I have a .243 for foxing & deer, and subsequently use lighter 55gn silvertips for most of my foxing and heavier (100gn) for my fallow/reds... I met a guy recently who's a pro, and said don't go below 80gn as the light stuff will burn your barrel out very quickly. Does anyone know if this is true?
Presumably the velocity is higher as it's a lighter round, but surely the weight doesn't make that much difference to barrel wear?!
