[QUOTE="Blackhawk, post: 1998382, member: 105459"] [B]As stated your primer pockets are clean, and you still encounter misfires. Here are my thoughts.[/B][I] ( I use CCI #250 primers in my 300,& 338 Win Mags and never had a problem ) In order by process of elimination, you must consider the following but personally, I think that it is your primers that are the problem. Are they from the same batch and lot? If so consider trying a different lot number. (if you can find em) and please follow along. If possible clean and deburr the flash hole from inside the case .this is especially so on virgin brass hulls. Even though I tumble my brass in pin media, I still remove the residuals that are left in the primer pocket by using a Lyman Case Prep Express cleaning tool. I do not believe that your brand of brass is not an issue however your primer pockets may be. In that light just eliminate that problem and just clean your primer pockets. (You would be surprised as to what is left in the primer pocket even on virgin brass) [B][COLOR=rgb(97, 189, 109)]I know that this may seem like a lot of extra work but it is one way of eliminating either the primer or the firing pin as the culprit of your problem so please read on! [/COLOR][/B] [COLOR=rgb(0, 0, 0)]Now after all the preliminary case adjustments[/COLOR][B][COLOR=rgb(97, 189, 109)] [/COLOR][/B][COLOR=rgb(0, 0, 0)]are m[/COLOR]ade you can seat your primers. I use a hand seating tool from Frankford Arsenal just for this purpose. It is one of the few priming tools that allows for perfect seating of any primer because it has an adjustment for an exact seating depth of your primer simply by turning a wheel. Now that your primer is seated correctly -.003" below flush you are ready. 1) Prime five rounds without powder or bullet and [COLOR=rgb(97, 189, 109)]because CCI #250 primers are on the hard side[/COLOR] prime only and set aside. 2) Using several brands of Magnum primers (if you can find them ) repeat the process and prime only more bass hulls. 3) Mark each of the cases with a Sharpie identifying the primers that you loaded. 4) In a safe location load a case( primer only without either powder or bullet) and pull the trigger. 5) Repeat until you have shot off all your cases. Did any fail to fire? If so which brand., or did you experience a failure to fire with several brands of primers?[/I] [B]If you have gone this far and experienced a failure to fire on all three rifles using different primers well you have either eliminated your primers by finding the problem primer brand or must look at the firing pin and spring assemblies.[/B] [I]Take apart your bolts and remove the firing pin and spring assembly. After you examine both, clean your spring and firing pin thoroughly then lightly oil and I mean lightly with say Rem Oil and set aside. ( perform this on all three of your rifles) Now attack the bolt faces If needed remove the extractor then proceed to give the bolt face a thorough cleaning. After wiping down your bolt and firing pin assembly replace the extractor and reassemble your bolt. If all looks good I would again make up several primed only cases and repeat the test outlined above. If you still experience either a light primer strike or a failure to fire well then I believe that either a new firing pin and spring combination will solve your problems. I would consider replacing your firing pin spring first as a week sping will cause plenty of headaches until it is replaced. [B]But honestly, I believe that the problem stems from your brand of primer, primer seating depth, primer pockets, and or the flash holes themselves as this is happening not just with one, but all three rifles. In that light, I tend to think that your bolt assemblies and firing pins on all three rifles are OK and not your culprits. Sincerely hope that this longwinded dissertation will give you some food for thought![/B][/I] [/QUOTE]
