There is a mechanical reason for it. But if you don't see it happen with a fired case chambered then this particular behavior is not likely a problem.And I do believe that it is affecting accuracy. IMO, there's got to be a mechanical reason for it.
I have never heard that a scope could take a shot or two to "settle in".Your scope shouldn't be shifting. If its shifting under dry fire its definitely gonna shift with recoil when you do fire it.
Some scopes take 2 or 3 shots to "settle in" after adjusting.
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.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??
Can anyone help me out here? Getting used to the trigger on my gun. Its a Rem 700 thats been blueprinted, PTG bolt installed and lugs lapped, with a Proof steel barrel. Trigger Tech trigger set at 1# 3oz. Bolt bounces every time I dry fire it and scope POI shifts left 1/4" every time at 100 yds. Any ideas on what's the cause and how to eliminate this? Any help would be appreciated.
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
