Hello my friends

I went with my wife to the range to try my new Glock-17, my girl used a Savage Mark II that she really love:rolleyes:, since the pistol lines where all taken we went to the Rifle side:cool:, the minimum distance is 25 yards so i shot about 50 rounds at 25 yards, "this gun is accurate" :Di said to my wife, while she was shooting at her target at 50 yards. At this point i felt like i have shot this gun for a long time, i had the fixed sight all workout, so what hell...i loaded the pistol and start practicing at 50 yards with good results :D, after a few rounds i decided to move the target all the way back to 100 yards (yeah you can call me crazy, my girl called me crazy too, even an old fella next to me was like "Pss... forget it") loaded a full magazine 17 rounds and Bang.. Bang... Bang...all 17 rounds were fired, by the time i saw the target this was my face ---> :what: BTW here's a picture of the target with a few .22lr shots that my wife shots while spotting my shots from her rifle.

please let me know how well i did for a first time glock user ;)

Thank you.
Sarduy.

you hit the target that is alot more than most people can say at shooting a handgun at 100. even though it is impractical i still like to do it every once in a while just to see that i can. and it is fun too, especially when you get the hits that you wanted. great job, and i say that is real good for a first time, keep shooting, and applying the fundamentals. the hardest part is figuring out the drop of the bullet at that range, but it seems you have that almost figured out .
 
'Course if it were a .45 ACP the bullets would all be in the dirt before 50...
Several months ago, I had the opportunity to do some 100 yard handgun shooting with some friends. Guns used were a 9mm CZ75, a Beretta 92FS and a 1911 in .45ACP.

All of them were capable of making hits on a human sized torso target (somewhat larger than the paper target in the picture above) without having to hold off of the target. The trajectories obviously weren't that different, the small variations in the exact point of aim/point of impact in the various pistols made more difference.

Three of the four shooters present were able to use any of the three handguns to put every round on a human sized torso target at 100 yards once the proper hold for that handgun was determined. IIRC, one needed a center hold on the "belt" of the torso, another required that you aim at the left shoulder, can't remember the hold for the third pistol.
 
where was your point of aim?

with a 9mm i would be aiming for the top of the page, maybe higher...

at 40 yards in IPSC we usually aim 2-4 inches high depending on what equipment we're shooting... so at 100 yards, as the drop rate increases, i wouldn't be surprised if you needed 6-10" of compensation.

hm.... a 9mm has many velocities, but for simplicity let's use a 1200 fps bullet... 300 feet to the target, so .25 seconds... 9.8 m/s^2... aw crap. nevermind. i got a C- in physics.
 
according to what I calculated and using the numbers you provided the drop (ignoring drag) is 2.0125 ft or 24.15 inches.

Though using raw acceleration and velocity calculations may be suspect because it would go under the assumption of a perfectly level barrel... and in practice the bullet is actually arcing upwards at fist. So I don't know how valid that number is.
 
really? lemme try it.

yeah, i guess so. from 24 inches the pen hit the floor pretty quick while watching a smooth sweep secondhand.

on long distance classifiers and steel matches, when the light is behind the shooter, it's easy to see the bullets flying downrange. interesting to watch. the 45 is really easy to track and you can see 'em drop like heck, lol.

come to think of it, when i shoot an IPSC target, i aim right where the charlie meets the bravo at 35 yards on merle's standards and four bill drill, and the group usually centers in teh middle of the alpha... about 6" lower than POA on a 930 fps bullet.
 
wait a sec, that gives me an idea. so long as a gun is sighted in properly.... i wonder if you could guesstimate whether one load is faster or slower than another load by watching POI over the same POA.

Using the same grain bullet and having the firearm positioned the same each time I would think that would work just fine.
 
bullet weight shouldn't matter in theory, since acceleration due to gravity isn't affected by weight.... the vertical air resistance from falling should be pretty negligible.

That is completely true in theory. However in practice the heavier bullet weight will almost universally have a higher impact location from being in the barrel longer and effected by recoil longer. Which is why POI changes so much with a change in bullet weight. At handgun ranges the velocity actually doesn't change the poi as much as this change of bullet weight does. This might not matter from a truly fixed barrel like on a universal receiver.

Oh and by the way, I think that is some pretty good shooting for 100 yards.
 
Old time revolver shooters often would take on B-27 silhouette targets at 100 yards, even with 2" snubbies, such as my pet Detective Special. I have news for some folks - if you can hit center-of-mass at this distance the shooting isn't "impractical."

It is no harder to hit at 100 yards - or even further - then it is at 25 yards. It is unlikely that a Glock 17 is less accurate then a Detective Special, and a match-tuned Colt Government Model will usually beat the Glock. If you can't hit a target at 100 yards it isn't the gun's fault.

There are two tricks. First, start with a very large target so that you can determine the trajectory of your bullets at that range. You will undoubtedly have to hold higher then you usually do. Second, pay particular attention to the sight picture, and let the visual image of the target blur. The last thing is to tell yourself that you can – because you really can.
 
yeah i understand. but at that point, yeah the velocity changes and that's the only thing i was looking to measure as a thumb type rule.

The reason I mentioned the POI change due to bullet weight/recoil was because in order to determine the relative speed of your rounds due to POI, you would need to remove the variable of bullet weight to get useful data.
 
I regularly shoot my pistols at 50 yards when on the rifle range. I shoot at 8.5 x 11" paper with 6 or 8" targets on them. My goal is to hit the paper. Generally I put the front post on the top edge of the paper and center the edges. I look for about 50-75% hits on the paper.

I think I'll take a USPSA target and some butcher paper along next time and see how things go at 100 yards.

There are times out in the woods when whatever else is out there needs to stay 50 yards away, at least.

When I started shooting pistols I was amazed that folks regularly shot at 25 yards. Now 50 seems like a reasonable distance.

Just about with anything, the best way to get better is to go outside the comfort zone or compete against those who are "better".
 
Nice shooting, very nice.

Now you are ready to join IHMSA and shoot Field Pistol. Most of your rounds would have hit the rams, and 9mm is just enough to knock them down.

My latest, greatest group is 4-5/8" at 50 yards (offhand) for 5 shots with a 1911 in .38 Super. I'm actually shooting better offhand with my 1911 than I am with my T/C Encore.

Turkeys at 75 yards re still a b!tch!
 
Another question.....was this offhand or bench rested?

I shoot my Ruger Mark III on the silhouette rifle range all the time. It's a blast to knock over the 100 yard bear with a pistol and I can hit it 9 out of 10 times from a bench rest. I shoot my 1911 just as well as my Ruger but it's not allowed on the silhouette range.

Huh? Guess you've never shot "Bullseye" (AKA Conventional Pistol) The weapon of choice is the 1911. Targets are set at 25 & 50 yards and all shot standing - one handed. I can hit a large dinner plate 10 for 10 at 50 yards one handed (on a good day)......and I have nowhere near the talent of the top shooters. Those guys will put all 10 in a circle smaller than a coffee can.
 
I won a lot of beer money in the Army hitting a 2" steel pipe target post on the pistol range at 100 yards.

With both 1911 match .45's, and a S&W Chiefs Special .38 Spl snubnose.

Standing on my hind legs with one hand.

At 100 yards a 200 grn SWC @920fps only drops about 6" at least in my .45.
At 150 yards a 130 grn Rn @1310fps is about the same from my .38super.

No, I never have, I don't even own a .45

Just being a tool...

Though I am pretty sure the average 9mm shoots flatter and faster than the average .45 ACP.
 
No one has mentioned an important factor: distance between the bore and the sights. If your sights are high enough above the barrel and you're zeroed at 25 yards, you would be hitting high at 100 yards.
