Of course it was my opinion. But it's based on facts from my own experience with round recivers as well as those from other top ranked competitive shooters.
When folks started using Rem. 7XX actions for belted magnums in long range matches back in the middle of the last century and conventional epoxy bedding was first used, they held zeros for a hundred or two shots, then worked loose from barrel torque. Rebedding was the solution. I learned this with my first epoxy bedding job on a Rem. 700 action thinking it was the greatest thing for accuracy on earth. Then I learned that the reason Win. 70 actions were preferred for competition with cartridges .308 Win. and bigger shooting bullets weighing more than 160 grains.
The US military rifle teams also had the same problems with their 30 caliber magnums used in long range matches. Their attempt at fixing it was to make 2-inch long recoil lugs for their Remmy actions. That didn't work either. They finally put a flat bottom/side sleeve on them and that fixed the issue. No problems ever existed with their Win. 70 receivers.
Someone finally decided that what the benchresters did with 22 and 24 caliber rounds in Remmy actions sleeving them with flat bottom/side aluminum sleeves. Finally, accuracy with a round receiver would remain constant for the life of the barrel.
Of course, if folks cannot see their 1/4 MOA at 100 yard accuracy at worst lessen by 50% (goes to 3/8 MOA) or 600 yard accuracy go from 1/2 to 3/4 MOA, shooting their stuff for a couple hundered shots, then they won't notice the epoxy bedding has gone to pot. To them, the cause, effect and fix I mention is considered rediculous. I've been there, done that but learned from others and was able to tell the difference.
Action stiffness, as well as barrel stiffness, has never been critical for accuracy. As long as the barreled action behaves the same way for each shot, best accuracy is at hand. It's all about repeatability of movement of all the parts, not minimizing how much they move.
