True, these latest incarnations are pushing the boundaries forward, that’s for sure. How far they will go will be interesting to see. To my mind though, how far do they need to go?Another 25ft lbs with the heavy slugs and you end up with a rather expensive version of a .22 rimfire shooting subs. If and when they emulate that performance, they may have become rather pointless? Still, I find it interesting to see what they can achieve.
