[QUOTE="416Taylor, post: 1908110, member: 56474"] there are several mechanical reasons for bolt bounce. In no particular order they are: 1- firing spring (as previously mentioned) Several good options there. 2- most likely a bolt diameter issue. Keep in mind that when the bolt is placed in battery, there is upward spring pressure from the trigger sear. Any slop or tolerance is pushed up to the rear bridge of the action. upon firing the bolt is allowed to drop down causing the bolt handle to bounce. I generally see when there is several thousands or more of tolerance. i generally go for tight fitting bolts and I don’t see this issue. 3- as mentioned you could have a bolt timing issue. If the cocking piece is contacting the cocking ramp on its final journey forward it could cause the bolt to bounce. This is generally something that is way out of whack but can happen. I may have missed something but I believe there are the big ones. overall, you have a good shooting rifle so it may be a thing to live with?? [/QUOTE]
