how will the round impact down range at 100/200 yrds and also closer than 25?
Link Posted: 9/25/2005 4:57:20 PM EDT
all the instructors so far has taught 50yds i.b.z., at 25yds you should be shooting approx 1.5" low from p.o.a. at 50 yds p.o.a=p.o.i.
at 100yds 2-3" high, 200yds p.o.a=p.o.i. m193/m855. there is a good graph showing bullet trajectory. hope someone can post it. i'm not that computer savy. just learned this stuff recently myself....
take a class and you'll understand.

hope this helps.

The newest Marine zero is at 36m 36yds using the small aperture set to 8/3. That's really close to 35yds and will give you essentially the correct zero for the range wheel to work.

Edited to correct range

coll do i do the same steps just at 36 yrds?

Let me correct my above post:

From groups.msn.com/TheMarylandAR15ShootersSite/zeroingmethods.msnw

New Marine 300 Meter Battlesight Zero Per MCRP 3-01A (and in D. Scott Griffin's Book). Now the Marines are zeroing point of aim to point of impact at 36 yards (A2 rear sight should be set to 3). This produces a proper 300M far zero.

50/200 is probably the best method out there. 1.5" low at 25m.

I just attended a patrol rifle instructor class and we were taught a 25 yard zero. We also used the small apature which I don't understand using for close distances like we will be using it for.

if i understand this right you are supposed to switch back to the large appature after zeroing

with the ibz, is the range wheel functional? Or are they assuming that all engagements will take place within 200? I recently zereod my 16 lmt at 50 (6/3-4) and was wondering if I put it to 6/3, would it be spot on at 300...

If you follow the IBSZ the range wheel will be properly calibrated.

of course if you READ the IBSZ instructions you'd know that...

ok now iam really confused...

if ya do the zero buy the small apature.........

do you do all your shooting buy it also

what happens to the large apature? do ya not use it at all?
Link Posted: 9/27/2005 6:45:03 PM EDT
The large aperture is definitely used - for ranges of 0-200. Doing the switch as mentioned above is for your zero process.
