Hi folks, I use Schmidt and bender pm2 on both my .308 and .243- I very rarely touch them once zeroed but noticed last time I changed to some home loads I had to change the zero on them.
So what has happened is that once happy with zero, I loosen off the grub screws and reset turret to zero to 0, but this then changes the zero. The only way round this I have found is to loosen the screws and pull the turret off and put on at 0.
Is this the norm, not double turrets standard ones. 3-12*50 mag!
