two bags
I have two bags, one for rimfire and one for centerfire, whether rifle or handgun. The centerfire bag is an LLBean shotgunners range bag, they have two sizes to choose from. The rimfire bag is a S&W bag I received from S&W for having bought something from them, has end zippered pockets with big center section, does good.
But a tool bag can do the job.
Also, LLBean has canvas boat bags with zippered tops to them, they are practically indestructible.
