just got into a new caliber for myself. 22-250ai with a 1 in 9 twist
This was a good start.

Nice going!

Now how about some details as to load specifics, velocity, range of the shot & terminal performance?

Well I just purchased the handgun and took a Burris 3X9 scope off my Lone Eagle and put it on to fireform cases. Then I ran across the Burris 10X that is in the picture. I am not sure if I like the scope or not.
As far as loads for the 22-250ai this is new to me as the Competitor has a 1 in 9 twist. My 22-250 rifles are all 1 in 14. I took a box of Sierra bullets that I had and used them with 4064 powder and ended up with several 1 inch groups at 100 yards with the very first load I tried!! For me that is good enough until the soybeans get too big to see the woodchucks. After that I will see what the gun likes.

The woodchuck in the pic was in a beanfield beside my house as I pulled into the driveway. It was about a 75 yard shot. As I walked to him I found a stone axe head, local ledgend has it that my road was an indian path that followed the shoreline of lake Erie before the Great Black Swamp was drained. As a kid I used to walk the fields along the road after the farmers worked the ground in the spring and after we got the first rain to rinse off the rocks. I have found a few artifacts but it seems that the farm equipment is breaking them up.
