  1. Does the whole bolt move foward or just the firing pin? I've not noticed this but it might not be a problem.
  
  2. The gun might just be stiff from lack of use... or it could be a sign of a couple of things, including insufficient/too much headspace, too hot a load (though with a 98 action it is hard to fathom that it could be dangerous) or cracked case neck.
  
  3. Gunpartscorp has the blueprints available for many guns though I don't know about this one, for a minor fee though they aren't too detailed. It is also in their catalog, though basically the diagram is the same for any 98 action.

  johnb--the problem with the gun being hard to open after firing may be due to impressed locking lug seats, which would translate to too much headspace when the bolt is in the locked position. If the bolt closes OK on a new commercial cartridge and then can be re-opened with normal effort (not fired) you need to have a gunsmith check it out for you. If the gun opens after firing with undue effort, it's because the case stretches enough when it's fired to cause a mechanical lock, and then when you go to open the action you're compressing the case as the lugs rotate out of the impressions.

  sorry for lack of info, it is firing pin that is moving slightly,once bolt is cocked extraction of fired case is normal,cases show no signs of stress, John

  Since the Mauser action "cocks on open", is the area of the reciever that the bolt handle povits aginst smooth? If its not smooth or appears rough or choppy this could also make it hard to open and you may have a reciever that isn't properly heat treated ... the problem could also be in the bolt handle if its rough where it works aginst the reciever ... to check, see if the action is hard to open when you release the firing pin on a empty chamber (or use a snap-cap or fired case); If it's still hard to open, you have a camming problem ... I ren into this problem when refitting a bent bolt to a Turk Mauser so I could scope it ...

  johnb,You could try polishing the cocking ramps on the cocking peice and bolt.I use a cratex wheel in my dremmel.Don't work it so hard as to remove noticable metal,just enough to make it mirror bright.Then a little grease on those surfaces should help some.It also will help(your trigger) to do the same on the sear and the cocking peice surface.Good Luck,Roger(heckmanj@ptsi.net)

  The striker(firing pin) is supposed to move forward slightly when the safety is released. The safety pulls the striker to the rear when engaged out of contact with the sear. The previous line about impressed bolt lug seats is probably correct. Have you disassembled the bolt and cleaned it inside and out? I have one here right now that had so much grease inside the bolt that it would barely come apart. Does it only "cock" hard after actually firing a round or any time you open the bolt from the uncocked position? There can be burrs or galled places inside the cocking piece that can cause problems. Good luck. If the lug seats are set back you'ld be better off hanging it up and starting over. The primary reason for this is the bolt is harder than the action and heavy use and/or high pressure can hammer the seats until they are worn back past specs.

  1.bolt (firing pin) moves slightly forward when safety released,,is this common??
  This is perfectly normal, because the safety cams the firing pin back away from the sear and locks it in this position. when you release the safety the firing pin returned to it's sear contact position.
  
  It also sounds like you may have some crud or galling on the cocking cam surfaces. It only takes a minute to completly strip a Mauser bolt down. 1-Unload the weapon 2-with the striker cocked, apply the safety to it's center position (streight up) 3-remove the bolt from the rifle 4-unscrew the bolt shroud from the bolt body (their may be a visable detent that needs to be depressed) 5-holding the bolt shroud, press the tip of the firing pin into a flat surface firmly, until the sear piece can be rotated 90deg and lifted off (if there is a washer looking metal piece (with a small hole in it) on the buttstock, you can place the tip of the firing pin in the hole (thats what it's there for) 6- release the pressure on the bolt shroud 7-assemble in reverse order

  I think the answer lies in the cocking mechanism,yes I have disassembled bolt and cleaned.will do so again checking closely the cam surface.. could this have a stronger pin spring than needed???? thanks again John
