And one more thing, damn right the bullet starts dropping the instant it leaves the barrel.

Not true, gravity starts pulling on it the instant it leaves the barrel, but if it is pointed upward it will continue to rise until enough force has been exerted on the bullet to change its trajectory, compared to the horizontal plane, from rising to dropping.

ok, so i will be shooting 2 guns this week. a 270 WSM with high rise mounts and a 3x9-40 burris with ballistic plex. the other is my GF's 243 with reg mounts and a cabelas 3x12-40.

so, here's a couple more for ya. i have a buddy with a 270 WSM like mine. told him to try his at 25 yd then at 100. he said it shot higher at 100 than at 25. any truth to that? had one guy say that the bullet is climbing all the way out to 100 yd. had another say that its dropping as soon as it leaves the barrel.

another is this. lets say i set my scope at 4x. get the gun where i want it. then turn it up to 9x. how much does this throw the shot off. or does it do anything at all?

The rifle shooting higher @ 100 than @ 25 is expected as the line of sight and line of the bore haven't intersected yet. Same reason one guy says the bullet it climbing and the other says it's dropping right away. Technically the dropping right away guy is right in theory. That said, your scope is 1.5" or so above the line of your barrel and what you're sighting in is the place where the bullet crosses the line, and it'll cross that line twice. Once on the way up and once on the way down. The bullet doesn't actually rise, your rifle is very slightly angled upwards so that it shoots where the 1.5" higher scope is "looking".

Adjusting the power ring on your scope should not effect point of impact, if it does, your scope needs to go in for repair. The erector tube that adjusts your point of impact and your power ring that adds or reduces magnification are two seperate mechanical processes within the scope case.

Just one more note about point of impact changing with regard to magnification. You had mentenioned that your scope is a "ballistic plex". With that in mind it is true that your point of impact as indicated by the "cross hairs" shouldn't change as you adjust your magnification, however unless your reticle is in the first focal plane, all the other aiming points will not be accurate at different magnifications.

Most hunting scopes DO NOT have their reticles in the first focal plane. If your reticle doesn't appear to change size as you adjust magnification, your reticle is in the second focal plane, and therefore the other aiming points are only valid at one magnification.

And one more thing, damn right the bullet starts dropping the instant it leaves the barrel. What could keep it away from gravity? The only reason it appears to climb is because the barrel is pointed there as related to the "line of sight". That is, imagine what is directly behind the crosshairs all the way from the rifle to the target. This is the "line of sight". So to get your bullet to meet up with the line of sight, the barrel is pointed up causing the bullet to travel through the line of sight about 25 yds down. After that it is above the line of sight. After that gravity (which has been working on it since it left the barrel) will pull it down and it will once again travel through the line of sight (at what ever range it is sighted in at).

I just usually find a rock at ABOUT 200 yards at 11:45 Friday morning. I shoot, if I hit 2 ft to the right, I just hold 2 feet to the left.

I may go out to the Casselton range this week with a video camera just to capture some good comedy.....

Unfortunately Jiffy this is all too true!! I remember when I worked at Scheel's how many rifles were bought and brought in the day before season to be bore-sited!! Sad really.

I hate the rage this time of year. Went out there last week, casleton. Kinda funny in a stupid kinda way. I was starting out with a new rifle.

BX2 your part of the rage with that new rifle.   I stay away from the range this time of year. I think most people understand the 1/4" vs clicks at 100yds.

What bothers me at the range is time wasted and lack of organization of the individuals shooting. Add that along with the pistola and ak people its nuts.

Dont forget about the Adventure shooting sports - two ranges - they keep the pistola people seperate.   I cant remember the number of tables but they have quite a few.   More organized and its amazing what a small fee does to keep the riff raff out.

horsager,
with that said, what power do you put your scope on when shooting say 200 yards? (for sighting in)

I have a very good front rest/rear sandbag setup I use for rifle league in the summer, I also use this setup for sighting in and therefore sight in on whatever the highest power setting is on the scope I'm using.

Pretty subjective question actually, just gotta shoot @ whatever magnification suits you. I've a pard who sights in his 2-7 Leupold on 2x because that's where he carries it mostly, whatever works.

If you're running high-rise (see thru?) mounts I'd start out @ 1" low @ 25yds.

Agreed, a guy's gotta find a balance between seeing the target close up vs. how much wiggling one can see through the scope. Though turning the scope down doesn't decrease the amount of wiggling, just the amount you are able to perceive.

mine aren't see through but they are a high rise. bought it at sportsmans warehouse about 4 or 5 years ago. they told me i would be better off with the taller mount since i wouldn't have to duck down as much. and since my vanguard didn't come with open sights, they said to just get the solid high rise mounts.
