inches of barrel, with more at the 16 inch length.

    Mole can you use a chrony to see what the energy is? It would
    be fun to know.

    Interestingly enough, the 230gr Hi-Shock and 165gr Hydra-Shock velocities actually drop from 15" to 16". In general, though, 16" seems to be the ideal barrel length. Cool site!

    1/2M(ass) times V(elocity)^2. So if you know the mass of the bullet and its speed, energy is quick math. The BBTI website is a good ballpark but it's measuring from a sealed breach and isn't an apples to apples. The blowback action of the HP's will suck a lot of additional energy out of the equation.

    I'm starting to lean more towards getting the jcp and 4095ts next....

    Stop! Wait until you've gotten the 4595, first! You will resent the 4095 for its inadequacy if you don't get it, first, and you will tear your hair from your scalp in anguish.

    For the peace of your soul and the sanctity of your scalp, get the 4595, first.

    Back in the good old days, like 5 BT (that's 5 years Before TS stocks) the 4095 was available...and there was no 4595.

    So, I got a 4095 first.

    No anguish, no inadequacy, in fact, the .40 does better than the .45 in most handguns, and does even MORE better out of the carbine than the .45.;)

    Pfffft.:rolleyes:

    I bought a 4095 first as well, because the LGS sold his last 4595 a couple of days earlier.

    I doubt I suffer much in the way Think has proposed if and when I do pick up a 4595.

    Yeah, right. You both have bald patches on your heads, and when you look at your 4095s, you just sneer and shake your heads, muttering things about mutant cartridges.

    WIZ has a JHP, he should get the 4595 first, makes sense. No need to argue!
    I just hope he does not get T1st's inadequacy complex... :p
