I ordered a 30-p1 a couple of weeks ago and it will be going on my r-700. It is a factory barreled action in an aics. It currently has a 26" .820 muzzle barrel and is shooting 3/8 moa with handloads. I have not had the barrel threaded yet, so I still have some options. I had one smith tell me that putting a 1 lb suppressor on the end of a 26" barrel will change the harmonics and I will lose accuracy. I have no problem cutting the barrel down to 20", but I don't really want to lose much velocity (and according to some, I may not). Question 1: What is your experience with longer barrels with a suppressor added? do they maintain accuracy? Question 2: How much velocity would I lose if I do cut to 20", thread, and recrown? I am currently running lapua brass, 43.5g varget, and 175smk's right at 2,600 fps.
