I have a 260 with a 25.5" barrel in a McM A-5 stock, 1.5" of buttplate spacers and AMG on a 20moa base with NF UL 1.0" rings. Fit is great with 1" of foam behind the butt and 3.25" past the muzzle. Space for 6 magazines, sling, bipod, can bolt and cleaning rod. There's a big empty space I want to put a cleaning kit in, just haven't gotten around to it. Pretty sure the 300wm RWS is building for me with a T4A and 26" barrel will also fit, but I will probably get another just like this one. They stack exceptionally well. I am not really good with cutting foam, but it works.
