    dope for a dope

    To kick things off; The wind dope math I use is: (range/100) x wind speed divided by my range constant (12) = moa wind hold My question is twofold First: is there a better way to come up with the range constant than by feel? 12 isn't quite right and it’s too expensive for me to feel out the...

    Rifle Scopes Is my scope possessed?

    I recently purchased a vortex viper PST 6.5-24x50 SFP to remedy a problem I was having with a cheaper version of the same scope. Unfortunately I’m having the same problem with this scope so now I’m stumped please help me. Just to clarify, my scope is on with the objective lens facing the...

    Rifle Scopes vortex viper question

    I purchased a viper ffp and noticed that the size of my target changes in relation to my recital sustention with different magnifications. I do not have a magnification coefficient marker on the tube like the SFPs do, so I don’t believe I got a sfp in a ffp box but it acts like one. Anyone else...

    Gunsmithing lady gun.

    I have an A bolt action that has worn out 2 22-250 barrels and a 22 CF can to match it. I am about to finish my 300 Rum build and now I need a weapon a girlfriend would enjoy shooting. It needs to be able to kill @ 400 and ring steel @ 1200. A Mile would be best but I know that’s asking a lot...

    Gunsmithing 300 rum build

    I need to order my barrel for my r 700, 300 RUM. I'm thinking a 1:9 polygonal but I want to hear some thoughts on the matter before I do. This is my one mile build and won’t see anything lighter or faster than a 220 grain VLD. Also any thoughts on a good barrel man for a poly? I already have the...

    Range Report shooting in canyon winds

    Any tricks on calculating three different wind values or even just a midrange wind? I know the speed of the wind but can’t figure out how to adjust for it when it only affects the last 600 yards of the shot. Its most of a mile away and that last little bit is making a huge difference. Everyone...

    Range Report wind call "rehab"

    I'm a former shooter trained to use range constants to calculate for wind. Problem is I'm no longer shooting a 168g sierra bthp @ 2770 fps, so all those range constants I have committed to memory are junk, I would like to figure out how to calculate new constants for different rounds at...
