[QUOTE="MNbogboy, post: 1731511, member: 18849"] Sounds like you have probably covered these bases but here are things I would double check. Are FTF primers dented as normal? Is this accutrigger? ...no malfunction here like trigger rubbing sear? Recent rebarrel? Headspace may be good with gauges but have you matched your die bump settings to new chamber also? Also any recent brass change? Pockets uniformed to same depth? Primers seated to same depth (and/or crush)? Btw Savage pin setting .035-.055... I set mine. 040-.045 (lock tabs approx. .009) Then a few oddballs problems... 1. Bolt head retaining pin..cracked? 2. Bolt BAS screw loose? 3. Gum/rust/crud in bolt & go spring? 4. Sear pin walked out & out of place on one end? 5. Front action screw rubbing bolt head lug? Slight interference hard to feel but misaligns case, bolt head & fp....sharpie test finds this with case in chamber. 6. Never experienced a weak savage fp spring but certainly is possible. Has it or bolt been modified to relieve "lifting" force?.....if it has firing pin travel may have been reduced....the hard cups in your batch may have put reduced strike "over the edge". Hope you get it figured out, Randy [/QUOTE]
