Agreed. LR shooting IS good training for hunting, if only to ensure consistency with cheek weld, trigger control, breathing, range calculation, etc. All of those things matter... but LR shooting does not provide the same internal/physiological response that hunting does. Any kind of practice makes you better... but practice while hunting is a misnomer unless of course you're bird hunting, or shooting hogs from helicopters in TX
Back on topic, I have recently considered building a 6.5CM silhouette rifle, but cannot sufficiently justify it yet... I have a .308 and need to spend more time behind it before I feel like I've "grown out of it". Having more $ saved would help too...
