After reading Form’s posts I have decided that I need to get a lighter caliber practice rifle. I was settled on the Tikka 223. However, I also recently considered the Tikka 22-250. Is there a strong reason to choose the 223 over the 22-250. It will be myself and my 10 year old son practicing with the rifle. I would also like it to be an option for my son to use for deer hunting. I think they both have 1:8 twist, and I would like to be able to shoot the 77gr Tmk or something similar. Ammo for the 22-250 is easier to come by where I live. I don’t currently reload, but am strongly considering starting. Any help with my decision would be appreciated. Thanks in advance.
