Dogs as in prairie Dogs?Not sure if this relates at all with the twist you're using with heavy bullets, but I FFed my brass in my 22/250 IMP while shooting dogs. 14TW/55Gr. You probably don't have much for targets like I did, so probably of no help. Not many dogs in Ohio....
Thank you!Congrats on getting that 22-250AI out for it's first coyote!
What were your impressions of the terminal effects?
