I've shot/got 7-08's from 14"(XP-100) to 26" and would never go more than 22" on purpose,nor less than 20"(noise). The exception being a platform expressly geared towards running a can and then I'd go 18",to keep overall length handy-ish.
162 ELD's at 2700fps,leave an impression in all zipcodes and REALLY carries the Mail.
SAAMI throating will mandate binderless AICS mags,to reap a Smooch,but that is a nice way to do bidness and is a great leap over suffering Wyatt or similar.
Favorite Sleeper...for Lippy Dissenters. On the bottom.
With a 200yd zero,162 ELD's in the mag,20" spout and 2550fps low PSI Launch(due primary and secondary extraction penchants in the lever gun),the windshield alone will get it to the Ten Hundo yardline. Parcel retains 21 Mils on the erector which is the the 1475yd line in this morning's atmosphere(6x MQ) and all in,will punish the 1775yd line.
Dissenters HATE it...............(grin)
