Just wondering if any of you have ever installed one of these before. This will be going on a Remington 700 300 RUM tomorrow. The instructions say 65 lbs. on each screw. I have read elsewhere that you need 45-50 lbs. I am the type of guy that will put the screws in and say good enough. Will my way work or do I need to get this exactly perfect! Also, if you have experience with this stock, will the barrel be free floated or will I have to tackle that later? Thanks in advance!
