Yes, sir. AIM Field Sports out of the UK has a very nice 60" bag. I have two of them, as I have a 338LM with a 34" barrel, and a 30.06 Ackley Improved with a 32" barrel. They are very quality made, and are quite roomy---I have a large NightForce on one of the rifles, and bipods---they fit quite well assembled. They have nice exterior pockets, good, strong zippers, and plastic clasps all round the outside. They have four easily adjustable retention straps inside, and molle style webbing for those retention straps to be positioned as desired.
Somewhat expensive, and there is considerable shipping, but the quality far exceeds what I have seen at shows and LGS's. Also, they have a discount for active service members.
I recommend them highly.
