A: Thanks for reaching out Peter! In a word: yes. Any steel-cased ammunition is going to deposit more fouling in a firearm's action. This is because steel can't expand as well as brass during ignition, so it does not seal the chamber as effectively. Propellant gas residues will find their way into the action and deposit themselves there as the result. Although brass-cased ammo can fire pretty dirty in its own right, you can as a rule expect dirtier performance whenever steel cases are involved.

A: This round's bullet does have a bimetal jacket. The steel in a bimetal jacket presents a significantly higher chance of dangerous splash-back when you're firing at a steel target.
