Re: Gadget needed, video camera type

Brent

I took the picture of the rifle first THEN changed the position and took the picture through the scope... During the setup I screwed around with the zoom on the camera and I thought the power on the scope too.

The scope/reticle, as I understand it, is calibrated for one power (10 power, indicated by the additional "tick" mark) hence my reference to the "tick".

I therefore can use the actual laser distance and the calculated distance (assume the reticle is indicating the standard 2 MOA and 5 MOA graduations) to back calculate the power setting. I measured my shingles at 11.5 inches between horizontal "cuts" and I "measured" them against the picture at 13 MOA. ((11.5/13) = .8846) * 100 = 88.5 yards. the LASERed 52 yards / the perceived 88 yards resulting in a .59 ratio. I believe I had the scope set to 5.9 power but I could be all wet...

I'll set this thing up again tonight against a "calibrated" target and do it again.

On the height of the shingles...no method handy to tell the actual evaluated/presented height... I don't know the pitch of the roof and I'm not real well acquainted with the neighbors (city/suburban life is like that in a high turnover area).

Angle at this distance is inconsequential IMHO if shooting a decent rifle, null and void statement if shooting slingshot, archery, 38 Special, etc.

Help me out here on something I've been thinking about for a while... IYDM

The MAXIMUM error that an angle can induce (assuming no upside down weapon firing) is the total of the vertical correction at the target distance plus the "zero" distance drop correction. For example: 100 yards, scope height above bore 1.75 inches, drop from muzzle to 100 yard zero ~ 2 MOA. Rifle is ZEROed at 100 yards so total correction is 3.75 MOA to 100 yard zero. Shooter now shoots directly toward the center of the Earth from 100 yard platform so bullet [i]drop[/] is in the same plane as the trajectory. The induced 3.75 MOA of correction for the 100 yard zero now offsets the round from the intended POI by 3.75 MOA. Change target to 200 yards and add 2 MOA of elevation correction and then shooting straight down... the original 3.75 MOA is still present and we have an additional 2 MOA entered by the shooter to attempt to set the scope for 200 yards. The total POA to POI error now is 5.75 MOA and the round will strike 11.5 inches from the intended POI. SO... I guess where I headed is that if we're shooting at LARGE targets (vertically handicapped recipients like iron maidens) and we use a center mass hold we need minimal angle correction for up to about 200 yards. For targets of 8 inches or larger and distance under 100 yards we need never correct for angle... In theory.

Re: Gadget needed, video camera type

Sweat Pea (Boyd) When you can kill 3 targets in less than 3 seconds at 3 different ranges past 500 yards, bring lots of money, its time to play. Leave your bolt guns at home...Tooooo Slooooooow

By the way ....How long does it take you guys to range 3 different targets past 500 yards?

Lets see now....two spotters per target, plus the kill shot, Nine shots plus all the clickin.........Yawn.............. [img]images/icons/grin.gif[/img]
