With a few people telling about seeing coyotes in their fields, I decided this evening to dial in the T/C 22-250 to see if I can help them out. So I grabbed my target stand, target, range finder, gun and ammo for a quick sight-in session. At 50yds it took 8 shots to dial it in at 1” low. From only a bore sight I did in my gun room, I was ½” off to the right but almost 8” off being low. Then I moved the dial 60 clicks in the wrong direction but got it back and on track pretty quick. Now before I head out looking to drop something I need to get up to my club range and fine tunes her One thing I forgot about this caliber from my ground hog hunting days with my buddy in Maryland is just how loud the 22-250 is. Maybe it had a lot to do with where I was sighting in tonight or hunting the big rolling hills (flat land ) of the Maryland farms. All I know is that it’s got quiet the crack to it

Looking on line for a ballistic chart for the round I'm shooting, I came across this Winchester Ballistic Calculator on their web sight. So according to the data below, it looks as if I’d be better off sighting this round dead on at 150yrds. Basically 1” high at anything under 150yds and 3” low on anything over 225yds. I really don’t see too many shots over 150yds. I’ve had only one shot that was over 150yds. It was 218yards and I dropped him with the 280REM.

Yea that is a loud one for sure. I used to have a winchester model 70 custom shop. Gun was a shooter but with nothing around my parts to really use it on I traded it for a shotgun.
Have you looked at Nikon's spot on? Really good ballistic calculator and invaluable if you have a Nikon scope. Even with out one you can get a lot of great info and I believe there are more choices for both calibers and ammo than on the Winchester one. YOu do need java and you have to fill out some info but you can use an @whatever.com email address. I have never got any solicitations from them. Thing I like is you can print out a ballistic table (or dope as it is sometimes called) and stick it on you stock or even in you scope cap. Not super important around these parts with a 22-250 but works great with a .22 or 17hmr. I even have one for my muzzleloader.

Tom, it's always best to verify your velocity if possible before you try to read too much into ballistic tables. I've got a chronograph if you want to meet up somewhere and run a few over it.
