Will the SMKs shoot good in a rifle that has alot of freebore, as in a factory weatherby? I have a 340 weatherby that shoots barnes ttsx 210s very well. I am trying to find a higher bc in around the 250 grain that have more expansion than the barnes. Tried berger 250 otm, never did get them to group better than a shotgun. Is there any thing with good bc and expansion that will work with the free bore of the weatherby? Thanks for your help.
