I don't know that I would ever shoot over 100 grain as the Barnes would actually retain more weight than heavier lead core bullet but the added length of the monolithic bullet has me thinking and a faster twist certainly won't hurt a thing. As to the AI versions of cartridges, Boots you have that 250 AI in my head as a possibility in the future. Did a little research and that is an impressive little cartridge. Be a good one for the daughter.
