Rifle Scopes What magnification do you use when shooting at 100 yds strictly for group size?

What mag. are yall using when you shoot test loads for groups at 100 off bags? I am using 12-15x. I am just trying to find out if I am over magnifying.

I use 20X, some times as low as 15X when shooting for 5 shot groups at 100 yards. Any more than that and mirage gets to bad.
 
I used 14x on my last range trip. I have a sheet of 1 inch squares that I post at 100 yards, then I zoom in the magnification to make the square a decent size, however big that might be. For load development, I line the bottom edge and the right edge of the square up with the -x and y coordinate of my reticule. The goal is to get the two edges of the square to touch the two lines of the cross hairs, essentially aiming at the bottom right corner of the black square. I have also found that using less magnification can also be helpful, as more magnification will sometimes cause a shooter to fuss the shot more.
 
I agree, when shooting precision, I use the most maginifcation I possibly can before mirage becomes an issue. On my bolt gun, that would be 42x, with my AR, 16x.

I crank up the magnification as high as I can if I'm just shooting for groups. About the only thing that would cause me to back off from maximum magnification would be mirage from barrel heat.
 
+1 on the higher magnification. Except for mirage as mentioned I'm not sure there is such a thing as over magnifying.
 
Was shooting at 100 and 150 today.
Ran my XRS at 30x until the barrel heated up and mirage got annoying, then backed it down until it was less annoying, maybe 20x or so.

OK Great. I guess the concensus is Im not turning it up enough. I will try that this weekend. Thanks so much for the input.

I use between 8-10. I find too much magnification makes it more difficult to hold the reticle steady.

+1 i use nxs. put it bet 10-12 that makes it 11 i guess..the higher you go the more on sensitiity on cross hair...BUT ill try 22x next time :)
 
42X for bug holes at 100yrds in the early morning. 600 yards @ 20X for load load testing because 100 is too close IMHO for "the" most accurate load for a given High Power rifle.
 
well, depends on which gun, but i max it out. the .308 gets 20x, the ar's get 14x and the 40xrf gets 32x
 
Hola buenas noches y me presento, soy Agus del sur de España.
Un honor y placer poder meterme por aquí aunque no hable apenas inglés americano, ninguno en verdad que no sea el mío.

Soy partidario de poner el aumento al mínimo siempre que pueda ver con claridad el MOA y poder dividirlo con 4 porciones de pizza de 90º. También está claro que depende del tipo de retícula. Por ejemplo, en la retícula EBR-7C de mi Vortex imposible de afinar con el mínimo de 5X. Casi en 10x me quedo.

Por otro lado en la Smichdt & Bender PM 3-12x50 del AW me permite un buen zero con 4x a 100m retícula Mil-Dot.

Pero siempre el mínimo posible. Apunta a un botón de la camisa por ejemplo no al pecho.
Bajo aumento, visión pequeña en caso de error humano será pequeño.
Aumento grande, objetivo grande y posible error grande.

Funny,his post is on topic.
It must mean he is using his browser to translate.
Why didn't it translate back the other way ?
Obviously he's saying he uses a S&B PM3 set at 4x for 100 meter groups and says (with my shit spanish) that using a larger objective results in larger errors ????
I really hope I got that wrong because I have big scopes and little ones and have never seen any difference regarding objective size.

Your Spanish probably isn’t any worse than Apple’s. But, I think he’s saying that high magnification magnifies aiming errors. This, however, I don’t think is correct. Low magnification just prevents you from seeing the errors you are making…
 
Gracioso, su publicación es sobre el tema.

¿Por qué no se tradujo al revés?
Obviamente, está diciendo que usa un S&B PM3 configurado en 4x para grupos de 100 metros y dice (con mi español de mierda) que usar un objetivo más grande da como resultado errores más grandes.
Realmente espero haberme equivocado porque tengo visores grandes y pequeños y nunca he visto ninguna diferencia con respecto al tamaño del objetivo.
Perdón por la traducción, por ser nuevo y comenzar por aquí.

Pienso que poder utilizar la menor magnificación posible, menor movimiento óptico, mejor agrupación. También mas exigente para el tirador.

¿Apuntas al pecho de un hombre? No, apunta al botón de la camisa que lleva ese hombre.

Cuando no comienzo a percibir con seguridad de buena parada en el centro del moa aumento magnificación.

If your scope is moving under high magnification, it is also moving under low magnification. You just can’t see the movement because of the low magnification.

To expand on the button versus shirt, a thread hole in the button provides a much more precise point of aim. But, you won’t see it without more magnification.

I have scopes with as much as 25x magnification. While I rarely use more than 12-15x for long distance shooting, I’m at maximum magnification for short range precision shooting. To that point, you can be assured I’m at 25x with a 22 long rifle at 25 yards.
 
Si su telescopio se mueve con un aumento alto, también se mueve con un aumento bajo. Simplemente no puedes ver el movimiento debido a la baja ampliación.

Para expandir el botón versus la camisa, un agujero de hilo en el botón proporciona un punto de puntería mucho más preciso. Pero, no lo verás sin más aumento.

Tengo visores con un aumento de hasta 25x. Si bien rara vez uso más de 12-15x para disparos de larga distancia, utilizo el aumento máximo para disparos de precisión de corto alcance. Hasta ese momento, puede estar seguro de que estoy en 25x con un rifle largo 22 a 25 yardas.
También suena lógico en parte... Lo probaré en breve.
 
I use 6X or 10X fixed, cause these are hunting rifles (22LR - 300WM). I use a 1/2" red dot sticker as my target. Easy to shoot sub-MOA with either at 100 yards.
 
20-25x and higher dry firing will help you understand what impact your heart beat, breaths and trigger pull among other things have on precision.
 
For load development, even at 100 yards . I always take the golden eagle. For me it’s easier to focus on trigger control when the target appears as close as possible. Usually around 50x with a nice fine crosshair. That being said the recticle for me plays a huge role as well.
I also use a Rock BR in the front and a huge Protektor 4” long rabbit ear in the rear.
 
My groups are tighter when I can see the fibers in the target paper. 25-30x most of the time.
 
I find this to be a strange question to ask. It all depends on your scope and reticle, first / second focal plane, floating dot / cross hairs only, thickness of the reticle and so on…..
 
I mean, if we’re intent on resurrecting this thread... I find it just doesn’t matter. I’ve shot with 12x because that’s what I had, 4x because that’s what I had, 24x becaus that’s what I had, 16-18x because I wanted an “eye box” that didn’t suck, etc.

You’re stable on the gun or you’re not. Visual feedback is one way to get that information, but it’s a double edged sword if you’re allowing visual stimuli to degrade your trigger break. As long as you can make out a crisp POA on the target appropriate for your sights, you’re good.
