I am trying to figure out the useful range of a 995 carbine when you can only set it once and not touch it again, and where to zero it at to get the most effective use out of it.
Using a watered-down online calculator (many external values set to 0 or otherwise standard values), I found that with the sights zeroed at 100yds, a 115gr bullet at 1200ft/s MV will be 5" low at 125 yards and 12" low at 150 yards. Its max height above LOS will be around 3.2" at 66yds, which is quite reasonable especially for a Red-Dot sight.
I found this to be the most logical zero point. Zeroing at 75 yards only saves you about 1.5" as far as bullet-rise goes, but you lose about 5" at 150 yards, so I don't think the trade-off is worth it. Also, velocity drops to about 925ft/s by 150 yards so beyond that you might find some penetration issues if you tried to zero it any further than 100 with hopes of getting some more range.
My question to you guys is simply if this sounds accurate?
Also, how do those muzzle velocities sound for standard ammo?
Hopefully I can get into reloading sometime this summer and get those velocities up around 1500ft/s, then 175 yards would still be quite realistic (11" drop, zeroed at 125 yards), hehe.
