The good 209 conversion has excellent reviews. It will allow you to shoot Blackhorn209 powder and makes it far cleaner to shoot. The best thing about a 700ML is the TONS of aftermarket stuff. Basically anything that fits a Rem 700 centerfire fits a 700ML such as stocks, triggers and scope bases.

Google Arrow Head Sporting Goods LLC and talk to Luke. He will set you up with the 209 bolt nose kit and he offers installation. You need the "smoker" version if you want to stick with the factory barrel. If he does not have the smoker version in stock, he knows who does.

Reaching out to over 200 yards is much easier with a 45cal barrel upgrade. Then you can shoot either sabots or 45cal bullets without sabots. Does over 2300fps with a 275gr bullet sound good enough? Well that's just the beginning of what a sabotless 45cal can do.
