    Today I braved the mud, took out my recently returned Glock 20sf (grip reduction), with the new Lone Wolf barrel and SS guide rod with captured #20 spring.

    Drug my Chrono with me along with an assortment of loads. I first ran some Winchester Silver tips:

    1179
    1200
    1208
    1191
    1210

    Then I ran 5 Remington 180 FMJ.

    1108
    1086
    1097
    1087
    1102

    Five Underwood 165 JHP* My favorite load:wavey:

    1407
    1380
    1409
    1450
    1418

    Five Underwood 200 gr. XTP

    1173
    1188
    1178
    1190
    1194

    Then 5 of my reloads of 165 FMJ
    1406
    1391
    1390
    1390
    1384

    Then did some target practice shooting about 90 more rounds of my reloads. All were accurate enough at 15 yards, and the gun ran flawlessly with the new barrel, spring, and guide rod. I couldn't be happier. The grip reduction and stippling felt great!

    Could someone with one of those fancy ballistic calculators figure the energy for the 200 gr. and 165 gr. Underwoods?

    No need for a fancy calculator. Any calculator will do. First find the average velocity. The formula for energy is (velocity X velocity X bullet weight)/450,400

    Velocity in fps and bullet weight in grains.

    The 200 grainers energy of the average velocity: ME = 623 lb/ft
    The 165 grainers energy of the average velocity: ME = 731 lb/ft

    Nice report. Good looking grip job. Sounds like a very happy day at the range.

    Fantastic report..!..Thanks..!

    I reload using silvertip 175 grains. Kind of expensive but at least I know mine run at 1300+ FPS. :supergrin:

    Love the numbers on UNDERWOOD...I am very impressed with them stepping up with quality high speed ammo...!

    Your GLOCK looks great. I love the grip.!

    It really is the PERFECT HANDGUN. No doubt about it.

    Take care
    Bob :cool:

    Good report, Rcd.

    Were those older Silvertips?

    I bought them from Cabelas this fall. If I'm reading the numbers on the box right, they were made in April of 2010. Is that considered old?


    And thanks Bob, that means a lot coming from you. Edit to add, I've got a couple hundred of those Silvertips for reloading too. Along with a couple boxes of 165gr. Gold Dots.

    I don't think 2010 is considered old (IMO). I guess that's how they are loading them now, 175 grains at a little below 1200 average.

    where did you get your grip reduction and how did it "improve" the grip for you? does it point better for you? where did they reduce it? just the hump or the "length of pull" too?

    Been eyeballing these but never been able to get my mits on one to try out so havnt pulled the trigger on it.

    Do you carry IWB,would like to know from someone who does? I have been thinking about doing the same thing but not sure how it feels against the skin.

    I looked up the guys that tested a bunch of 10mm loads and put them on YouTube. Also goes by 10mm Ammo on Facebook. His chrono results mirror mine. Were you under the impression they were faster?

    Yes, I believe when the Silvertip first came out they were pushing the 175 grain bullet at closer to 1280. Winchester then began downloading them in the more recent years. They are still respectable though. I was curious as to how Winchester was loading them as of late.

    Yes...I have an older box from 1993 and they crank out at 1250 FPS. (Box Flap speed was printed as 1290 FPS).

    These days Winchester 175s do average 1160.

    :shocked: Much lower. Wonder why........

    Take care
    Bob

    I'd guess somebody had a kaboom, blamed Winchester, maybe even found them a shyster lawyer and sued them. Thus causing them to lower the power. There was a rumor going around similar to this about Double Tap. That may be why his numbers are down..............:dunno:
