Note the opening scene where the factory barrel was installed upside down with light grub screw torque... he couldn't budge the barrel. How much recoil energy is in a 22LR as compared to an adult male trying to wiggle the parts?
If we are discussing centerfire and larger chamberings, alot of this makes perfect sense... for a 22lr, my testing shows that an install that doesn't allow you to move the parts by hand is plenty good to extract what that barrel/ammo combo could do
Quality barrels, a suitable chamber, great match ammo, proper bedding... and today, a tuner, are the ingredients that seem to affect my results the most.
but... as always... YMMV
