I have read with bolt actions the best practice is to bed the receiver but allow the barrel to free float. With semi automatic piston rifles this is not possible because the barrel is connected to a gas tube which is connected to the receiver. Plus if it is a military rifle more often or not there is a bayonet lug and maybe a muzzle brake. To my understanding the concept of free floating a barrel doesn't work at all. I have a semi auto, FN49, which is proven capable of sub MOA accuracy but I have read reports (complaints) of shot stringing. Wouldn't accuracy in a design that already constrains free floating barrels benefit from the opposite, bedding as much of the barrel as possible? I guess trying to get the effect of a thicker bull barrel.
Remember I am asking for illumination senseis. Along the same line is harmonics. This is part of a conversation I was having with someone about muzzle brakes.
---------
Reloading will require a different load due to changed harmonics. If the muzzle brake is tightened too much it will cause some torque to the bore and will diminish the rifle's accuracy. It does not take a lot of torque to cause problems. The answer is to only snug the brake gently, yet firmly to the threads, not going over 15 - 20 lbs of torque.
-----------------
I can't really see if you over tighten something threaded a bit everything is going to go to hell in a hand basket. I mean the barrel is thick and whatever torqued force would be on the outside just at the thread line.
I can see how adding some weight to the end of the barrel can change dynamics.
If I could get rid of the bayonet lug would it have a positive effect on accuracy?
Bottom line with a barrel with a piston attached would it be a good idea to have as little stuff hanging on it as possible and to bed more of the barrel?
