for my bench rifle I have a hard case. It won't fit in a soft case, and that said some hard cases might be tight, but it has a folding stock that gets folded in the hard case.
Can Tire has them go on sale often, and they work great. Carry my bolt separately, mags, bipod. The huntshield with rollers on the bottom. Can get 2 rifles in there if done right with folding stocks.
My other 223 range use rifle doesn't fit in any soft cases either, so a cheaper double rifle case it travels in. Most of the others go in soft cases to the range, as they fit in them.
I take 2-3 trips from the vehicle to bench at the range to carry everything. Almost never go with one rifle. I say almost as the only time is a quick trip to finalize a new load, or load development, and that is quickly in the evenings before dark.
