    After an embarrassingly long time of owning my Glock my Glock 20sf, I finally loaded up fifty 165 grain TMJ's with Unique.

    I was shaking like a prom queen as I loaded up my first magazine. I think I did okay though. I kind of surrounded the bullseye and talked real mean to it.

    Once I settled down and got used to the trigger (I'm spoiled by the trigger on my G34) I think I improved my second 10 round group.
    SEVEN YARDS - I think I'll keep it. No Glock bulges at 1,020 fps...

    Nice work. Unique is one of my favorite plinking powders for 10mm. What's up with the Austin Powers pic?

    Nice shooting a G20SF is on my short list for my next gun. Already have Unique on hand and ordered some WSF yesterday.

    Thanks.
    Yeah, I've liked Unique in the past for other calibers. One of manuals listed this load as the most accurate for a 170m grain. Seems to work for 165grain too.
    The Austin Powers picture is actually a freezer magnet and it is holding my latest target on the fridge. Honest, I'm not trying to give anybody a hint or anything. My garage decorations are real fancy aren't they?

    I saw your sig and I thought someone called the fire department. "It's okay, I'm not really stuck on the ceiling".
    I was surprised how manageable the G20 was. After I shot the G20, I shot my Glock 34 and I brought some old hollowpoints which had been loaded up with a Blue Dot load from an old Sierra manual. When I got home, I checked my other manuals and they were like two grains lighter than the load I shot today. I was wondering why my 10mm was easier to shoot than my 9mm. :rofl:

    I think you'll enjoy having a Glock 20SF. That's the most fun I've had for a long time (but I need to get out more).

    Thanks. It was a big surprise to me. I had surgery on my hand two months ago and I have a relatively sensitive scar in the palm of my hand. I was a little worried that my shooting days were over and I was going flinch big time with a 10mm.

    I was also happy my reloads didn't go kaboom too.

    6.5 Grains of Unique

    Hey G33. I recently looked up a bunch of your posts in the .357 sig forum. The Lone Wolf conversion barrel for my Glock 20 is a few steps down on my wish list, but it is there.

    You chrono those over 6.5 gr. of Unique, by any chance?

    No. I had to guess-timate the speed.

    6.4-gr. Unique under a 180-gr. FMJ is currently my fave. Behaves very nicely in my stock G20.

    It's weird guestimating without a chronograph.
    I'm using "The Complete Relaoding Guide for the 10mm."
    When I pull the Nosler data out of it, it says:
    170 grain HP - 6.5 grains of Unique = 1025 fps
    180 grain HP - 6.3 grains of Unique = 1051 fps

    You go up in bullet weight. You decrease the powder and the fps increases. This stuff is so non intuitive.

    At 180 grain, the most accurate load is listed as 5.8 grains of Unique at 993 fps.

    :faint: I'll stop trying to guess-timate now. I looked through my manuals and the Lyman manual listed a speed for the 165 grain with 6.5 grains of Unique as 1012 fps (using a Universal receiver with a 5 inch barrel).

  14. doesn't that make them 10mm light?

    I believe that my testing, while not extensive, has shown that the 10mm light can consistently penetrate paper.

    Now, if somebody wants to supply me with some ballistics gel, or if R. Lee Erme wants to invite me over to blast some water melons, I'll give the old powder bar bolt on my Dillon 550 a twist and crank out some blasting ammo.

  16. don't get me wrong. I think that was fantastic shooting. better then i could do. I was referring to the point that shooting that round would in fact be as soft shooting if not softer that the 34 with faster Hp's. Plus i like to practice with what i may have to use. It lets me become familiar with its characteristics.

    I'm not sure about the muzzle energy, but imagine my surprise when after shooting the 10mm, my 34 was kicking harder. :wow:

    Now I realize that I would like to pick an accurate load for my 9mm and reload all of that empty brass that I have laying around.

    That's always been my philosophy on my other rounds and it has worked out great. (9mm = 115 grain hot, 45 ACP = 185 grain 900 fps, .357 slightly hotter than +P so I can train with it in my SP101, .44 Mag 185 grain mild loads for controllability).
    I'm not sure how to handle my self defense loads in the 10mm yet.
    I have 450 rounds of 165 grain TMJ and 500 rounds of 180 grain TMJ to load up. Currently, I only have 700 rounds of Starline 10mm brass.
    So, I'm going to load this stuff up first and shoot some of it up.

    Right now, my main goal is to develop accurate loads that do not get the Glock bulge.

    I will pick up a box of bulk hollowpoints some time in the near future. I would really like to load up some 135 grain bullets. But, I'm afraid that if I'm going to avoid bulged brass, I will need to stay in the 10mm light category.... at least for now. Also, I haven't found any bulk bullets in 135 grain (just expensive boxes of 100).


    ..... So, with my goals in mind,...
    • Bulk Bullets
    • no bulge in the brass
    • decent self defense load
    I'm thinking about a 155 grain load which is outside the range of 10mm light. We'll see how well the brass wears.

    But right now, I feel like the heavier gun gives me a real advantage for follow on shots and I think it is just a matter of ratcheting it up until the brass shows excessive wear (smilies) and then back it back down.

    Anybody got a preferred self defense load that they would like to post?

    Normal case swelling no significant bulging @ the bottom of case out of my G20 4.06 barrel and 6 inch Glock barrel. Less case swell with Lonewolf Distributors barrel. I use LWD barrel for range only since I never have had any FTF with Glock Barrel but have had a few with the Lonewolf. By the way make sure of your crimp, the crimp diameter should not be less than .421 inches. Max load for Power Pistol with 165gr JHP is 10.0 grains.
