thx for the great reply nomercy but.....i want to know how much of a role wind plays at those long distances since in my area there r many open fields and i want to be able to hit yotes out to 400-450yards.

is there any website i can goto to see charts of wind affects on factory loads?

say if i get a .22-250 i can shoot 40gr - 55gr factory loads right.....
but if i get a .243 i can get 55gr - 100 or sumthing....

i will probly never use it for deer (no rifle hunts in this area, got rifled shotugn barrel for that) and if i do go north where u can use a rifle i have a .303 for moose, bear, deer, etc.

so which would be better? the .243 where i can get 55gr? or .22-250 with 40gr?

so overall would the .243 with 55gr or 75gr ballistic tips be better or the .22-250 with 40gr or 55gr be better?

i want to be super sure i get the right one since im ordering from alberta so its not as easy to return, plus it take a long time to get back.

please remember i will be frequntly be making shots at 250 - 425yards.

thx
