So based on the overwhelming love for these, I take it shooting them is not so harsh like the Sub2K?
Depends, there are some hot supersonic 300blk that have some kick. The magtech 123gr fmjs are easy with a break. Subs are very soft. The sub2k was unexplainably stupid to the user. 10.5" barrel should be more gentle than my 7.5 and 8.5
