About the best thing I've found is plastic pellets used for blow molding. About the same size and shape as rice, but won't split the seems on your bag if they get wet.

Hey Jeff, you have a max rifle distance for us?
-
Here are some unofficial overall numbers with all divisions together using just a simple sort by Total Time not stage percentages. Interesting to see how well the 1x guys did vs. the optics guys. Unfortunately the rim fire guys had a much tougher long range so they didn't climb up the results list like one would expect.
I like this method much better, moved me up the list.

Fun match, just barley got to attend as my boss is an ahole. Squad 5 was a hoot to shoot with enjoyed everyone. Special thanks to the Nordic guys for their support.
Shooting those pos cube things will be fun with a shotgun!!

With a DPMS 1 in 10 twist 20" barrel, pushing a 155 SMK (2155) @ 2850 fps using 45.0 gr. Reloader 15, LC brass. Use 43.5 gr. IMR 8208 in LC brass for bolt rifle, sends a 155 Scenar @ 2900 out of a 24" barrel, damn near 3000 out of a 30".
Tried 175 SMK, both 155 SMK's, and the 155 Lapua, the 155 SMK (2155) consistently shot the best groups out of my rifle out to 800 yd.

I'm a FFP fan but I haven't seen an advantage in 3 gun comps. Works great for unknown distance steel matches and bolt gun comps. In 3 gun comps you want a scope that is fast on the close stuff (1X bright red dot big enough to pick up quickly) and when the power is turned up gives you a reticle that can be used for hold overs out to 500 yd. (used to be 300 yd. but keeps getting stretched out). This implies a second focal plane scope where the reticle doesn't shrink or grow depending on power setting. As with all things shooting it has more to do with the shooter than the equipment.
-
Of the 3 you listed the Burris is the most bang for the buck, you can save on the mount by getting an Armalite mount for around $80.00. You might consider a used Meopta K-dot, I ran one for years and still consider it a top 3 gun optic.
What ever you end up with, put in the time to learn the reticle with the load your going to use. Hitting the targets is the main objective, but hitting them quickly gets you points.
-
Your asking a reticle to do an awful lot. Granted it would be nice to have a reticle that will take all the thought out of aiming, but until you can control the wind and other atmospheric conditions your stuck having to adjust for them. The beauty of the standard mil or moa reticle is that the hash marks are equal, your not stuck with one bullet choice or velocity.
Look at a typical long range rifle stage that you might see at any major match. You will have maybe 8 to 10 targets from contact to 400 yds. If your zeroed at 200 yd. then there is very little elevation change needed to hit a 8" plate out to 250 yd., hold center mass and it hits. At 300 yd. with my load (69 SMK @ 2750) it is .8 mil hold over, so just hold first mil. dot under cross hair in bottom 1/3 of plate and you have a hit, at 350 it is 1.3 mil hold over, just move first dot up to top of plate and another hit (at 300 yd. a 10" plate just fills the space between the mil marks). Move to 400 yd. and hold over is 1.8 mils, put 2nd. mil mark in bottom 1/3 of the plate and you get another hit. OK so we have shot all the targets out to 4ooyd. and we haven't even used 1/2 of the reticle yet. With minimal practice these holds become automatic. Plus you can pull the scope off the .223 and put it on a .308 and the reticle is still good to go.

Below is the printout of my 3 gun load out to 600 yd. Fifth column from the left is Bullet path which shows come ups using a mil based reticle. AS you can see I've used a 200 yd. zero (1st column is distance to target scan to 5th. column and you see zero elevation required). Now go down to 500 yd. line and you'll see 2.99 mils of elevation are needed to hit the target. Use the third stadia line below the cross hair and it should hit (if you have doped the wind correctly).
The ballistic program handles all the math, all you have to do is remember the holds for the different ranges.
You can do the same with a moa based reticle, just a different value for the stadia lines.
1 mil = 3.6" @ 100 yd. or 36" @ 1000 yd.
1 moa = 1.04" @ 100 yd. or 10.4" @ 1000 yd. Most of the moa based turrets and reticles are actually set up in what has become known as IPHY (inch per hundred yards)which would yield a 10" value @ 1000 yd.
There are several ballistic programs available on the internet, JBM and Nightforce to name two. Your most important inputs are:
velocity of bullet
BC of bullet (can be found from manufacturer)
zero distance
height of scope above bore line
elevation where shooting
and to a lesser extent atmoshere conditions.
Hope this helps!

Do you guys shoot a specific weight bullett to make it match up with the reticle or is there some way to allow it to adjust for any weight bullett. I am very new to the rifle shooting trying to figure it all out, ballistic programs, and reticles.. It really can make your head spin with you are starting out
Reticle will work with any bullet at any velocity, just plug in your specific load to any mil based ballistic program and you will be close.
-
Any decent ballistic program will work with this reticle, doesn't have to be Swaro's. Just use the mil setting for elevation. Windage as I understand it is preset for max of 20 mph full value wind. Only problem with that is, what bullet at what speed and bc did they use for the calculation. If anyone knows the value of the hash marks on the windage part of the reticle, I'd like to have them so leads could be figured for movers.
Mounted mine up yesterday and set zero at 200 yd., used my standard ballistic program for come ups and hit 8" plates out to 400 with printout holds. Wonder why it has taken 10 years for this simple solution to come along?
-
I like steel for anything past 300 yd. You can see your hits on a fresh painted target to at least 1000 yd. Doesn't require as many trips down range and then all that needs to be done is paint your hits. Have found 1/2 IPSC fine to 500, after that I like to have a full IPSC along with a smaller target for those windy days that give us all fits.

A lot of things affect seeing trace, weather, caliber, quality of optics, position, lighting, etc. Spent most of the afternoon yesterday either shooting or spotting, conditions changed during the time we were out, from around 1pm to 5pm. Midday can be a tough time because the light is "flat" not a lot of contrast. We were shooting from SE to NW and as the sun's angle changed the "seeing" got better during the afternoon. At one point around 4:30 while shooting at 600yd. you could pick up the bullet as it neared the target. Not real common but I've seen it several times.
When setting up I try and get as square behind the rifle as possible, usually stand so I'm above the trail early in the bullet flight so it doesn't cloud my view. Don't concentrate on the target, look above and if windy to which ever side the shooter is holding wind. Try and visualize the bullet path and pick it up mid flight so you can watch it into the target. 20 to 25 power is plenty even to a 1000. Real windy days the trace dissipates so quick it is really hard to pick up, around a 10 mph wind will move the trace enough that you have to compensate your call for the changes. With .223 and 6mm I can see my own trace through the rifle scope, about half the time with 308 if shooting at 500 or better. Like most of the stuff shooters deal with, it just takes practice.

I'll dust off the cobwebs and dash a little oil on the ol SX 2 and see what happens. If you need me to work should be able to.

I don't even worry about spin-drift at 1000m. Im lucky enough that we have a 1000m range about 5 miles from where I live, so I do get to shoot it as often as I like. Your main concern sould be with making sure that your scope is level with the rifle. also, inslall a bubble level on the scope. You'll be amazed at how crooked the world realy is with a bubble level.
Good advice, take it.

Well this is good news, if it rains I'll be down, maybe even if it doesn't.

Stages being designed and built by some NOTEABLE 3-gunners (Miller, Swanson, Cramblit, KEEN ) .
OK, so I've heard of this Keen fellow, who are these other posers.

Greg, I applaud your hard work and willingness to put on a match. I've "played in this arena" for quite some time and I have a feel for what works and what doesn't. Just hate to see another shooting sport ruined by NRA.
Just to clarify, I'm a life member, certified instructor, and F-class participant with the NRA.

The last thing I want to be is a lawyer!
Have no desire for the court experience.
All games have rules and before we play we need to know these rules. Having read the rules before sending in said money I fulfilled my obligation to protect myself from a bad experience due to funky rules.
Lets see how this would work with other sports.
NASCAR
You show up to run the standard counterclockwise (left turn) race and they say we think it would be fun to run clockwise (right turn), think that would fly.
Football
To now score a touchdown you have to cross the line only between the goal posts.
Baseball
For a home run you have to hit the ball over a 50 ft. section of the centerfield.
All this after you have paid entrance fee's, travel expenses, and numerous practice sessions.
-
Man, be gone for a couple weeks and a match changes the rules after my money is in. Don't care for the changes. Breach of contract anyone? Excessive doesn't even start to describe this scoring farce.
The NRA is fair at what it does on the political stuff, but it has screwed every shooting sport it has ever touched. Hope this isn't a sign of things to come.
PM sent.

I carry an AR pistol in the tractor, combine, and pickup almost always. Several coyotes, skunks, dillo's and badgers have been dispatched with this setup. Most equipment now have very nice cabs, AC filtered air, tight seals so dust is not a problem.
I've got a friend that wants a .204 AR, have tried to discourage him but not sure if he see's the light yet. Load up some 40 gr. ballistic tips and let him try those, might help convince him the .223 is the way to go.

If you know what button to push it's free!

I thought the Europeans were supposed to be more refined and well mannered, guess not!

As long as Mel isn't there you don't have to worry about running out of drinking supplies.
Which McMillan
in Precision Rifle
Posted
This is the ticket. My first custom stock was a McMillan, the last 3 have all been Manners with the mini-chassis. Bolt the action in, mount the scope, go shoot. The last one I put together from the time I unboxed it to first shot was under an hour.
