Like has been said before, each rifle is an individual and may have different requirements for accurate shooting. For some it makes no difference where the front rest is placed, but in general from reading about and owning several firearms with 2 piece stocks, some can be finicky at best in how and where they are supported. My .223 Ultra Varmint will shoot less than ½moa from a bipod, but when I put the .243 barrel on the same frame which has been factory fitted, it won't shoot from the same bipod worth a hoot, but shoots great from the hinge rest which the .223 barrel also does.
