    Rifle Scopes Exit Pupil Reality

    Re: Exit Pupil Reality <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: CoryT</div><div class="ubbcode-body">I'm not sure what the actual issue is, since the eye is at maximum about 7mm, so an exit pupil larger than that has basically no effect on anything anyway...

    Remington 5R MilSpec twist

    Re: Remington 5R MilSpec twist Captain, why don't you call/write remington and tell us? As for myself, and with due respect, you measuring system is not really foolproof. And I cannot think that some other data points from people that have no specialized equipment (or that can make humand...

    Advanced Marksmanship Speed reload with a 1911

    Re: Speed reload with a 1911 Totally agree with CoryT... Shooting games are great for honing skills, but when you start counting rounds and choreograph your every move, change mags or not for no logical reason other than the game rules, and disable things like slide stops to be more...

    Advanced Marksmanship Speed reload with a 1911

    Re: Speed reload with a 1911 Some IPSC shooters disable the slide stop to avoid an accidental lockback (for some reason, including hasty manipulations, it may happen) while there are rounds still in the mag. Since movements are choreographed you normally don't shoot it dry. It has nothing to...

    Remington 5R MilSpec twist

    Re: Remington 5R MilSpec twist Same barrel blanks (with different external profiling), urban legend or not, it is VERY expensive to make mandrels for cold hammer forging, and since remington already has the specs for the M24 barrel I cannot think why they would pick anything different fot the...

    Rifle Scopes Exit Pupil Reality

    Re: Exit Pupil Reality At high magnification generally the exit pupil is: objective diameter / magnification At the lower end this is rarely true, because there are many other design constrains that limit exit pupil. Many manufacturers just "round up" numbers, for example the NXS 3.5-15 is...

    Remington 5R MilSpec twist

    Re: Remington 5R MilSpec twist Since these barrels are manufactured by cold hammer forging ALL of them have the same twist, there is no room for twist variations with this process...

    7.62 NATO vs .308 Is there a Difference?

    Re: 7.62 NATO vs .308 Is there a Difference? There is a lot of bullshit on the net, and many articles claiming that safety wise the difference between 308/7.62N is as significant as 223/5.56. But SAAMI does not put the 308/7.62N in the "dangerous combination list", and does it with 223/5.56...

    Re: FN SPR A1a Benjamin, are the 10 round magazines available now? Will a kit be available to retrofit SPRs with the current DBM bottom to the new one that takes the 10 round mags? TIA

    Rifle Scopes Review: March-F 3-24 x 42 FFP

    Re: Review: March-F 3-24 x 42 FFP Heavy is related to strength against impacts... that's why mil scopes are heavy. For a range gun you could get the same durability with less weight, only worrying about Gs when shooting. For a mil scope you would want more objective diameter to effectively...

    New 2 Mile 50 cal bullet?

    Re: New 2 Mile 50 cal bullet? I would be scared to shoot that thing... looks WAY more than 1000 grains and with a lot of bearing surface.

    Re: why the 155gr. scenar for .308 squarenut, if you use the Miller formula you will see that gyroscopic stability changes VERY little with +/- 100 fps... http://accurateshooter.net/Blog/millerformula.xls

    Range Report why the 155gr. scenar for .308

    Re: why the 155gr. scenar for .308 Form factor was traditionally used the other way around: a theoretical form factor was calculated from the geometrical properties of the bullet, and then BC was defined as the sectional density of the bullet divided by the form factor. But to get correct BC...

    Sandia new laser guided bullet

    Re: Sandia new laser guided bullet This is clearly waaay too early to tell... Currently our known technologiy with non guided bullets is king of the hill, but remember how "safe" was the typewriter when the personal computer was born, or kodak when the digital pictures started.

    Rifle Scopes New from March

    Re: New from March quote=Ian A. Kelbly]Guys, The reason we have the .05 MIL clicks is for super long range shooting. The .1 MIL clicks past 800 yards tends to miss small targets. To be highly accurate at long range, you need small increments in adjustment without using holdoffs. -Ian Kelbly...
