    dope for a dope

    Lapua-Bob posted a great formula to convert inches to mils so that's where I would start if I were you. Just remember not to convert inches to MOA first. Not that I'm one to be giving advice. I feel your pain though, I just switched from using a scope like that. With practice I got fast at...

    dope for a dope

    Thanks that seams pretty straight forward. I will have to give it a try. I like that it dopes in mils so I don't need to convert anything. Everything was so much simpler when everyone around me used the same system.

    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...

    M14 or 7.62mm twist rate too fast?

    Sorry in advance if I restate anything, I only skimmed this thread and thought it would be fun to reply. If you’re reading this and aren’t familiar with twist rate. 1:12 means 1 twist for every 12 inches of linear travel. So 1:6 would be twice the rate being one twist per 6 inches of travel...

    thank you for the knowledge gentlemen. the truck axle visual made me laugh. good point, I guess the brl nip trick was why I don't really care about barrel life. maybe a 28 in medium-light bl and still get a nip out of it? will a 22-250AI or the 223 WSSM with a max load push a 90 gr smk over...

    Gunsmithing lady gun.

    why do you say the 30 is useless? I guess I usually order them for the extra velocity and when the time comes I can nip an inch off both ends and add another 800 rounds (or so) to the barrel life. Am I off base? also its not a k baffle but I checked with the guy that made mine. He was so...

    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...
