Effective range for a longslide?

[Tspeis]

For the G20 and G21, what do you guys think would be the maximum effective range of the two with 6 inch barrels? 10mm with a 6 inch barrel and longslide? 45acp with a 6 inch barrel and longslide? When i say "maximum effective range", i want to know how far you guys think one of these pistols could fire a round, and how far it could possibly go while still being considered lethal. How far could it possibly go and still have knockdown potential?


Do you think it would be possible to hit a target at 200 yards? 300? I know i'm probably pushing it here, how about even 400-500 yards?


Any feedback would be greatly appreciated.

Thanks,

400-500yrds?!? ;i

In a word...no.

However I think 50 yards would be reasonable with a cool shot, and traditional sights. Here's a suggestion, take a paper plate and set it out to 150 yards. Next try and hit it with a longslide G20/21. Observe results.;)

[MPG1737]

That being said, many 10mm loads retain quite a bit of momentum even at 200yrds+.

Average shooter:25yds
Very good: 100yds
Master: 150yds
Given enough time and ammunition 400yds is doable and the energy at that range will still hurt you. Even a master would be very hard pressed to hit a three to five foot square at 400 with regularity.
Nothing you can carry will have knockdown power, even at the muzzle. If it did it would knock you down when you shot it, Newton discovered this a long time ago.

Either of these two pistols in 6 inch dressing means an aftermarket barrel, i.e. glock doesn't manufacture a half footer for those. Your choice of barrel supplier would have to factor in to how well "shooter A" could do with either. not that i have any preference, but let me just throw it out that Bar-Sto would be a great choice.

There is a substantial velocity difference between full house 10mm and "standard velocity" .45. Perhaps this would lend itself to greater effective range with the 10mm? Any thoughts from the group?

We hit the 2X2 feet gong occationally at 100 yards, so it is possible to hit further.

[Tspeis]

Ok, lets say we rule out the shooter's ability, what are the guns themselves capable of? I know an average shooter could get around 3 to 5 inch groups at 25 yards. I want to know what the gun is capable of despite the ability of the shooter.

In a perfect world 5" at 25 yards=20" at 100 yards and 80" at 400 yards. YRMV.
Handguns are not long range propositions for most mortals.
Best case- 2" at 25 yards= 8" at 100 and 32" at 400.

[Tspeis]

Ok, so if those are the estimated groups, then i just have one last question. Would these rounds, 10mm or 45, either one, have enough kinetic energy for force to knock down oh lets say a steel plate from that range. Basically what i'm curious about is could these rounds still have lethal potential at that range.

Sorry if i've dragged this question out. I've done SOME handgun shooting, but have yet to try anything like this, that's why i'm curious. I don't know if there are any long range handgun competitions anywhere, but if there are i'd consider joining once i get better at shooting.

Depends on the steel plates weight. Yes, a pistol can inflict a fatal wound at 400+ yards. Early Army tests stated the .45 ACP would penetrate 4" of white pine at 250 yards. For remaining energy at any range consult ballistics tables or programs.
Even the small 5.56mm service round will go through a steel helmet at 1300 meters.

Here's a question i have, but it's kind of off topic here. Everyone says you can't hit a target at over a mile away with a 308. However, i'm not curious as to whether I can hit something with it, i'm curious as to what the BULLET is capable of. Is the 308 capable of delivering a fatal shot out to a mile?

[jungle]

Look at any old service rifle. Ladder sights that adjust to 2000 meters or so. The trajectory gets awful steep out there, but it will still punch a hole through a man. Massed rifle fire at that range against an area target was a common tactic in WWI.

Well, maybe if you put a sholder stock and scope on them, you could reliably get out as far as 200 max.

I would just invest in the carbine conversion for it.;f

[TED]

Indeed, that was kind of what I was getting at.
