    Rifle Scopes how much elevation does 1/2" height delta at scope translate to at 100 yards?

    1/2" taller rings will only buy you 1/2" at 100 yards. Sounds to me like the bedding job has gone bad making it a virtual 50MOA base.

    Rifle Scopes Suggestions for high quality 34mm Rings

    It is fine to put steal rings on an aluminum base. Einstein is not as smart as he thinks he is. I use the Badger USMC rings on an aluminum rail and a S&B PMII 34mm tube. Very sturdy setup.

    Rifle Scopes Need Help Setting Up S&B PMII Scope

    I think S&B justs wants to be ready for the 40MOA and higher bases. Better your first shot be low. I set mine like they said, shot paper at 50m and calculated the mrad adjustment to zero. Second shot was close enough to move to 100m for final zero. Then I reset the DT turret to zero.

    Rifle Scopes 20 MOA Base 100yd -> 500yd help

    Maybe you could use a visual analogy using a flashlight and a garden hose. Think of your barrel as a garden hose. Consider your bullet path as the water squirting from the end. Think of your scope as a flashlight Consider your scope adjustment area as the beam of the flashlight. If you...

    Rifle Scopes My Vortex 6x24x50 PST... You fellows need to know..

    I have a 6-24 pst on a .300 mag with a brake. Savage 110BA. The last time I was out shooting the POI drifted 3MOA withing 5 rounds of match ammo. I was so sick about it, I put it up and have not shot it since and that was 3 months ago. Looks like I need to sell the PST after it gets back from...

    Bye Bye Bi-pod, Hello Mega-Benchbag!!!

    I my opinion as a scientist, the only way to develop loads is to take all other variables out of the equation or as many as possible. Like shooter, wind, temp. I would use a lead sled and shoot indoors and probably rig up a camera for the scope and a servo for the trigger. Once you get the best...

    Semi-Auto Groups and Range Reports

    "what they could reasonably expect from a gas gun" This is more luck than typical for a semi auto 308 shooting factory ammo. Shoot 6 5-shot groups and avg to get the MOA of the system. Removes luck from the picture. Enter it in Elf's 300yd shootout and you will win top prize, or get shamed for...

    RRA LAR-8 Any advice?

    I took about 1/8" off that adjustable cheek part to let the charging handle come all the way back when the cheek piece was up in position. I also put a charge handle side pull on. I believe it was from Badger. The PRS was the model made for the AR10.

    RRA LAR-8 Any advice?

    I only looked at RRA for different rails. They had what I wanted so I didn't look aftermarket. This is using each GMM at 109yd. That first rnd was a little crazy.

    RRA LAR-8 Any advice?

    I have the 26 varmint and have 6 fal inch and 6 RRA poly mags. The poly mags are not tight, but they don't gravity drop out. Someone on here recommended an area to remove some material on them but I have not tried it. The FAL inch mags work fine. When new, my chamber was about .0005" too...

    CQC 25/50/75/100yard, 20round only, iron / red-dot / 6xMAX only, king of the hill SHOOTOUT

    Looks like fun, but the only semi auto guns I have with iron sights or red dots are 9mm, 45, and 22 pistols. Darn! How about if I turned my S&B scope down to 5X? You should start one of these for the 45 sidearm and go 7yd, 15yd, 25yd, and 50yd.

    **ROUND2 !!**, (100YARD), Semi-Auto, 6group, 30round SHOOTOUT!

    Do you think you might have hit a bug on the way to the target? I have always wondered what effect a nat, misquito, bee, june bug, or cicada would have on a small light round like the .223.

    (300YARD), Semi-Auto, 6groups, 30round SHOOTOUT!

    It looks like your groups are smaller than you think. Did you subtract your bullet diameter? It looks like your dial is on 2.972 at the outside to outside. Also, where is your rifle pic? I would like to check it out. I want to do this with my Rock River Varmint LAR-8 26 bull. Looks like fun!

    Rifle Scopes Ran out of windage sighting in scope

    I do not bore sight so I am unfamilar with how far that process can be off, but the group scattering sometimes could be your rifle looses level between shots and with the POA 17" from the POI, a slight tilt would result in way different POI. Turning the base 180 is not proff it is good. If...

    Rifle Scopes Ran out of windage sighting in scope

    Woops, sorry. I figured a 77 was a 77, Mine is 22-250. Sounds like you have a good debug plan. My Vortex Viper looks a lot different than yours. What is your full adjustment range of windage on that one? Elevation wise, when I set up a new scope/rifle combo, I try to get a canted base...

    Rifle Scopes mils vrs. moa for scopes??

    I like reading these MIL vs MOA threads. I have always been into precision and physics and hated to see the way people would mis-understand the angle and substended parts. I like the way some keep beating it into peoples head about the subtile differences between the MIL and MOA. I tried to do...

    Rifle Scopes Vortex PST vs. Leupold Mk 4.

    I got the Vortex Viper 6-24-50 Mrad a month ago for my Savage 110BA. My first impression was awesome clicks on the turrets and excellent zero line up. The brass shims seemed a little cheezy for an approx zero stop. Still, serves the purpose. My biggest complaint is the 100M focus at 24 power. I...

    Rifle Scopes mil or moa

    One of the red dot optics leaders Ultradot sent a manual with my Matchdot that states "1MOA clicks at 100y and 1/2 MOA clicks at 50y. When I emailed tech support to let them know about the mistake, they were convinced it was not a mistake. I argued with them till they would no londer even reply...
