My first post, so go easy on me, but I do have some experience on these in the east of our Island .270 and above is recommended but only recommended, think you will find its not enforced! The animal was clearly near enough for a well placed neck shot and remember the neck on a Wild Boar is bigger and less mobile than a Deer, I am sure Rim Fire would of not taken a heart & lung shot, placed correctly then a 100 grn 243 will do the job as the picture testifies. By the way I do use a larger calibre as recommended.
