Sabots range drop?
 
The remington premeiers copper, 10z. 1450fps range drop is 23" at 50yds according to the box. I'm hope this isn't the specs for a rifled barrel shooting them. I've read on this forum replies of folks getting 4"- 6" groups at 100yds when using sabots in fully rifled barrels. Would that, to you more experienced "sabot shooters" sound corret? 6" groups at 100yds?

23" sounds like and awful lot. When I was playing shooting 12 gauge slugs at 50 yards I would guess it was closer to 6" drop. Just guessing though. I remember I could take out a soda can at 50 yards pretty easy.

sabot range and drop
 
A soda can at 50yds sounds very reasonable. I would definitely like to count on getting a clean 100yd shot out. /anymore than 100yds, well, I'm cool with letting the deer "walk". I've hunted over 45years so I don't have buck fever or anything. Just like to make a clean one shot kill without damaging bunch of meat. I wanna get my trapping license and pest removal certification, so I can possibly make some dollars eradicating coyotes and nuisance and/or predator critters within city limits area. Thank you for a reply

Think you may find that the "drop" is with a perfectly level barrel- which is rarely, if ever used. At 1450 fps, it will take about 0.103 second for the slug to travel 150 ft, right? Things fall at 32 fps, right? then that drop would be about right.

HOWEVER- the gun is not fired with the barrel perfectly level, the line of the bore is elevated above horizontal- not just for shotgun, but ANY firearm.

As long as the drop is CONSISTENT from one shot to the next, you will have a reproducible shot- and a tolerably small group. If you have zeroed sights at 50 yards, APPARENT drop would be zero.

"Things fall at 32 fps, right? "

I believe they fall about 300 fps

c3shooter 07-19-2012 11:08 AM

Hiwall- you might want to check that. 300 fps was about terminal velocity in a free fall jump, when jumper is tucked in and streamlined. Acceleration under 1 gravity is 32 ft per second/ second, or 9.81 meters/ second squared. About 384 INCHES per second.

hiwall 07-19-2012 12:39 PM

Can we both be right? It depends on how long the object has been falling. You are correct the acceleration is 32 ft/sec/sec but the terminal velocity for bullets is around 300 fps

mountainman13 07-19-2012 12:41 PM

Damn you guys just made a 50 yard shot sound like rocket science. Lol
32 fps sounds about right. To guess the water level in a well I used to drop a rock and count seconds to splash and just call it 25'/sec. Close enough for that. I don't miss well work.

robocop10mm 07-19-2012 03:18 PM

Gravity is constant. It pulls down at 32.2 feet per second per second (32.2 fps/s). Air resistance also acts on the bullet by slowing it down almost immediatly after it leaves the barrel. Terminal velocity has little or nothing to do with this. I do not even know how that became a topic of discussion. We are not talking about shooting a bullet straight up in the air.

sabots range
 
Hahaha, thanks guys, really. I understand things better at 2" drop at 50yds, 4" drop at 100yds and so on. But, i am enjoying a refresher in physics and math. Plus, it's good to get a reply from knowledgeable people, which happens on this forum alot thank goodness. This is a veryuser friendly forum 99% of the time.
