I'm looking at getting one of the Remmy 700 Tactical models and have a couple questions. I'm pretty set on the 20" Tactical model as I'm only planning on 300 yards max range and like way the gun handles. Remington has a fairly new offering of this rifle that uses 1:10 twist opposed to the 1:12 of the normal model. I'll be hand loading for it, so playing with bullet weights isn't a huge concern. Will I see a significant benefit with the faster twist with the short barrel? The main feature drawing me to the AAC model with the 1:10 twist is a factory threaded muzzle. I'd like to be able to use a muzzle brake on the rifle and if I ever move to a friendlier state, I could put a suppressor on it with ease. I can get both within a relatively similar price range. I'm hoping to get some opinions on both the barrel twists and the rifles from anyone who might own one. On a separate note, an older friend who did a good bit of high power rifle shooting really recommended using the Tubbs bore lapping system. It seams reasonably priced if it has any benefit at all.
