thebig1 Posted November 24, 2004 Report Share Posted November 24, 2004 If the maximum distance i'm going to be shooting at a deer is approx. 50 yards and the range will only allow you to shoot no less than 100 yards, where should i be shooting on paper at 100 yards to assure pinpoint accuracy under 5 yards with my scope?

wtnhunt Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Think I would probably sight it in dead on at 100 if it was me. Should not be enough of a difference under 100 yards. Quote Link to comment Share on other sites More sharing options...
thebig1 Posted November 24, 2004 Author Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle i'm asking because i dont' want to be shooting high at 20 yards. Quote Link to comment Share on other sites More sharing options...
huntn4bucks Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Look up the ballistics for the shell that you're using. Here's the one I use for my setup: 30-06 Springfield 150 gr. Supreme Ballistic Silvertip Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Ballistics for .270 in a 150 grain core lokt sighted at 150 yards would be .3 over at 50 yards, .8 at 100 yards. If you sight it in at 100, you should be close enough to not have to worry about it. The tables do not give drop or rise under 50 yards.

snapper Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Not sure on the cal. and bullet grain your shooting...but since your bullet will rise and fall and you line of sight is straight, your bullet will cross the LOS twice. Its very posible that zeroed at 100 yards will also be zeroed at 50 yards. This post should be moved to the rifle room and with a little more info....AJ could give you the answer your looking for.

thebig1 Posted November 24, 2004 Author Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle i'll be shooting a 30-30 with a 150 gr. round. Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Think I would ask AJ on that for sure. maybe shoot him a pm. If it was like a 270 or a 30-06 I would say stick with the zero at 100 yards, but the 30-30 is not really a flat shooter and am honestly not too sure where I would sight it at.

popgun Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle My chart shows that 30-30 round nose 150 gr. soft point core-lokt is 0.5 high at 50 yards if zeroed in at 100. If zeroed at 100 it will be -2.7" at 150 yds. -8.2" at 200 yds. -17.0" at 250 yds. and -30.0" at 300 yds. all with a 24" barrel. Barrel lengths will figure into the equation as well. .....popgun Quote Link to comment Share on other sites More sharing options...
BuckNrut Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle I might sight the rifle in to be "ever so slightly low" at 100 yds. The closer you are under 50yds the less significant the drop/rise. I shoot a .54 ML sighted in at 70 yds. I know there is a 1.5" drop at 90yds and I'm 1.5" high at 50yds. At distances under 30 yds I'm right on again. Quote Link to comment Share on other sites More sharing options...
Stinger-Hunter Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle It's not enough to even give a second thought about it. Anything dead on at 100 will smoke everything from 5 yards to 95 without any adjustment. Don't over think it. Quote Link to comment Share on other sites More sharing options...
elkoholic Posted November 24, 2004 Report Share Posted November 24, 2004 Re: ? about Sighting in Rifle Unless you are trying to hit a flea at fifty yards I wouldn't give it much thought. Most rifles sighted in for a 100 yard zero, using a scope with the cross hairs 1 inch above the center of the bore, results in the bullet crossing the line of sight at approximately 25 yards and the mid range trajectory is approximately 1/2 inch above the line of sight. A very large scope or a see through mount may result in a different scenario (bullet may first cross line of sight at 100 yards) but I doubt the deer will feel the difference.

elkoholic Posted November 25, 2004 Report Share Posted November 25, 2004 Re: ? about Sighting in Rifle Snapper, while I'm not sure as I have not tested it but sinse most rifles have a trajectory that rises and falls less than a couple of inches out to 100 yards I would think any setup with the crosshairs more than 2 inches above the center of the bore would result in the bullet not crossing the line of site before reaching 100 yards. Never really thought much about it before but now I wonder if anyone knows of any testing done along these lines or if they have experimented themselves. Again, I doubt the deer would feel the difference either way. One thing I do know is that there are hunters who use the dead on at 25 yards is dead on at 100 yard theory and that does not work in all instances.
