[QUOTE="Tripodmvr7, post: 2098460, member: 115545"] Monolithic bullets need to be lighter by 20 to 30% in weight to ensure stabilization in the normal twists of rifles. Adding tighter twist barrels helps, but you still need to look at twist calculators to see if the super long bullets will work. What I have found is that over long copper mono's tumble very easily on impact with the hide of an animal and cause serious blood shot meat. If they are unstable in flight the effect is enhanced. Rather go lighter in weight and get the speed up to ensure expansion. Penetration is hardly ever a problem with the mono's. Your ballistic app will calculate slow and fast bullets of different BC's without a problem - wind displacement will be the difficult one at range if speed drops fast due to poor BC. The newest electronic targets determine point of impact via sound and also record terminal speed. Might be easier than fiddling with the Labradar. [/QUOTE]
