Ilion accidentally sold me a 24" bull (varmint) barrel several years ago when I had ordered a std contour. I just kept it and never complained, but now wish I had sent it back. I find its too heavy to carry comfortably all day (as compared to my 44mag barrel). And oddly, that extra 2" on the barrel always seems to be catching on something. Finally, it doesn't balance well (on my plastic-stocked gun). Balance point is well forward of the hinge pin, and I have to set the forend on the bag. With handi's, I prefer to put the bag under the hinge-pin. I've considered adding weight to the butt stock, but that would make it even heavier to carry. 22" bull may not have those issues, I've never tried one. My other barrels are all 22" pistol calibers.
