wascal Posted December 27, 2017 Report Share Posted December 27, 2017 The last time I was at the range we were shooting at 600yrds when the skies opened , we packed up and went home . I cant for the life of me remember if I reset the scope to 100yrds anyone got any quick tips to check where I left the scope set to? Quote Link to comment Share on other sites More sharing options...
Flyboy1950 Posted December 27, 2017 Report Share Posted December 27, 2017 Why not do a simple bore sighting? Wont be far adrift at 100 yds but much more at 600. If you have more than one rifle and they were both set to say 1" high at 100 yds the difference will be very apparent. Quote Link to comment Share on other sites More sharing options...

Oh NO !!!!!, you cant use your rifle again now because you dont know where your point of impact is going to be. Best take it to a competent rifle smith or a firearms trainer. just kidding, bore sight it. and next time remember to put it back on zero.

maxwell Posted December 27, 2017 Report Share Posted December 27, 2017 For the future buy a or make a zero stop for your scope, before that I had taken a photo on my phone as a reference due to long days on the moors can leave you off zero sometimes when dialling all day long?

walshie Posted December 28, 2017 Report Share Posted December 28, 2017 Went home because it was raining? Brave man to admit that on here. As said, bore sight it. if the crosshairs are near enough it's 100 yards. if they are way off, 600. Quote Link to comment Share on other sites More sharing options...
1066 Posted December 28, 2017 Report Share Posted December 28, 2017 I made these little "washers" a while ago just for this reason. I use them like feeler gauges to set the turret to a know zero, both elevation and windage. It's reassuring to know your going to be on the target before you lob one down range.

Vince Green Posted December 31, 2017 Report Share Posted December 31, 2017 If you shoot it at 100yds and the sights are still set for 600 yds its only going to be shooting about 6" high Quote Link to comment Share on other sites More sharing options...
Benthejockey Posted December 31, 2017 Report Share Posted December 31, 2017 ? 6 inches? We’ve all been known to stretch the truth but my 6 inches is different to yours! Had a quick play with the hornady ballistic calculator online. Shooting a 158gr bullet at 2800fps, a ballistic coefficient of .5 and 100yd zero. At 600yds your looking at 86/87 inches of drop. At 250yds you’ve got 7.5 inches of drop. Quote Link to comment Share on other sites More sharing options...

Been doing it for over 40 years, A 7.62 rifle sighted at 600 yds will print 6 3/4" high at 100yds. That's how you set up the sights on a target rifle using the zero range at Bisley.

He didn’t but I’d anticipate he’s talking about a larger calibre rather than a .22 so I took as an example a 308 load. Vince I’ll have a go at that when I get the 308 up and running. Sounds like a quick and easy trick. Although I wouldn’t have anywhere to shoot out to 600yds! Quote Link to comment Share on other sites More sharing options...

Be my guest and I hope you find it useful. - I've made them for both my 6BR and 6.5-284 for use with my standard load. It's easy, after a successful days shooting, to measure the position of the turrets with either a caliper or a stack of feeler gauges. Simple machining to part off exactly the right thickness, these were 1" aluminium. Quote Link to comment Share on other sites More sharing options...

I can arrange for you to shoot at Bisley with us as a probationary member of our club. Its perfectly legal as long as you do the requisite paperwork and can tick the appropriate boxes Edited December 31, 2017 by Vince Green Quote Link to comment Share on other sites More sharing options...

I am using a 308 this is the info / tip I'm after , As long as i know I won't go over the target , i'll just try a couple and the difference should be obvious Thanks guys Quote Link to comment Share on other sites More sharing options...

Just guessing your velocity, BC, bullet weight etc I would think you are looking more like 16" high at 100 yards. Quote Link to comment Share on other sites More sharing options...

No its not, the diffence between 25 yds and 100 yds with a 7.62 doesn't even register visibly on the target, its less than the size of the group. But even if it was 16" a target frame is a 6ft board so you would still be on the target. Work out how many clicks you would have to put on a rifle to shoot 16" high? That's more than the elevation to get out to 1200 yds. You can work it out, the elevation for 600yds is a bit less than half a degree.

1066 Posted January 2, 2018 Report Share Posted January 2, 2018 No it's not what Vince? The Bisley zero range isn't 25 yards? .. I think if you set your sights to strike 6.5 inches high at 100 yards with a 7.62 x51 the bullet would hit the ground at around 350 yards and be hitting the mantle below the target at 600 . From 100 to 600 yards you would need to come up around 16 minutes (32 or 64 clicks) This would print about 16 inches high at 100 yards. To change the sights from 100 to 1000 would be around 42 minutes. Run the figures through a calculator. Quote Link to comment Share on other sites More sharing options...
Dougy Posted January 2, 2018 Report Share Posted January 2, 2018 I've worked it out at 13.5 inches high at 100 yds 13. moa. What I find even more confusing though unfortunately, is Bisley, Iconic yet prehistoric in its running. Hope you got your zero sorted.
