While having a larger more comfortable handle to operate the bolt with appeals to me, I wonder about the effects of that weight on the bolt.
First, the mass of the bolt is what controls the speed that it opens (And Closes) on firing.
Does the added weight make a noticeable difference? Is ejection changed? Does the slower closing bolt still feed ammo OK? Does it still work with 36 grain ammo?
Second, that bolt handle isn't really mounted to the bolt at all. It just sort of rides along in a slot.
The design basically beats it's self up in stock configuration by slamming into the sides of that slot every time the bolt opens or closes.
If you look at it, that bolt handle and the slot it rides in is where the worst wear in the gun occurs. It's visible the first time you shoot it and steadily gets looser with time. Fortunately, that looseness doesn't hurt anything, but it's there none the less.
Is adding extra weight out on the end of that bolt where it will have the most leverage and cause the largest increase in wear between the bolt and the lever a good idea?
Has anybody fired a million rounds with a heavy bolt handle? I'm curious to hear an extended use report on this.
