I have a Savage Model 12 with a Varmint contour 6.5 Grendel barrel. I do alot of shooting and reloading for pistol and rifle calibers, but with this one rifle I find that 2-3 rounds out of 50 become FTF. The primers have firing pin dents in them but no bang. I had the trigger pull set at 2 1/2 # and then moved it to 3# and I still get the 1-2 FT. I was wondering if it is possible to change the weight of the bolt internal spring that the firing pin goes through. I can't find any information about the weight of the bolt firing pin spring pressures, so I am hoping someone can point me in the right direction. I have tried several primer mfgs. and have the same problems. Any ideas?
Thanks in advance for any help offered.
