Ok, I go along with pretty much everything above on the Wildcat, but I'm still struggling to find anything much smaller; as good or better, and then of course there is the price, how much are you prepared to pay for fractions.
At the moment I still run the Wildcats on all my centrefires, .223, .243 and .308 but mine are all the COMPACT version and go some way to address the size and weight issues. I have posted this pic a few times when this question arises, but maybe helpful. The tube near the top right is the full length tube and gives some idea how much shorter the Compact version
