While the Montana X-treme does keep the bore of the rifle in top condition, I personally think it is the design of the rifle and how they work that makes me able to shoot without swabbing the bore.

The White Rifle system is a high quality rifle and barrel. They are designed to shoot a slip fit conical. That means if the bore of the rifle is .504 then normally that bullet diameter is the same for best accuracy. I have actually shot over 20 shots without swabbing the rifle and while towards the end they start to load different, they do not load hard. You'd have to watch someone load a White with a slip fit conical. You seat the bullet with two fingers on the ramrod.

Actually my Ultra Mag shoots a .5045 best. The barrel bore measured .5045. The Bison has a different barrel maker and even though it is listed as .504 diameter it shoots a .503 or .5035 best. I shoot the No Excuses 460 grain out of it and they are .503.

Now Sabotloader got his hands on a Ultra Mag and discovered it is a fantastic sabot shooter. He has really pushed that limits of his White to do some amazing accuracy with sabots. I am not a sabot shooter in my White. I have other rifles for that.

Also cleanup was not that bad. Now granted with the open breech design and the fact I use a simple #11 cap for ignition, the breech of my rifle is FILTHY. That is OK with me. I know it is going to happen and I do not mind cleaning it. I have to put a bra on the scope. But other then that, the barrel itself cleans up really easy.

Also that Nikon Pro Staff.. while it is 2-7x32mm that has to be one of the best scopes for the money I have ever used. It is crystal clear, and tough. It has taken over 600 rounds now under its self, and never went out of line. And I take the scope off when I clean the rifle. I use Warne QR rings on the scope. It just makes cleaning the rifle that much easier.
