Re: How is a Rem 700 bolt handle attached...
One of the reasons how the load development you do is very important. If you find yourself having to use force to open the bolt, then you need to find a new load that doesnt infringe on the weapons operation. This is where the caution goes into the rounds you use. The right load will give the best accuracy, velocity and show no signs of pressure. Sounds blatantly obvious but I see lots of guys in the reloading section cramming as much powder into a cases, getting obvious pressure signs, and sticking with it. "The bolt sticks a little" to me is not acceptable for ammunition. Every time to have to "massage" the bolt open means you are putting unnecessay stress on parts not meant to take it.
Having a one piece bolt, tigging, tapped and screwed down may allow you to run a hotter round, but putting a little more effort into the load you use will save time and money on a new bolt and inventing a solution.
Someone said that if the USMC is running a factory bolt/handle then its good enough for them and I agree. If the Marines havent had problems with em breaking, which they are good at, then no one else should have as much issue. Not saying the factory doesnt put out a bad one now and then, or one happens to bust off during normal use. But like I said. Remington didnt build it to be beaten open due to hot bullets.
