[QUOTE="thwatson2, post: 1989150, member: 56839"] Never talk anyone out of a build they want. That being said a 28 inch 308 isn’t comparable to a 20 inch 300wm. The longer length for magnums is for powder burn efficiency 308 is already extremely efficient so it doesn’t need tons of length to burn 42 grains of powder, but 72 grains needs more barrel length. if you want a 300wm in 20 inches go for it. You may find a dirty barrel and lower ballistics. Try to find the faster burning powders for a 300wm and you may get some better burn? As I love 300wm I’d take one in any length then work the powders to match the length [/QUOTE]
