A guess,
weather has changed a bit this year. Sometimes the wood in the stock will expand/contract so as to rub the parts.
Are you skilled enough to remove the stock and evaluate it for rub marks? Also, while the stock is off, check for proper lubrication and clean the sear areas.

p.s. and Yes the reloads could induce some issues, try the gun with some light factory ammo and see if the problems still happen.
p.s.s. also really clean the chambers and forcing cones.
