what will the downfalls be with a muzzle heavy rifle for 600 yard shooting. Is it purely a bag riding issue? I am going to be doing a 6BRX on a new HaverKamp action with a 1.250 straight barrel. 27" long. stock will be a Mcmillan MBR. rifle will weight about 14.8 pounds without scope. I will add a little weight to the stock, but it will still be nose heavy, probably quite a bit. My main intent for this rifle is f-class/ prairie dogs but it would be nice to pull double duty on the bench. I have always like those big old barrels but i wonder if i should just send it back to Bruno and go with a HV instead. F-class allows 22 pounds and that will not be a problem, but 17 pounds may be! So is muzzle heavy rifle a bad thing? Thanks
