If a rifle comes with a soft case from the manufacture is that adequate or should a hard case be bought for it?

Actually, it's the opposite for me.

 

I have a stack of hard cases that came with rifles, and I never use them. I have a bunch of soft cases that always get used (just bought a 52" long one to fit my long-barreled DPMS LR-208 with a big sight. So, for me, hard cases aren't so useful. I guess when I sell a rifle it will enhance the value, but that's about that.

Hard cases take up too much space. I'd probably use the hard cases if I'm doing any kind of travel beyond just going to the range for the rifles with scopes. Otherwise it's soft cases all the way. Huge space savers.

soft cases unless the travel requires the extra protection.

Guitar case. Safer for walking to the car in the neighborhood.

both. Dbl rifle hard case because I can carry 2x as much. Soft case is really convenient for a single.
