Most all of the Feds and the local LEO shoot those short-barreled M-4 variants.
Very few even have access to the long-range rifles and even those that do are not likely to be effective with them.
They don't train for it.
However, almost every patriot who has an AR or AK variant also has a well-tuned hunting rifle...and they know how to use it effectively. They now need to refine and extend those skills to 500yds minimum. Every patriot should be able to hit a 12inch target at 500yds, first time, every time.
Game changer.
A faithful 30-06 is quite capable of giving that range and more. In the right hands.
There are some incredible non-factory loads that can easily do that range.
Every time I think about long range accuracy, I think about Billy Dixon and the Sharps 50 in the 1850’s making a shot just short of a mile, with iron sights and black powder. THAT is amazing.
