I own a 07/15 longrifle 3 shot version of the French Berthier. This particular old rifle is not 'N' stamped on the barrel.
Something I've noticed about my Berthier is that the striker-spring is extremely heavy..The rifle requires some effort to open the bolt against the spring(cocks on opening)..and that it's virtually impossible to manually cock the striker.
I took the bolt apart...cleaned and inspected the internals...looked the mainspring over for originality..etc. Bolt works fine...feeds and fires fine. It has a original looking spring that's pretty powerful...all looks perfectly servicable and original.
Just how powerful should a Berthier mainspring be?
Is the spring so potent because of the capped primers some 8mm Lebel ammo is equipped with?
Thanx
