Re: Question - how many guys use their mildots as hold-over points?

Ian, i just went out today to test some loads out of my 16" XP 6.5-284 to 800 yds. Unfortunately i haven't found a bullet that shoots good yet out of the rig, although the 129 SST seems to be the best so far. I've got a 3-12 Burris LER with Ballistic Plex reticle/target turret. I've been doing some calculations with it to determine the best way to use a tactical system while hunting. Here's what i've come up with. i've established the minimum magnification i need to set the scope at for MPBR between the upper post and x-hair using ratio and proportion formulas once i know 100 yd. reticle subtension(for my load and a 19" steel target it comes to 6.6X-- kind of hard to find actually on the power ring, but my "guess" has been fairly close so far). I use this minimum magnification system for hunting conditions since the eye relief on that scope @ 12X is pretty critical. I then calculate the 6.6X zero's for the ballistic lines with Exbal. I then run another zero system for 12X. If it's not close to 50 or 100 yd. increments, i simply apply the power optimization option that Gerald has on the program to "fine tune" the reticle zero's @ a different magnification. All this info. and windage holdoffs is noted on a sticker and placed on my scope ocular (the simplest reference system that i've devised for my needs so far). Now here's the interesting part. Instead of running clicks for distances beyond the lower post zero, i've been trying to use the power optimization option to establish additional 50 yd. zero's to 800 yds. But so far i've found this system isn't as easy as running clicks. I tell you though, Exbal is just the most valuable long-range resource i have--- not that this all has much to do with mil-dots, but i think holdovers/calculations (especially relative subtension changes with magnification changes) would probably be similar.

Re: Question - how many guys use their mildots as hold-over points?

I am more comfortable holding under than over. I zero at 100 yds and add come-ups (17 moa) so that 5 mils under coincides with 100 yd impact. I calculated the holds using a simple calculator, being careful not to get confused between 3.438 moa and 3.6" per 100 yds for each mil, then verified through actual firing. My load for my last barrel put the 190gr SMK on the crosshairs at 775 yds using this method. Farther than that I get on the el turret.
Rapid fire is the crutch of an incompetent marksman. ONE SHOT, ONE KILL

Re: Question - how many guys use their mildots as hold-over points?

Ian, the math is pretty easy on the B&L. The mil dots are calibrated for 12x so they are half mils at 24x. The NXS I have is a 8-32x, so I just use the R2 at 22x most of the time. But I have it calculated for 10x, and 32x as well. 10x works real well for multiple target engagements at ranges under 1000 yards. With the marks at just over every 4 moa at 10x you can dial almost any range in with the use of a mark for major elevation and just a couple of clicks in either direction to fine tune.
Working to improve hit probability.

I use holdovers, in MILS. Zero at 100 / 300 yards, then hold off of my mils from then on. Check out Lou Schwiebert's "Ballisticards". He makes beautiful, laminated cards specifically for your load, bullet velocity and bullet BC. You will like them alot. The cards have a column for MOA, MILS and inches of drop based on your data and elevation that you are shooting at. I am not sure, but I think that a Fed Agency purchsed 5,000 of these. Also, there are some Great software packages out there that do run on PDA's if you are willing to spend $300.00 and up.

I used the hold over system when I went to Africa this summer. I used an IOR 2.5-10x42 MP-8. I taped a chart to the objestive bell houseing. I shot cridders form 30 yards on an impala to 425 yards on a red hartebeest. It really worked well. Quick and accurate enough for kill shots everytime. 8 animals in all.

Re: Question - how many guys use their mildots as hold-over points?

I use a 4.5-14x50 Premier tactical on my custom 22Lr shooting subsonic ammo, I zero at 70 metres and 5mils gets me out to 150m. Just last weekend I shot 3 rabbits for 4 shots between 145-150m hold off was 1 1/2 mils for the wind, the rabbit I missed with the first shot was lying down trying to imitate a log.
For my type of shooting the only thing better than a mildot would be a Gen-2 mildot so that I can use the hold overs on any power.
I have a table taped to the side of the stock with holds from 10m out to 220m (10 mils).
